+Thank you for opening an issue on an Adafruit Arduino library repository.  To
+improve the speed of resolution please review the following guidelines and
+common troubleshooting steps below before creating the issue:
+
+- **Do not use GitHub issues for troubleshooting projects and issues.**  Instead use
+  the forums at http://forums.adafruit.com to ask questions and troubleshoot why
+  something isn't working as expected.  In many cases the problem is a common issue
+  that you will more quickly receive help from the forum community.  GitHub issues
+  are meant for known defects in the code.  If you don't know if there is a defect
+  in the code then start with troubleshooting on the forum first.
+
+- **If following a tutorial or guide be sure you didn't miss a step.** Carefully
+  check all of the steps and commands to run have been followed.  Consult the
+  forum if you're unsure or have questions about steps in a guide/tutorial.
+
+- **For Arduino projects check these very common issues to ensure they don't apply**:
+
+  - For uploading sketches or communicating with the board make sure you're using
+    a **USB data cable** and **not** a **USB charge-only cable**.  It is sometimes
+    very hard to tell the difference between a data and charge cable!  Try using the
+    cable with other devices or swapping to another cable to confirm it is not
+    the problem.
+
+  - **Be sure you are supplying adequate power to the board.**  Check the specs of
+    your board and plug in an external power supply.  In many cases just
+    plugging a board into your computer is not enough to power it and other
+    peripherals.
+
+  - **Double check all soldering joints and connections.**  Flakey connections
+    cause many mysterious problems.  See the [guide to excellent soldering](https://learn.adafruit.com/adafruit-guide-excellent-soldering/tools) for examples of good solder joints.
+
+  - **Ensure you are using an official Arduino or Adafruit board.** We can't
+    guarantee a clone board will have the same functionality and work as expected
+    with this code and don't support them.
+
+If you're sure this issue is a defect in the code and checked the steps above
+please fill in the following fields to provide enough troubleshooting information.
+You may delete the guideline and text above to just leave the following details:
+
+- Arduino board:  **INSERT ARDUINO BOARD NAME/TYPE HERE**
+
+- Arduino IDE version (found in Arduino -> About Arduino menu):  **INSERT ARDUINO
+  VERSION HERE**
+
+- List the steps to reproduce the problem below (if possible attach a sketch or
+  copy the sketch code in too): **LIST REPRO STEPS BELOW**

+Thank you for creating a pull request to contribute to Adafruit's GitHub code!
+Before you open the request please review the following guidelines and tips to
+help it be more easily integrated:
+
+- **Describe the scope of your change--i.e. what the change does and what parts
+  of the code were modified.**  This will help us understand any risks of integrating
+  the code.
+
+- **Describe any known limitations with your change.**  For example if the change
+  doesn't apply to a supported platform of the library please mention it.
+
+- **Please run any tests or examples that can exercise your modified code.**  We
+  strive to not break users of the code and running tests/examples helps with this
+  process.
+
+Thank you again for contributing!  We will try to test and integrate the change
+as soon as we can, but be aware we have many GitHub repositories to manage and
+can't immediately respond to every request.  There is no need to bump or check in
+on a pull request (it will clutter the discussion of the request).
+
+Also don't be worried if the request is closed or not integrated--sometimes the
+priorities of Adafruit's GitHub code (education, ease of use) might not match the
+priorities of the pull request.  Don't fret, the open source community thrives on
+forks and GitHub makes it easy to keep your changes in a forked repo.
+
+After reviewing the guidelines above you can delete this text from the pull request.

+Thank you for opening an issue on an Adafruit Arduino library repository.  To
+improve the speed of resolution please review the following guidelines and
+common troubleshooting steps below before creating the issue:
+
+- **Do not use GitHub issues for troubleshooting projects and issues.**  Instead use
+  the forums at http://forums.adafruit.com to ask questions and troubleshoot why
+  something isn't working as expected.  In many cases the problem is a common issue
+  that you will more quickly receive help from the forum community.  GitHub issues
+  are meant for known defects in the code.  If you don't know if there is a defect
+  in the code then start with troubleshooting on the forum first.
