+# 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
+* Discussion or promotion of activities or projects that intend or pose a risk of
+  significant harm
+* 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.
+
+## 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 email <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
+any Community Moderator.
+
+Email and direct message reports will be kept confidential.
+
+In situations on Discord where the issue is particularly offensive, possibly
+illegal, requires immediate action, or violates the Discord terms of service,
+you should also report the message directly to [Discord](https://discord.com/safety).
+
+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
+   CircuitPython Community Code of Conduct. All reports will be reviewed and
+   investigated.
+2. If the behavior is a severe 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.
+6. Disciplinary actions (warnings, bans, etc) for Code of Conduct violations apply
+   to the platform where the violation occurred. However, depending on the severity
+   of the violation, the disciplinary action may be applied across Adafruit's other
+   community platforms. For example, a severe violation on the Adafruit Discord
+   server may result in a ban on not only the Adafruit Discord server, but also on
+   the Adafruit GitHub organisation, Adafruit Forums, Adafruit Twitter, etc.
+
+## 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](https://www.contributor-covenant.org/),
+version 1.4, available on [contributor-covenant.org](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.

+
+Using Creative Commons Public Licenses
+
+Creative Commons public licenses provide a standard set of terms and conditions
+that creators and other rights holders may use to share original works of
+authorship and other material subject to copyright and certain other rights
+specified in the public license below. The following considerations are for
+informational purposes only, are not exhaustive, and do not form part of our
+licenses.
+
+Considerations for licensors: Our public licenses are intended for use by
+those authorized to give the public permission to use material in ways otherwise
+restricted by copyright and certain other rights. Our licenses are irrevocable.
+Licensors should read and understand the terms and conditions of the license
+they choose before applying it. Licensors should also secure all rights necessary
+before applying our licenses so that the public can reuse the material as
+expected. Licensors should clearly mark any material not subject to the license.
+This includes other CC-licensed material, or material used under an exception
+or limitation to copyright. More considerations for licensors : wiki.creativecommons.org/Considerations_for_licensors
+
+Considerations for the public: By using one of our public licenses, a licensor
+grants the public permission to use the licensed material under specified
+terms and conditions. If the licensor's permission is not necessary for any
+reason–for example, because of any applicable exception or limitation to copyright–then
+that use is not regulated by the license. Our licenses grant only permissions
+under copyright and certain other rights that a licensor has authority to
+grant. Use of the licensed material may still be restricted for other reasons,
+including because others have copyright or other rights in the material. A
+licensor may make special requests, such as asking that all changes be marked
+or described. Although not required by our licenses, you are encouraged to
+respect those requests where reasonable. More considerations for the public
+: wiki.creativecommons.org/Considerations_for_licensees Creative Commons Attribution
+4.0 International Public License
+
+By exercising the Licensed Rights (defined below), You accept and agree to
+be bound by the terms and conditions of this Creative Commons Attribution
+4.0 International Public License ("Public License"). To the extent this Public
+License may be interpreted as a contract, You are granted the Licensed Rights
+in consideration of Your acceptance of these terms and conditions, and the
+Licensor grants You such rights in consideration of benefits the Licensor
+receives from making the Licensed Material available under these terms and
+conditions.
+
+Section 1 – Definitions.
+
+a. Adapted Material means material subject to Copyright and Similar Rights
+that is derived from or based upon the Licensed Material and in which the
+Licensed Material is translated, altered, arranged, transformed, or otherwise
+modified in a manner requiring permission under the Copyright and Similar
+Rights held by the Licensor. For purposes of this Public License, where the
+Licensed Material is a musical work, performance, or sound recording, Adapted
+Material is always produced where the Licensed Material is synched in timed
+relation with a moving image.
+
+b. Adapter's License means the license You apply to Your Copyright and Similar
+Rights in Your contributions to Adapted Material in accordance with the terms
+and conditions of this Public License.
+
+c. Copyright and Similar Rights means copyright and/or similar rights closely
+related to copyright including, without limitation, performance, broadcast,
+sound recording, and Sui Generis Database Rights, without regard to how the
+rights are labeled or categorized. For purposes of this Public License, the
+rights specified in Section 2(b)(1)-(2) are not Copyright and Similar Rights.
+
+d. Effective Technological Measures means those measures that, in the absence
+of proper authority, may not be circumvented under laws fulfilling obligations
+under Article 11 of the WIPO Copyright Treaty adopted on December 20, 1996,
+and/or similar international agreements.
+
+e. Exceptions and Limitations means fair use, fair dealing, and/or any other
+exception or limitation to Copyright and Similar Rights that applies to Your
+use of the Licensed Material.
+
+f. Licensed Material means the artistic or literary work, database, or other
+material to which the Licensor applied this Public License.
+
+g. Licensed Rights means the rights granted to You subject to the terms and
+conditions of this Public License, which are limited to all Copyright and
+Similar Rights that apply to Your use of the Licensed Material and that the
+Licensor has authority to license.
+
+h. Licensor means the individual(s) or entity(ies) granting rights under this
+Public License.
