 If you would like to contribute to Parity Ethereum, please **fork it**, fix bugs or implement features, and [propose a pull request](https://github.com/paritytech/parity-ethereum/compare).
 
-Please, refer to the [Coding Guide](https://wiki.parity.io/Coding-guide) in our wiki for more details about hacking on Parity.
+### Labels & Milestones
+
+We use [labels](https://github.com/paritytech/parity-ethereum/labels) to manage PRs and issues and communicate state of a PR. Please familiarize yourself with them. Furthermore we are organizing issues in [milestones](https://github.com/paritytech/parity-ethereum/milestones). Best way to get started is to a pick a ticket from the current milestone tagged [`easy`](https://github.com/paritytech/parity-ethereum/labels/Q2-easy%20%F0%9F%92%83) and get going or [`mentor`](https://github.com/paritytech/parity-ethereum/labels/Q1-mentor%20%F0%9F%95%BA) and get in contact with the mentor offering their support on that larger task.
+
+### Rules
+
+There are a few basic ground-rules for contributors (including the maintainer(s) of the project):
+
+* **No `--force` pushes** or modifying the master branch 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, and include the associated issue ID (if any) in the branch name.
+* **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 [house coding style](https://wiki.parity.io/Coding-guide).
+
+### Merge Process
+
+Merging pull requests once CI is successful:
+
+* A PR needs to be reviewed and approved by project maintainers unless:
+  * it does not alter any logic (e.g. comments, dependencies, docs), then it may be tagged [`insubstantial`](https://github.com/paritytech/parity-ethereum/pulls?q=is%3Aopen+is%3Apr+label%3A%22A2-insubstantial+%F0%9F%91%B6%22) and merged by its author once CI is complete.
+  * it is an urgent fix with no large change to logic, then it may be merged after a non-author contributor has approved the review once CI is complete.
+
+* Once a PR is ready for review please add the [`pleasereview`](https://github.com/paritytech/parity-ethereum/pulls?utf8=%E2%9C%93&q=is%3Aopen+is%3Apr+label%3A%22A0-pleasereview+%F0%9F%A4%93%22+) label. Generally PRs should sit with this label for 48 hours in order to garner feedback. It may be merged before if all relevant parties had a look at it.
+* 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 behavior.
+* Undue maintenance burden.
+* Breaking with house coding style.
+* Pessimization (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.

+### Viewing documentation for Parity Ethereum packages
+

+
+### Contributing to documentation for Parity Ethereum packages
+
+[Document source code](https://doc.rust-lang.org/1.9.0/book/documentation.html) for Parity Ethereum packages by annotating the source code with documentation comments.
+
+Example (generic):
+```markdown
+/// Summary
+///
+/// Description
+///
+/// # Panics
+///
+/// # Errors
+///
+/// # Safety
+///
+/// # Examples
+///
+/// Summary of Example 1
+///
+/// ```rust
+/// // insert example 1 code here
+/// ```
+///
+```
+
+* Important notes:
+  * Documentation comments must use annotations with a triple slash `///`
+  * Modules are documented using `//!`
+```
+//! Summary (of module)
+//!
+//! Description (of module)
+```
+* Special section header is indicated with a hash `#`.
+  * `Panics` section requires an explanation if the function triggers a panic
+  * `Errors` section is for describing conditions under which a function of method returns `Err(E)` if it returns a `Result<T, E>`
+  * `Safety` section requires an explanation if the function is `unsafe`
+  * `Examples` section includes examples of using the function or method
+* Code block annotations for examples are included between triple graves, as shown above.
+Instead of including the programming language to use for syntax highlighting as the annotation
+after the triple graves, alternative annotations include the `ignore`, `text`, `should_panic`, or `no_run`.
+* Summary sentence is a short high level single sentence of its functionality
+* Description paragraph is for details additional to the summary sentence
+* Missing documentation annotations may be used to identify where to generate warnings with `#![warn(missing_docs)]`
+or errors `#![deny(missing_docs)]`
+* Hide documentation for items with `#[doc(hidden)]`
+
+### Contributing to documentation (tests, extended examples, macros) for Parity Ethereum packages
+
+The code block annotations in the `# Example` section may be used as [documentation as tests and for extended examples](https://doc.rust-lang.org/1.9.0/book/documentation.html#documentation-as-tests).
+
+* Important notes:
+  * Rustdoc will automatically add a `main()` wrapper around the code block to test it
+  * [Documenting macros](https://doc.rust-lang.org/1.9.0/book/documentation.html#documenting-macros).
+  * Documentation as tests examples are included when running `cargo test`