+
+- **If following a tutorial or guide be sure you didn't miss a step.** Carefully
+  check all of the steps and commands to run have been followed.  Consult the
+  forum if you're unsure or have questions about steps in a guide/tutorial.
+
+- **For Arduino projects check these very common issues to ensure they don't apply**:
+
+  - For uploading sketches or communicating with the board make sure you're using
+    a **USB data cable** and **not** a **USB charge-only cable**.  It is sometimes
+    very hard to tell the difference between a data and charge cable!  Try using the
+    cable with other devices or swapping to another cable to confirm it is not
+    the problem.
+
+  - **Be sure you are supplying adequate power to the board.**  Check the specs of
+    your board and plug in an external power supply.  In many cases just
+    plugging a board into your computer is not enough to power it and other
+    peripherals.
+
+  - **Double check all soldering joints and connections.**  Flakey connections
+    cause many mysterious problems.  See the [guide to excellent soldering](https://learn.adafruit.com/adafruit-guide-excellent-soldering/tools) for examples of good solder joints.
+
+  - **Ensure you are using an official Arduino or Adafruit board.** We can't
+    guarantee a clone board will have the same functionality and work as expected
+    with this code and don't support them.
+
+If you're sure this issue is a defect in the code and checked the steps above
+please fill in the following fields to provide enough troubleshooting information.
+You may delete the guideline and text above to just leave the following details:

+Thank you for creating a pull request to contribute to Adafruit's GitHub code!
+Before you open the request please review the following guidelines and tips to
+help it be more easily integrated:
+
+- **Describe the scope of your change--i.e. what the change does and what parts
+  of the code were modified.**  This will help us understand any risks of integrating
+  the code.
+
+- **Describe any known limitations with your change.**  For example if the change
+  doesn't apply to a supported platform of the library please mention it.
+
+- **Please run any tests or examples that can exercise your modified code.**  We
+  strive to not break users of the code and running tests/examples helps with this
+  process.
+
+Thank you again for contributing!  We will try to test and integrate the change
+as soon as we can, but be aware we have many GitHub repositories to manage and
+can't immediately respond to every request.  There is no need to bump or check in
+on a pull request (it will clutter the discussion of the request).
+
+Also don't be worried if the request is closed or not integrated--sometimes the
+priorities of Adafruit's GitHub code (education, ease of use) might not match the
+priorities of the pull request.  Don't fret, the open source community thrives on
+forks and GitHub makes it easy to keep your changes in a forked repo.
+
+After reviewing the guidelines above you can delete this text from the pull request.

+# Adafruit Unified Sensor Driver #
+
+Many small embedded systems exist to collect data from sensors, analyse the data, and either take an appropriate action or send that sensor data to another system for processing.
+
+One of the many challenges of embedded systems design is the fact that parts you used today may be out of production tomorrow, or system requirements may change and you may need to choose a different sensor down the road.
+
+Creating new drivers is a relatively easy task, but integrating them into existing systems is both error prone and time consuming since sensors rarely use the exact same units of measurement.
+
+By reducing all data to a single **sensors\_event\_t** 'type' and settling on specific, **standardised SI units** for each sensor family the same sensor types return values that are comparable with any other similar sensor.  This enables you to switch sensor models with very little impact on the rest of the system, which can help mitigate some of the risks and problems of sensor availability and code reuse.
+
+The unified sensor abstraction layer is also useful for data-logging and data-transmission since you only have one well-known type to log or transmit over the air or wire.
+

+
+## How Does it Work? ##
+
+Any driver that supports the Adafruit unified sensor abstraction layer will implement the Adafruit\_Sensor base class.  There are two main typedefs and one enum defined in Adafruit_Sensor.h that are used to 'abstract' away the sensor details and values:
+
+## Sensor Types (`sensors_type_t`)
+
+These pre-defined sensor types are used to properly handle the two related typedefs below, and allows us determine what types of units the sensor uses, etc.