+
+i. Share means to provide material to the public by any means or process that
+requires permission under the Licensed Rights, such as reproduction, public
+display, public performance, distribution, dissemination, communication, or
+importation, and to make material available to the public including in ways
+that members of the public may access the material from a place and at a time
+individually chosen by them.
+
+j. Sui Generis Database Rights means rights other than copyright resulting
+from Directive 96/9/EC of the European Parliament and of the Council of 11
+March 1996 on the legal protection of databases, as amended and/or succeeded,
+as well as other essentially equivalent rights anywhere in the world.
+
+k. You means the individual or entity exercising the Licensed Rights under
+this Public License. Your has a corresponding meaning.
+
+Section 2 – Scope.
+
+   a. License grant.
+
+1. Subject to the terms and conditions of this Public License, the Licensor
+hereby grants You a worldwide, royalty-free, non-sublicensable, non-exclusive,
+irrevocable license to exercise the Licensed Rights in the Licensed Material
+to:
+
+         A. reproduce and Share the Licensed Material, in whole or in part; and
+
+         B. produce, reproduce, and Share Adapted Material.
+
+2. Exceptions and Limitations. For the avoidance of doubt, where Exceptions
+and Limitations apply to Your use, this Public License does not apply, and
+You do not need to comply with its terms and conditions.
+
+      3. Term. The term of this Public License is specified in Section 6(a).
+
+4. Media and formats; technical modifications allowed. The Licensor authorizes
+You to exercise the Licensed Rights in all media and formats whether now known
+or hereafter created, and to make technical modifications necessary to do
+so. The Licensor waives and/or agrees not to assert any right or authority
+to forbid You from making technical modifications necessary to exercise the
+Licensed Rights, including technical modifications necessary to circumvent
+Effective Technological Measures. For purposes of this Public License, simply
+making modifications authorized by this Section 2(a)(4) never produces Adapted
+Material.
+
+      5. Downstream recipients.
+
+A. Offer from the Licensor – Licensed Material. Every recipient of the Licensed
+Material automatically receives an offer from the Licensor to exercise the
+Licensed Rights under the terms and conditions of this Public License.
+
+B. No downstream restrictions. You may not offer or impose any additional
+or different terms or conditions on, or apply any Effective Technological
+Measures to, the Licensed Material if doing so restricts exercise of the Licensed
+Rights by any recipient of the Licensed Material.
+
+6. No endorsement. Nothing in this Public License constitutes or may be construed
+as permission to assert or imply that You are, or that Your use of the Licensed
+Material is, connected with, or sponsored, endorsed, or granted official status
+by, the Licensor or others designated to receive attribution as provided in
+Section 3(a)(1)(A)(i).
+
+   b. Other rights.
+
+1. Moral rights, such as the right of integrity, are not licensed under this
+Public License, nor are publicity, privacy, and/or other similar personality
+rights; however, to the extent possible, the Licensor waives and/or agrees
+not to assert any such rights held by the Licensor to the limited extent necessary
+to allow You to exercise the Licensed Rights, but not otherwise.
+
+2. Patent and trademark rights are not licensed under this Public License.
+
+3. To the extent possible, the Licensor waives any right to collect royalties
+from You for the exercise of the Licensed Rights, whether directly or through
+a collecting society under any voluntary or waivable statutory or compulsory
+licensing scheme. In all other cases the Licensor expressly reserves any right
+to collect such royalties.
+
+Section 3 – License Conditions.
+
+Your exercise of the Licensed Rights is expressly made subject to the following
+conditions.
+
+   a. Attribution.
+
+1. If You Share the Licensed Material (including in modified form), You must:
+
+A. retain the following if it is supplied by the Licensor with the Licensed
+Material:
+
+i. identification of the creator(s) of the Licensed Material and any others
+designated to receive attribution, in any reasonable manner requested by the
+Licensor (including by pseudonym if designated);
+
+            ii. a copyright notice;
+
+            iii. a notice that refers to this Public License;
+
+            iv. a notice that refers to the disclaimer of warranties;
+
+v. a URI or hyperlink to the Licensed Material to the extent reasonably practicable;
+
+B. indicate if You modified the Licensed Material and retain an indication
+of any previous modifications; and
+
+C. indicate the Licensed Material is licensed under this Public License, and
+include the text of, or the URI or hyperlink to, this Public License.
+
+2. You may satisfy the conditions in Section 3(a)(1) in any reasonable manner
+based on the medium, means, and context in which You Share the Licensed Material.
+For example, it may be reasonable to satisfy the conditions by providing a
+URI or hyperlink to a resource that includes the required information.
+
+3. If requested by the Licensor, You must remove any of the information required
+by Section 3(a)(1)(A) to the extent reasonably practicable.
+
+4. If You Share Adapted Material You produce, the Adapter's License You apply
+must not prevent recipients of the Adapted Material from complying with this
+Public License.
+
+Section 4 – Sui Generis Database Rights.
