 ## Creating an Issue
 - If you are reporting a bug:
- - **make sure that you are using the latest supported version** before opening an issue.
- - **test it on a clean test server, WITHOUT PLUGINS**, to see if the issue still occurs. If not then it may be a plugin issue. Please also indicate the result of such tests.
-
-- [Search the issue tracker](https://github.com/pmmp/PocketMine-MP/issues?utf8=%E2%9C%93&q=is%3Aissue) to check if anyone has already reported it, to avoid needlessly creating duplicate issues. Make sure you also check closed issues, as an issue you think is valid may already have been resolved.
-
-- If your issue is related to a plugin, **do not report here, contact the plugin's original author** instead.

-
 - **No generic titles** such as "Question", "Help", "Crash Report" etc. A good issue report provides a quick summary in the title. If you just got a crash report but you don't understand it, please look for a line starting with `Message`. It summarizes the bug.
-

 - To express appreciation, objection, confusion or other supported reactions on pull requests, issues or comments on them, use GitHub [reactions](https://github.com/blog/2119-add-reactions-to-pull-requests-issues-and-comments) rather than posting an individual comment with an emoji only. This helps keeping the issue/pull request conversation clean and readable.

 - If your issue is related to the PocketMine-MP website, forums, etc., please [talk to a human directly](README.md#discussion).
 
 
 
-## Contributing Code
-- To contribute code to the repository, [fork it on GitHub](https://github.com/pmmp/PocketMine-MP/fork), create a branch on your fork, and make your changes on your fork. You can then make a [pull request](https://github.com/pmmp/PocketMine-MP/pull/new) to the project to compare your branch to ours and propose your changes to our repository. We use the Pull Request system to allow members of the team to review changes before they are merged.

+### Licensing
+By proposing a pull request to the project, you agree to your code being distributed within PocketMine-MP under the [LGPL license](LICENSE).
 
-- At PocketMine, **we enforce a very high standard for contributions**. This is because PocketMine-MP and its related projects are used very widely in production. While this might seem like we are being mean at times, **our priority is what is best for PocketMine-MP itself**. We try to ensure that our project's codebase is as clean as possible and ensure that only top-quality material makes it through to PocketMine-MP itself. **If a contribution does not live up to our standards, changes may be requested or the pull request may be closed.**
-
-- **Your pull request will be checked and discussed in due time.** Since the team is scattered all around the world, your PR may not receive any attention for some time.
-
-- **Avoid using GitHub Web Editor**. The web editor lacks most useful GIT features and **should only be used for very minor changes**. It is immediately clear if the web editor has been used, and if so the PR is more likely to be rejected. If you want to make serious contributions, **please learn how to use [GIT version control](https://git-scm.com/)**.
-
-- **Do not copy-paste code**. There are potential license issues implicit with copy-pasting, and copy-paste usually indicates a lack of understanding of the actual code. Copy-pasted code is obvious a mile off and **any PR like this is likely to be closed**. If you want to use somebody else's code from a Git repository, **use [GIT's cherry-pick feature](https://git-scm.com/docs/git-cherry-pick)** to cherry-pick the commit. **Cherry-picking is the politer way to copy somebody's changes** and retains all the original accreditation, so there is no need for copy-pasted commits with descriptions like `Some code, thanks @exampleperson`.
-
-- In addition to the above, **make sure you can explain your changes**. If you can't provide a good explanation of changes, your PR may be rejected.
+### Contribution standards
+- **We enforce a very high standard for contributions**. This is because PocketMine-MP and its related projects are used very widely in production. While this might seem like we are being mean at times, **our priority is what is best for PocketMine-MP itself**.
+We try to ensure that our project's codebase is as clean as possible and ensure that only top-quality material makes it through to PocketMine-MP itself.
+- **If a contribution does not meet our standards, changes may be requested or the pull request may be closed.**
 
+### Pull requests
 - **Create a new branch for each pull request.** Do not create a pull request with commits that exist in another pull request.
-
-- **Code should use the same style as in PocketMine-MP.** See [below](#code-syntax) for an example.
-
-- **The code must be clear** and written in English, comments included.
-
 - **Use descriptive commit titles.** You can see an example [here](http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html).
-
-- **Try to stick to one change per commit.** This ensures that if you create a PR with several changes, we can decide which ones we wish to include and which ones not to include.
-
-- **It is inadvisable to create pull requests with large commits** unless this has been discussed with the team beforehand. Large pull requests are difficult to review, and such pull requests may end up being closed. The only exception is when all features in the pull request are related to each other, and share the same core changes.
-
+- **Do not include multiple unrelated changes in one commit.** An atomic style for commits is preferred - this means that changes included in a commit should be part of a single distinct change set. See [this link](https://www.freshconsulting.com/atomic-commits/) for more information on atomic commits. See the [documentation on `git add`](https://git-scm.com/docs/git-add) for information on how to isolate local changes for committing.
+- **Your pull request will be checked and discussed in due time.** Since the team is scattered all around the world, your PR may not receive any attention for some time.
+- **It is inadvisable to create large pull requests with lots of changes** unless this has been discussed with the team beforehand. Large pull requests are difficult to review, and such pull requests may end up being closed. The only exception is when all features in the pull request are related to each other, and share the same core changes.
 - **You may be asked to rebase your pull request** if the branch becomes outdated and/or if possibly conflicting changes are made to the target branch. To see how to do this, read [this page](https://github.com/edx/edx-platform/wiki/How-to-Rebase-a-Pull-Request).
+- **Details should be provided of tests done.** Simply saying "Tested" or equivalent is not acceptable.
