+=== Facilitation, Not Strongarming
 
 We recognise that this software is merely a tool for users to create and maintain their blockchain of preference. We see that blockchains are naturally community platforms with users being the ultimate decision makers. We assert that good software will maximise user agency by facilitate user-expression on the network. As such:
 
 * This project will strive to give users as much choice as is both reasonable and possible over what protocol they adhere to; but
 * use of the project's technical forums, commenting systems, pull requests and issue trackers as a means to express individual protocol preferences is forbidden.
 
-## Our Responsibilities
+== Our Responsibilities
 
 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 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 contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
 
-## Scope
+== Scope
 
 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 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
+== Enforcement
 
 Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at admin@parity.io. The project team will review and investigate all complaints, and will respond in a way that it deems 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.

+
+`Substrate` projects is a **OPENISH Open Source Project**
+
+== What?
+
+Individuals making significant and valuable contributions are given commit-access to a project to contribute as they see fit. A project is more like an open wiki than a standard guarded open source project.
+
+== Rules
+
+There are a few basic ground-rules for contributors (including the maintainer(s) of the project):
+
+. **No `--force` pushes** or modifying the Git history in any way. If you need to rebase, ensure you do it in your own repo.
+. **Non-master branches**, prefixed with a short name moniker (e.g. `gav-my-feature`) must be used for ongoing work.
+. **All modifications** must be made in a **pull-request** to solicit feedback from other contributors.
+. A pull-request *must not be merged until CI* has finished successfully.
+. Contributors should adhere to the https://github.com/paritytech/polkadot/wiki/Style-Guide[house coding style].
+
+Merging pull requests once CI is successful:
+
+. A pull request that does not alter any logic (e.g. comments, dependencies, docs) may be tagged https://github.com/paritytech/substrate/pulls?utf8=%E2%9C%93&q=is%3Apr+is%3Aopen+label%3AA2-insubstantial[`insubstantial`] and merged by its author.
+. A pull request with no large change to logic that is an urgent fix may be merged after a non-author contributor has reviewed it well.
+. All other PRs should sit for 48 hours with the https://github.com/paritytech/substrate/pulls?q=is%3Apr+is%3Aopen+label%3AA0-pleasereview[`pleasereview`] tag in order to garner feedback.
+. No PR should be merged until all reviews' comments are addressed.
+
+.Reviewing pull requests:
+When reviewing a pull request, the end-goal is to suggest useful changes to the author. Reviews should finish with approval unless there are issues that would result in:
+
+. Buggy behaviour.
+. Undue maintenance burden.
+. Breaking with house coding style.
+. Pessimisation (i.e. reduction of speed as measured in the projects benchmarks).
+. Feature reduction (i.e. it removes some aspect of functionality that a significant minority of users rely on).
+. Uselessness (i.e. it does not strictly add a feature or fix a known issue).
+
+.Reviews may not be used as an effective veto for a PR because:
+. There exists a somewhat cleaner/better/faster way of accomplishing the same feature/fix.
+. It does not fit well with some other contributors' longer-term vision for the project.
+
+== Releases
+
+Declaring formal releases remains the prerogative of the project maintainer(s).
+
+== Changes to this arrangement
+
+This is an experiment and feedback is welcome! This document may also be subject to pull-requests or changes by contributors where you believe you have something valuable to add or change.
+
+== Heritage
+
+These contributing guidelines are modified from the "OPEN Open Source Project" guidelines for the Level project: https://github.com/Level/community/blob/master/CONTRIBUTING.md