+
+```c++
+/** Sensor types */
+typedef enum
+{
+  SENSOR_TYPE_ACCELEROMETER         = (1),
+  SENSOR_TYPE_MAGNETIC_FIELD        = (2),
+  SENSOR_TYPE_ORIENTATION           = (3),
+  SENSOR_TYPE_GYROSCOPE             = (4),
+  SENSOR_TYPE_LIGHT                 = (5),
+  SENSOR_TYPE_PRESSURE              = (6),
+  SENSOR_TYPE_PROXIMITY             = (8),
+  SENSOR_TYPE_GRAVITY               = (9),
+  SENSOR_TYPE_LINEAR_ACCELERATION   = (10),
+  SENSOR_TYPE_ROTATION_VECTOR       = (11),
+  SENSOR_TYPE_RELATIVE_HUMIDITY     = (12),
+  SENSOR_TYPE_AMBIENT_TEMPERATURE   = (13),
+  SENSOR_TYPE_VOLTAGE               = (15),
+  SENSOR_TYPE_CURRENT               = (16),
+  SENSOR_TYPE_COLOR                 = (17),
+  SENSOR_TYPE_TVOC                  = (18),
+  SENSOR_TYPE_VOC_INDEX             = (19),
+  SENSOR_TYPE_NOX_INDEX             = (20),
+  SENSOR_TYPE_CO2                   = (21),
+  SENSOR_TYPE_ECO2                  = (22),
+  SENSOR_TYPE_PM10_STD              = (23),
+  SENSOR_TYPE_PM25_STD              = (24),
+  SENSOR_TYPE_PM100_STD             = (25),
+  SENSOR_TYPE_PM10_ENV              = (26),
+  SENSOR_TYPE_PM25_ENV              = (27),
+  SENSOR_TYPE_PM100_ENV             = (28),
+  SENSOR_TYPE_GAS_RESISTANCE        = (29),
+  SENSOR_TYPE_UNITLESS_PERCENT      = (30),
+  SENSOR_TYPE_ALTITUDE              = (31),
+} sensors_type_t;
+```
+
+## Sensor Details (`sensor_t`)
+
+This typedef describes the specific capabilities of this sensor, and allows us to know what sensor we are using beneath the abstraction layer.
+
+```c++
+/* Sensor details (40 bytes) */
+/** struct sensor_s is used to describe basic information about a specific sensor. */
+typedef struct
+{
+    char     name[12];
+    int32_t  version;
+    int32_t  sensor_id;
+    int32_t  type;
+    float    max_value;
+    float    min_value;
+    float    resolution;
+    int32_t  min_delay;
+} sensor_t;
+```
+
+The individual fields are intended to be used as follows:
+
+- **name**: The sensor name or ID, up to a maximum of twelve characters (ex. "MPL115A2")
+- **version**: The version of the sensor HW and the driver to allow us to differentiate versions of the board or driver
+- **sensor\_id**: A unique sensor identifier that is used to differentiate this specific sensor instance from any others that are present on the system or in the sensor network
+- **type**: The sensor type, based on **sensors\_type\_t** in sensors.h
+- **max\_value**: The maximum value that this sensor can return (in the appropriate SI unit)
+- **min\_value**: The minimum value that this sensor can return (in the appropriate SI unit)
+- **resolution**: The smallest difference between two values that this sensor can report (in the appropriate SI unit)
+- **min\_delay**: The minimum delay in microseconds between two sensor events, or '0' if there is no constant sensor rate
+
+## Sensor Data/Events (`sensors_event_t`)
+
+This typedef is used to return sensor data from any sensor supported by the abstraction layer, using standard SI units and scales.
