 # CircuitPython 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 CircuitPython 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 the project maintainer.
 Email reports will be kept confidential.
 In situations on GitHub where the issue is particularly offensive, possibly
 illegal, requires immediate action, or violates the GitHub terms of service,
 you should also report the message directly to GitHub via the comment, or via
 [GitHub Support](https://support.github.com/contact/report-abuse?category=report-abuse&report=other&report_type=unspecified).
 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 CircuitPython's
   other community platforms. For example, a severe violation in one Community forum
   may result in a ban on not only the CircuitPython GitHub organisation,
   but also on the CircuitPython Twitter, live stream text chats, etc.
 ## Scope
 This Code of Conduct and the enforcement policies listed above apply to all
 CircuitPython Community venues. This includes but is not limited to any community
 spaces (both public and private), and CircuitPython repositories. Examples of
 CircuitPython Community spaces include but are not limited to meet-ups, issue
 threads on GitHub, text chats during a live stream, 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
 [Adafruit Community Code of Conduct](https://github.com/adafruit/Adafruit_Community_Code_of_Conduct),
 which 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 CircuitPython 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.

 ("Creative Commons") is not a law firm and does not provide legal services
 or legal advice. Distribution of Creative Commons public licenses does not
 create a lawyer-client or other relationship. Creative Commons makes its licenses
 and related information available on an "as-is" basis. Creative Commons gives
 no warranties regarding its licenses, any material licensed under their terms
 and conditions, or any related information. Creative Commons disclaims all
 liability for damages resulting from their use to the fullest extent possible.
 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.