+
+Where the Licensed Rights include Sui Generis Database Rights that apply to
+Your use of the Licensed Material:
+
+a. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract,
+reuse, reproduce, and Share all or a substantial portion of the contents of
+the database;
+
+b. if You include all or a substantial portion of the database contents in
+a database in which You have Sui Generis Database Rights, then the database
+in which You have Sui Generis Database Rights (but not its individual contents)
+is Adapted Material; and
+
+c. You must comply with the conditions in Section 3(a) if You Share all or
+a substantial portion of the contents of the database.
+
+For the avoidance of doubt, this Section 4 supplements and does not replace
+Your obligations under this Public License where the Licensed Rights include
+other Copyright and Similar Rights.
+
+Section 5 – Disclaimer of Warranties and Limitation of Liability.
+
+a. Unless otherwise separately undertaken by the Licensor, to the extent possible,
+the Licensor offers the Licensed Material as-is and as-available, and makes
+no representations or warranties of any kind concerning the Licensed Material,
+whether express, implied, statutory, or other. This includes, without limitation,
+warranties of title, merchantability, fitness for a particular purpose, non-infringement,
+absence of latent or other defects, accuracy, or the presence or absence of
+errors, whether or not known or discoverable. Where disclaimers of warranties
+are not allowed in full or in part, this disclaimer may not apply to You.
+
+b. To the extent possible, in no event will the Licensor be liable to You
+on any legal theory (including, without limitation, negligence) or otherwise
+for any direct, special, indirect, incidental, consequential, punitive, exemplary,
+or other losses, costs, expenses, or damages arising out of this Public License
+or use of the Licensed Material, even if the Licensor has been advised of
+the possibility of such losses, costs, expenses, or damages. Where a limitation
+of liability is not allowed in full or in part, this limitation may not apply
+to You.
+
+c. The disclaimer of warranties and limitation of liability provided above
+shall be interpreted in a manner that, to the extent possible, most closely
+approximates an absolute disclaimer and waiver of all liability.
+
+Section 6 – Term and Termination.
+
+a. This Public License applies for the term of the Copyright and Similar Rights
+licensed here. However, if You fail to comply with this Public License, then
+Your rights under this Public License terminate automatically.
+
+b. Where Your right to use the Licensed Material has terminated under Section
+6(a), it reinstates:
+
+1. automatically as of the date the violation is cured, provided it is cured
+within 30 days of Your discovery of the violation; or
+
+      2. upon express reinstatement by the Licensor.
+
+c. For the avoidance of doubt, this Section 6(b) does not affect any right
+the Licensor may have to seek remedies for Your violations of this Public
+License.
+
+d. For the avoidance of doubt, the Licensor may also offer the Licensed Material
+under separate terms or conditions or stop distributing the Licensed Material
+at any time; however, doing so will not terminate this Public License.
+
+   e. Sections 1, 5, 6, 7, and 8 survive termination of this Public License.
+
+Section 7 – Other Terms and Conditions.
+
+a. The Licensor shall not be bound by any additional or different terms or
+conditions communicated by You unless expressly agreed.
+
+b. Any arrangements, understandings, or agreements regarding the Licensed
+Material not stated herein are separate from and independent of the terms
+and conditions of this Public License.
+
+Section 8 – Interpretation.
+
+a. For the avoidance of doubt, this Public License does not, and shall not
+be interpreted to, reduce, limit, restrict, or impose conditions on any use
+of the Licensed Material that could lawfully be made without permission under
+this Public License.
+
+b. To the extent possible, if any provision of this Public License is deemed
+unenforceable, it shall be automatically reformed to the minimum extent necessary
+to make it enforceable. If the provision cannot be reformed, it shall be severed
+from this Public License without affecting the enforceability of the remaining
+terms and conditions.
+
+c. No term or condition of this Public License will be waived and no failure
+to comply consented to unless expressly agreed to by the Licensor.
+
+d. Nothing in this Public License constitutes or may be interpreted as a limitation
+upon, or waiver of, any privileges and immunities that apply to the Licensor
+or You, including from the legal processes of any jurisdiction or authority.
+
+Creative Commons is not a party to its public licenses. Notwithstanding, Creative

+Please ensure all dependencies are available on the CircuitPython filesystem.
+This is easily achieved by downloading
+`the Adafruit library and driver bundle <https://circuitpython.org/libraries>`_
+or individual libraries can be installed using
+`circup <https://github.com/adafruit/circup>`_.
+
+.. todo:: Describe the Adafruit product this library works with. For PCBs, you can also add the
+image from the assets folder in the PCB's GitHub repo.
+
+`Purchase one from the Adafruit shop <http://www.adafruit.com/products/>`_
+Installing from PyPI
+=====================
+.. note:: This library is not available on PyPI yet. Install documentation is included
+   as a standard element. Stay tuned for PyPI availability!
+
+.. todo:: Remove the above note if PyPI version is/will be available at time of release.
+
+On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally `from
+PyPI <https://pypi.org/project/adafruit-circuitpython-spd1656/>`_.