+
+```c++
+/* Sensor event (36 bytes) */
+/** struct sensor_event_s is used to provide a single sensor event in a common format. */
+typedef struct
+{
+    int32_t version;
+    int32_t sensor_id;
+    int32_t type;
+    int32_t reserved0;
+    int32_t timestamp;
+    union
+    {
+        float           data[4];
+        sensors_vec_t   acceleration;
+        sensors_vec_t   magnetic;
+        sensors_vec_t   orientation;
+        sensors_vec_t   gyro;
+        float           temperature;
+        float           distance;
+        float           light;
+        float           pressure;
+        float           relative_humidity;
+        float           current;
+        float           voltage;
+        float           tvoc;
+        float           voc_index;
+        float           nox_index;
+        float           CO2,
+        float           eCO2,
+        float           pm10_std,
+        float           pm25_std,
+        float           pm100_std,
+        float           pm10_env,
+        float           pm25_env,
+        float           pm100_env,
+        float           gas_resistance,
+        float           unitless_percent,
+        float           altitude,
+        sensors_color_t color;
+    };
+} sensors_event_t;
+```
+It includes the following fields:
+
+- **version**: Contain 'sizeof(sensors\_event\_t)' to identify which version of the API we're using in case this changes in the future
+- **sensor\_id**: A unique sensor identifier that is used to differentiate this specific sensor instance from any others that are present on the system or in the sensor network (must match the sensor\_id value in the corresponding sensor\_t enum above!)
+- **type**: the sensor type, based on **sensors\_type\_t** in sensors.h
+- **timestamp**: time in milliseconds when the sensor value was read
+- **data[4]**: An array of four 32-bit values that allows us to encapsulate any type of sensor data via a simple union (further described below)
+
+## Required Functions
+
+In addition to the two standard types and the sensor type enum, all drivers based on Adafruit_Sensor must also implement the following two functions:
+
+```c++
+bool getEvent(sensors_event_t*);
+```
+Calling this function will populate the supplied sensors\_event\_t reference with the latest available sensor data.  You should call this function as often as you want to update your data.
+
+```c++
+void getSensor(sensor_t*);
+```
+Calling this function will provide some basic information about the sensor (the sensor name, driver version, min and max values, etc.
+
+## Standardised SI values for `sensors_event_t`
+
+A key part of the abstraction layer is the standardization of values on SI units of a particular scale, which is accomplished via the data[4] union in sensors\_event\_t above.  This 16 byte union includes fields for each main sensor type, and uses the following SI units and scales:
+
+- **acceleration**: values are in **meter per second per second** (m/s^2)
+- **magnetic**: values are in **micro-Tesla** (uT)
+- **orientation**: values are in **degrees**
+- **gyro**: values are in **rad/s**
+- **temperature**: values in **degrees centigrade** (Celsius) 
+- **distance**: values are in **centimeters**
+- **light**: values are in **SI lux** units
+- **pressure**: values are in **hectopascal** (hPa)
+- **relative\_humidity**: values are in **percent**
+- **current**: values are in **milliamps** (mA)
+- **voltage**: values are in **volts** (V)
+- **color**: values are in 0..1.0 RGB channel luminosity and 32-bit RGBA format
+- **tvoc**: values are in **parts per billion** (ppb)
+- **voc_index**: values are an **index** from 1-500 with 100 being normal
+- **nox_index**: values are an **index** from 1-500 with 100 being normal
+- **CO2**: values are in **parts per million** (ppm)
+- **eCO2**: values are in **parts per million** (ppm)
+- **pm10_std**: values are in **parts per million** (ppm)
+- **pm25_std**: values are in **parts per million** (ppm)
+- **pm100_std**: values are in **parts per million** (ppm)
+- **pm10_env**: values are in **parts per million** (ppm)
+- **pm25_env**: values are in **parts per million** (ppm)
+- **pm100_env**: values are in **parts per million** (ppm)
+- **gas_resistance**: values are in **ohms**
+- **unitless_percent**: values are in **%**
+- **altitude**: values are in **meters** (m)
+
+## The Unified Driver Abstraction Layer in Practice ##
+
+Using the unified sensor abstraction layer is relatively easy once a compliant driver has been created.
