-# Contributing to Ruffle
-
-🎉 Thanks for your interest in Ruffle! Contributions of all kinds are welcome.
-
-This document serves as a general guide for contributing to Ruffle. Follow your best judgement in following these guidelines.
-
-## Table of Contents
-
- * [Getting Started](#getting-started)
- * [Ways to Contribute](#ways-to-contribute)
-   * [Test your favorite Flash content](#test-your-favorite-flash-content)

- * [Reporting Bugs](#reporting-bugs)
- * [Code Guidelines](#code-guidelines)
- * [Commit Message Guidelines](#commit-guidelines)
- * [Pull Requests](#pull-requests)
-
-## Getting Started
-
-The [Ruffle wiki](https://github.com/ruffle-rs/ruffle/wiki) is a great way to familiarize yourself with the project. It contains info on how to building Ruffle, using Ruffle, and links to helpful documentation about the Flash format.
-
-Feel free to ask questions in our [Discord server](https://discord.gg/J8hgCQN).
-
-## Ways to Contribute
-
-We love new contributors! You can contribute to Ruffle in several ways:
-
-### Test your favorite Flash content
-
-Try out your favorite SWF content in Ruffle and see how it works! Follow the instructions on the [Using Ruffle](https://github.com/ruffle-rs/ruffle/wiki/Using-Ruffle) page to get Ruffle for your desired platform. You can run the SWF through the desktop player, the web demo, or try the extension on live websites.
-
-If you encounter specific issues with content, please follow the guidelines on filing an issue.
-
-### Improve documentation
-
-Improving documentation is a great way to learn the codebase. Adding documentation to both the wiki and the code eases the learning curve for both end users and new contributors.
-
-For documentation in the code, we follow the [rustdoc](https://doc.rust-lang.org/book/ch14-02-publishing-to-crates-io.html#making-useful-documentation-comments) guidelines.
-
-### Fix interesting issues
-
-Try your hand at fixing [issues that are interesting to you](https://github.com/ruffle-rs/ruffle/issues). Follow the instructions on [building Ruffle](https://github.com/ruffle-rs/ruffle/wiki/Building-Ruffle), familiarize yourself with the [project layout](https://github.com/ruffle-rs/ruffle/wiki/Project-Layout), and use [SWF resources and decompilers](https://github.com/ruffle-rs/ruffle/wiki/Helpful-Resources) to help debug the issue.
-
-You can also ask for mentoring on our [Discord server](https://discord.gg/J8hgCQN).
-
-### Implement missing Flash functionality
-
-Ruffle is a young project, and there is still much Flash functionality that is unimplemented. Check for the ["unimplemented"](https://github.com/ruffle-rs/ruffle/issues?q=is%3Aissue+is%3Aopen+label%3Aunimplemented) in issues.
-
-## Reporting bugs
-
-[Issue reports and feature requests](https://github.com/ruffle-rs/ruffle/issues) are encouraged, and are a great way to measure our progress!
-
-When filing an issue, if possible, please include:
-
- * A clear description of the problem
- * The platform you are testing on (web, desktop, OS)
- * A link/attachment to the SWF demonstrating the issue, if possible
- * Screenshots if the issue is a visible problem
-    * Bonus points for including the correct output from the official Flash Player
-
-These types of focused issues are helpful:
-
- * Tracking issues for specific Flash features (ActionScript 3.0, drawing API, etc.)
- * Bug reports for specific content that works but isn't quite right (art not looking correct, etc.)
- * Platform-specific issues
- * Enhancement requests to improve user experience
-
-The project is still in the early stages, so many Flash features are unimplemented and not yet expected to work. Please avoid filing generic issues such as:
-
- * A "this SWF doesn't work at all" report (what about it doesn't work?)
- * Duplicate issues for each piece of content using an unimplemented feature
- * Asking for dates when a feature will be implemented
-
-## Code Guidelines
-
-Ruffle is built using the latest stable version of the Rust compiler. Nightly and unstable features should be avoided.
-
-The Rust code in Ruffle strives to be idiomatic. The Rust compiler should emit no warnings when building the project. Additionally, all code should be formatted using [`rustfmt`](https://github.com/rust-lang/rustfmt) and linted using [`clippy`](https://github.com/rust-lang/rust-clippy). You can install these tools using `rustup`:
-
-```
-rustup component add rustfmt
-rustup component add clippy
-```
-
-You can auto-format your changes with `rustfmt`:
-
-`cargo run fmt --all`
-
-and you can run the clippy lints:
-
-`cargo clippy --all --tests`
-
-Specific warnings and clippy lints can be allowed when appropriate using attributes, such as:
-
-`#[allow(clippy::float_cmp)]`
-
-## Commit Message Guidelines
-
-Here is a sample commit message:
-
-`web: Fix incorrect rendering of gradients (close #23)`
-
- * If applicable, prefix the first line with a tag indicating the relevant area of changes:
-   * `core:`
-   * `desktop:`
-   * `web:`
-   * `avm1:`
-   * `docs:`
-   * `chore:`
- * Capitalize the first letter following the tag
- * Limit line length to 72 characters
- * Use the present tense and imperative mood ("fix", not "fixed" nor "fixes")
- * Reference any PRs or issues in the first line
- * Use keywords to close/address issues when applicable ("close #23")
- * Write more detailed info on following lines when applicable
-
-## Pull Requests
-
-Pull requests are the primary way to contribute code to Ruffle. Pull requests should be made against the latest `master` branch. Your pull request should not contain merges; you should always rebase when bringing the latest changes into your branch from the `master` branch. If there are merge conflicts, or if your commit history is messy, please rebase onto the latest master. [`git rebase -i`](https://thoughtbot.com/blog/git-interactive-rebase-squash-amend-rewriting-history#interactive-rebase) is a great way to clean up your pull request.
-
-When you make a pull request, our [CI](https://circleci.com/gh/ruffle-rs/ruffle) will build your changes and run them through all tests and style checks. All of these tests should pass before your pull request can be accepted. 
-
-One of [our regular contributors](https://github.com/orgs/ruffle-rs/people) will review your changes and try their best to helpfully suggest any changes. If all goes well, your PR should be merged without much delay. We use both standard merge commits and fast-forward merges depending on the size of the changes. Thanks for your contribution!
