 ## 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 unwelcome sexual attention or

+
+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

+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.
 
 ## 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. Examples of
+when an individual is representing the project or its community. As a community
-representing a project or community include using an official project e-mail
+member, you are representing our community, and are expected to behave
-address, posting via an official social media account, or acting as an appointed
+accordingly.
-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.

-
-.. 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:

-
-    circuitpython-build-bundles --filename_prefix adafruit-circuitpython-bmp280 --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.