+
+Every compliant sensor can now be read using a single, well-known 'type' (sensors\_event\_t), and there is a standardized way of interrogating a sensor about its specific capabilities (via sensor\_t).
+
+An example of reading the [TSL2561](https://github.com/adafruit/Adafruit_TSL2561) light sensor can be seen below:
+
+```c++
+ Adafruit_TSL2561 tsl = Adafruit_TSL2561(TSL2561_ADDR_FLOAT, 12345);
+ ...
+ /* Get a new sensor event */ 
+ sensors_event_t event;
+ tsl.getEvent(&event);
+ 
+ /* Display the results (light is measured in lux) */
+ if (event.light)
+ {
+   Serial.print(event.light); Serial.println(" lux");
+ }
+ else
+ {
+   /* If event.light = 0 lux the sensor is probably saturated
+      and no reliable data could be generated! */
+   Serial.println("Sensor overload");
+ }
+```
+
+Similarly, we can get the basic technical capabilities of this sensor with the following code:
+
+```c++
+ sensor_t sensor;
+ 
+ sensor_t sensor;
+ tsl.getSensor(&sensor);
+
+ /* Display the sensor details */
+ Serial.println("------------------------------------");
+ Serial.print  ("Sensor:       "); Serial.println(sensor.name);
+ Serial.print  ("Driver Ver:   "); Serial.println(sensor.version);
+ Serial.print  ("Unique ID:    "); Serial.println(sensor.sensor_id);
+ Serial.print  ("Max Value:    "); Serial.print(sensor.max_value); Serial.println(" lux");
+ Serial.print  ("Min Value:    "); Serial.print(sensor.min_value); Serial.println(" lux");
+ Serial.print  ("Resolution:   "); Serial.print(sensor.resolution); Serial.println(" lux");  
+ Serial.println("------------------------------------");
+ Serial.println("");
+```

+  something isn't working as expected.  In many cases the problem is a common issue
+  that you will more quickly receive help from the forum community.  GitHub issues
+  are meant for known defects in the code.  If you don't know if there is a defect
+  in the code then start with troubleshooting on the forum first.
+
+- **If following a tutorial or guide be sure you didn't miss a step.** Carefully
+  check all of the steps and commands to run have been followed.  Consult the
+  forum if you're unsure or have questions about steps in a guide/tutorial.
+
+- **For Arduino projects check these very common issues to ensure they don't apply**:
+
+  - For uploading sketches or communicating with the board make sure you're using
+    a **USB data cable** and **not** a **USB charge-only cable**.  It is sometimes
+    very hard to tell the difference between a data and charge cable!  Try using the
+    cable with other devices or swapping to another cable to confirm it is not
+    the problem.
+
+  - **Be sure you are supplying adequate power to the board.**  Check the specs of
+    your board and plug in an external power supply.  In many cases just
+    plugging a board into your computer is not enough to power it and other
+    peripherals.
+
+  - **Double check all soldering joints and connections.**  Flakey connections
+    cause many mysterious problems.  See the [guide to excellent soldering](https://learn.adafruit.com/adafruit-guide-excellent-soldering/tools) for examples of good solder joints.
+
+  - **Ensure you are using an official Arduino or Adafruit board.** We can't
+    guarantee a clone board will have the same functionality and work as expected
+    with this code and don't support them.
+
+If you're sure this issue is a defect in the code and checked the steps above
+please fill in the following fields to provide enough troubleshooting information.

+Thank you for creating a pull request to contribute to Adafruit's GitHub code!
+Before you open the request please review the following guidelines and tips to
+help it be more easily integrated:
+
+- **Describe the scope of your change--i.e. what the change does and what parts
+  of the code were modified.**  This will help us understand any risks of integrating
+  the code.
