+# Permissionless Software Foundation Community Contributing Guide 1.0
+
+This document describes a very simple process suitable for most projects under
+the PSF umbrella. It is based on [this Medium article](https://medium.com/the-node-js-collection/healthy-open-source-967fa8be7951) and the [Node.js Community Contribution Guide](https://github.com/nodejs/TSC/blob/master/BasePolicies/CONTRIBUTING.md).
+Projects are encouraged to adopt this whether they
+are hosted under the PSF or not.
+
+The goal of this document is to create a contribution process that:
+
+* Encourages new contributions.
+* Encourages contributors to remain involved.
+* Avoids unnecessary processes and bureaucracy whenever possible.
+* Creates a transparent decision making process which makes it clear how
+contributors can be involved in decision making.
+
+This document is based on much prior art in the Node.js community, io.js,
+and the Node.js project.
+
+Additional guidance can be found at the [Permissionless Software Foundation Telegram Channel](https://t.me/permissionless_software).
+
+## Vocabulary
+
+* A **Contributor** is any individual creating or commenting on an issue or pull request.
+* A **Committer** is a subset of contributors who have been given write access to the repository.
+* A **TC (Technical Committee)** is a group of committers representing the required technical
+expertise to resolve rare disputes.
+
+# Logging Issues
+
+Log an issue for any question or problem you might have. When in doubt, log an issue,
+any additional policies about what to include will be provided in the responses. The only
+exception is security disclosures which should be sent privately.
+
+Committers may direct you to another repository, ask for additional clarifications, and
+add appropriate metadata before the issue is addressed.
+
+Please be courteous, respectful, and every participant is expected to follow the
+project's Code of Conduct.
+
+# Contributions
+
+Any change to resources in this repository must be through pull requests. This applies to all changes
+to documentation, code, binary files, etc. Even long term committers and TC members must use
+pull requests.
+
+No pull request can be merged without being reviewed.
+
+For non-trivial contributions, pull requests should sit for at least 36 hours to ensure that
+contributors in other timezones have time to review. Consideration should also be given to
+weekends and other holiday periods to ensure active committers all have reasonable time to
+become involved in the discussion and review process if they wish.
+
+The default for each contribution is that it is accepted once no committer has an objection.
+During review committers may also request that a specific contributor who is most versed in a
+particular area gives a "LGTM" before the PR can be merged. There is no additional "sign off"
+process for contributions to land. Once all issues brought by committers are addressed it can
+be landed by any committer.
+
+In the case of an objection being raised in a pull request by another committer, all involved
+committers should seek to arrive at a consensus by way of addressing concerns being expressed
+by discussion, compromise on the proposed change, or withdrawal of the proposed change.
+
+If a contribution is controversial and committers cannot agree about how to get it to land
+or if it should land then it should be escalated to the TC. TC members should regularly
+discuss pending contributions in order to find a resolution. It is expected that only a
+small minority of issues be brought to the TC for resolution and that discussion and
+compromise among committers be the default resolution mechanism.
+
+# Becoming a Committer
+
+All contributors who land a non-trivial contribution should be on-boarded in a timely manner,
+and added as a committer, and be given write access to the repository.
+
+Committers are expected to follow this policy and continue to send pull requests, go through
+proper review, and have other committers merge their pull requests.
+
+# TC Process
+
+The TC uses a "consensus seeking" process for issues that are escalated to the TC.
+The group tries to find a resolution that has no open objections among TC members.
+If a consensus cannot be reached that has no objections then a majority wins vote
+is called. It is also expected that the majority of decisions made by the TC are via
+a consensus seeking process and that voting is only used as a last-resort.
+
+Resolution may involve returning the issue to committers with suggestions on how to
+move forward towards a consensus. It is not expected that a meeting of the TC
+will resolve all issues on its agenda during that meeting and may prefer to continue
+the discussion happening among the committers.
+
+Members can be added to the TC at any time. Any committer can nominate another committer
+to the TC and the TC uses its standard consensus seeking process to evaluate whether or
+not to add this new member. Members who do not participate consistently at the level of
+a majority of the other members are expected to resign.
