-# Adafruit Community Code of Conduct
+# Contributor Covenant 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
+contributors and maintainers 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.
+size, disability, ethnicity, gender identity and expression, level of experience,
+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
+* The use of sexualized language or imagery and unwelcome sexual attention or
+advances
 * Trolling, insulting/derogatory comments, and personal or political attacks
-* Promoting or spreading disinformation, lies, or conspiracy theories against
-  a person, group, organisation, project, or community
 * 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.
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting

 ## Our Responsibilities

-Project leaders are responsible for clarifying the standards of acceptable
+Project maintainers 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
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, 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 Moderators by tagging @community moderators. 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, @Mr. Certainly#0472 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.
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.

 ## 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.
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at support@adafruit.com. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.

 * `Adafruit CircuitPython <https://github.com/adafruit/circuitpython>`_
@ -28,32 +27,6 @@ Please ensure all dependencies are available on the CircuitPython filesystem.
 This is easily achieved by downloading
 `the Adafruit library and driver bundle <https://github.com/adafruit/Adafruit_CircuitPython_Bundle>`_.

-Installing from PyPI
--------------------
-
-On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally
-`from PyPI <https://pypi.org/project/adafruit-circuitpython-as726x/>`_. To install for
-current user:
-
-.. code-block:: shell
-
-    pip3 install adafruit-circuitpython-as726x
-
-To install system-wide (this may be required in some cases:
-
-.. code-block:: shell
-
-    sudo pip3 install adafruit-circuitpython-as726x
-
-To install in a virtual environment in your current project:
-
-.. code-block:: shell
-
-    mkdir project-name && cd project-name
-    python3 -m venv .env
-    source .env/bin/activate
-    pip3 install adafruit-circuitpython-as726x

 <https://github.com/adafruit/adafruit_CircuitPython_AS726x/blob/master/CODE_OF_CONDUCT.md>`_
 before contributing to help this project stay welcoming.

+Building locally
+================

-For information on building library documentation, please check out `this guide <https://learn.adafruit.com/creating-and-sharing-a-circuitpython-library/sharing-our-docs-on-readthedocs#sphinx-5-1>`_.
+Zip release files
+-----------------
+
+To build this library locally you'll need to install the
+`circuitpython-build-tools <https://github.com/adafruit/circuitpython-build-tools>`_ package.
+
+.. code-block:: shell
+
+    python3 -m venv .env
+    source .env/bin/activate
+    pip install circuitpython-build-tools
+
+Once installed, make sure you are in the virtual environment:
+
+.. code-block:: shell
+
+    source .env/bin/activate
+
+Then run the build:
+
+.. code-block:: shell
+
+    circuitpython-build-bundles --filename_prefix adafruit-circuitpython-as726x --library_location .
+
+Sphinx documentation
+-----------------------
+
+Sphinx is used to build the documentation based on rST files and comments in the code. First,
+install dependencies (feel free to reuse the virtual environment from above):
+
+.. code-block:: shell
+
+    python3 -m venv .env
+    source .env/bin/activate
+    pip install Sphinx sphinx-rtd-theme
+
+Now, once you have the virtual environment activated:
+
+.. code-block:: shell
+
+    cd docs
+    sphinx-build -E -W -b html . _build/html
+
+This will output the documentation to ``docs/_build/html``. Open the index.html in your browser to
+view them. It will also (due to -W) error out on any warning like Travis will. This is a good way to
+locally verify it will pass.