+
+- **Describe any known limitations with your change.**  For example if the change
+  doesn't apply to a supported platform of the library please mention it.
+
+- **Please run any tests or examples that can exercise your modified code.**  We
+  strive to not break users of the code and running tests/examples helps with this
+  process.
+
+Thank you again for contributing!  We will try to test and integrate the change
+as soon as we can, but be aware we have many GitHub repositories to manage and
+can't immediately respond to every request.  There is no need to bump or check in
+on a pull request (it will clutter the discussion of the request).
+
+Also don't be worried if the request is closed or not integrated--sometimes the
+priorities of Adafruit's GitHub code (education, ease of use) might not match the
+priorities of the pull request.  Don't fret, the open source community thrives on
+forks and GitHub makes it easy to keep your changes in a forked repo.
+
+After reviewing the guidelines above you can delete this text from the pull request.

+# Contribution Guidlines
+
+This library is the culmination of the expertise of many members of the open source community who have dedicated their time and hard work. The best way to ask for help or propose a new idea is to [create a new issue](https://github.com/adafruit/DHT-sensor-library/issues/new) while creating a Pull Request with your code changes allows you to share your own innovations with the rest of the community.
+
+The following are some guidelines to observe when creating issues or PRs:
+
+- Be friendly; it is important that we can all enjoy a safe space as we are all working on the same project and it is okay for people to have different ideas
+
+- [Use code blocks](https://github.com/adam-p/markdown-here/wiki/Markdown-Cheatsheet#code); it helps us help you when we can read your code! On that note also refrain from pasting more than 30 lines of code in a post, instead [create a gist](https://gist.github.com/) if you need to share large snippets
+
+- Use reasonable titles; refrain from using overly long or capitalized titles as they are usually annoying and do little to encourage others to help :smile:
+
+- Be detailed; refrain from mentioning code problems without sharing your source code and always give information regarding your board and version of the library

+# Adafruit Community Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and leaders pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level or type of
+experience, education, socio-economic status, nationality, personal appearance,
+race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+We are committed to providing a friendly, safe and welcoming environment for
+all.
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Be kind and courteous to others
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Collaborating with other community members
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and sexual attention or advances
+* The use of inappropriate images, including in a community member's avatar
+* The use of inappropriate language, including in a community member's nickname
+* Any spamming, flaming, baiting or other attention-stealing behavior
+* Excessive or unwelcome helping; answering outside the scope of the question
+  asked
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate
+
+The goal of the standards and moderation guidelines outlined here is to build
+and maintain a respectful community. We ask that you don’t just aim to be
+"technically unimpeachable", but rather try to be your best self. 
+
+We value many things beyond technical expertise, including collaboration and
+supporting others within our community. Providing a positive experience for
+other community members can have a much more significant impact than simply
+providing the correct answer.
+
+## Our Responsibilities
+
+Project leaders are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project leaders have the right and responsibility to remove, edit, or
+reject messages, comments, commits, code, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any community member for other behaviors that they deem
+inappropriate, threatening, offensive, or harmful.
+
+## Moderation
+
+Instances of behaviors that violate the Adafruit Community Code of Conduct
+may be reported by any member of the community. Community members are
+encouraged to report these situations, including situations they witness
+involving other community members.
+
+You may report in the following ways:
+
+In any situation, you may send an email to <support@adafruit.com>.
+
+On the Adafruit Discord, you may send an open message from any channel
+to all Community Helpers by tagging @community helpers. You may also send an
+open message from any channel, or a direct message to @kattni#1507,
+@tannewt#4653, @Dan Halbert#1614, @cater#2442, @sommersoft#0222, or
+@Andon#8175.
+
+Email and direct message reports will be kept confidential.
+
+In situations on Discord where the issue is particularly egregious, possibly
+illegal, requires immediate action, or violates the Discord terms of service,
+you should also report the message directly to Discord.
+
+These are the steps for upholding our community’s standards of conduct.
+
+1. Any member of the community may report any situation that violates the
+Adafruit Community Code of Conduct. All reports will be reviewed and
+investigated.
+2. If the behavior is an egregious violation, the community member who
+committed the violation may be banned immediately, without warning.
+3. Otherwise, moderators will first respond to such behavior with a warning.
+4. Moderators follow a soft "three strikes" policy - the community member may
+be given another chance, if they are receptive to the warning and change their
+behavior.
+5. If the community member is unreceptive or unreasonable when warned by a
+moderator, or the warning goes unheeded, they may be banned for a first or
+second offense. Repeated offenses will result in the community member being
+banned.
+
+## Scope
+
+This Code of Conduct and the enforcement policies listed above apply to all
+Adafruit Community venues. This includes but is not limited to any community
+spaces (both public and private), the entire Adafruit Discord server, and
+Adafruit GitHub repositories. Examples of Adafruit Community spaces include
+but are not limited to meet-ups, audio chats on the Adafruit Discord, or
+interaction at a conference.
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. As a community
+member, you are representing our community, and are expected to behave
+accordingly.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage],
+version 1.4, available at
+<https://www.contributor-covenant.org/version/1/4/code-of-conduct.html>,
+and the [Rust Code of Conduct](https://www.rust-lang.org/en-US/conduct.html).
+
+For other projects adopting the Adafruit Community Code of
+Conduct, please contact the maintainers of those projects for enforcement.
+If you wish to use this code of conduct for your own project, consider
+explicitly mentioning your moderation policy or making a copy with your
+own moderation policy so as to avoid confusion.

+# Arduino Client for MQTT
+
+This library provides a client for doing simple publish/subscribe messaging with
+a server that supports MQTT.
+
+## Examples
+
+The library comes with a number of example sketches. See File > Examples > PubSubClient
+within the Arduino application.
+
+Full API documentation is available here: https://pubsubclient.knolleary.net
+
+## Limitations
+
+ - It can only publish QoS 0 messages. It can subscribe at QoS 0 or QoS 1.
+ - The maximum message size, including header, is **256 bytes** by default. This
+   is configurable via `MQTT_MAX_PACKET_SIZE` in `PubSubClient.h` or can be changed
+   by calling `PubSubClient::setBufferSize(size)`.
+ - The keepalive interval is set to 15 seconds by default. This is configurable
+   via `MQTT_KEEPALIVE` in `PubSubClient.h` or can be changed by calling
+   `PubSubClient::setKeepAlive(keepAlive)`.
+ - The client uses MQTT 3.1.1 by default. It can be changed to use MQTT 3.1 by
+   changing value of `MQTT_VERSION` in `PubSubClient.h`.
+
+
+## Compatible Hardware
+
+The library uses the Arduino Ethernet Client api for interacting with the
+underlying network hardware. This means it Just Works with a growing number of
+boards and shields, including:
+
+ - Arduino Ethernet
+ - Arduino Ethernet Shield
+ - Arduino YUN – use the included `YunClient` in place of `EthernetClient`, and
+   be sure to do a `Bridge.begin()` first
+ - Arduino WiFi Shield - if you want to send packets > 90 bytes with this shield,
+   enable the `MQTT_MAX_TRANSFER_SIZE` define in `PubSubClient.h`.
+ - Sparkfun WiFly Shield – [library](https://github.com/dpslwk/WiFly)
+ - TI CC3000 WiFi - [library](https://github.com/sparkfun/SFE_CC3000_Library)
+ - Intel Galileo/Edison
+ - ESP8266
+ - ESP32
+
+The library cannot currently be used with hardware based on the ENC28J60 chip –
+such as the Nanode or the Nuelectronics Ethernet Shield. For those, there is an
+[alternative library](https://github.com/njh/NanodeMQTT) available.
