-Contributing to EssentialsX
-===========================
+# Contributing to EssentialsX

-Want to help improve EssentialsX? There are several ways you can support and contribute to the project.
+*By contributing to EssentialsX, you agree to license your changes under the [GNU General Public License version 3](https://github.com/EssentialsX/Essentials/blob/2.x/LICENSE).*

-If you'd like to make a financial contribution to the project, you can join our [Patreon](https://www.patreon.com/essentialsx/),
-or to make a one-off donation you can visit our [Ko-fi page](https://ko-fi.com/essentialsx). If you can't make a
-donation, don't worry! There are lots of other ways to contribute:
+## Submitting code changes to EssentialsX

-* Do you run a server? Take a look at our ["help wanted"](https://github.com/EssentialsX/Essentials/issues?q=is%3Aissue+is%3Aopen+sort%3Aupdated-desc+label%3A%22help+wanted%22)
-  and ["bug: unconfirmed"](https://github.com/EssentialsX/Essentials/issues?q=is%3Aissue+is%3Aopen+sort%3Aupdated-desc+label%3A%22bug%3A+unconfirmed%22)
-  issues, where you can find issues that need extra testing and investigation.
-* Do you speak multiple languages? If so, we always welcome contributions to our [Crowdin project](https://crowdin.com/project/essentialsx-official).
-* Do you enjoy helping others? If so, why not contribute to the [EssentialsX documentation](https://github.com/EssentialsX/wiki)?
-  You can also join the [MOSS Discord community](https://discord.gg/casfFyh) and provide direct community support to
-  other EssentialsX users.
-* If you're a developer, you could look through our ["open to PR"](https://github.com/EssentialsX/Essentials/issues?q=is%3Aissue+is%3Aopen+sort%3Aupdated-desc+label%3A%22status%3A+open+to+PR%22)
-  issues. We're always happy to receive bug fixes and feature additions as pull requests.
+If you're interested in submitting new code to EssentialsX, we accept changes via GitHub pull requests.

-Submitting a PR
---------------
+### Adding features

-EssentialsX has extensive templates for PRs that detail how to submit your PR. To find out more, see the PR templates for:
-* [Bug fixes](https://github.com/EssentialsX/Essentials/blob/2.x/.github/PULL_REQUEST_TEMPLATE/bug-fix.md) 
-* [New features](https://github.com/EssentialsX/Essentials/blob/2.x/.github/PULL_REQUEST_TEMPLATE/new-feature.md)
+In general, we will only consider PRs for features if they have already been discussed with the team through
+GitHub issues and discussions. Check the list of
+["open to PR" issues](https://github.com/EssentialsX/Essentials/issues?q=is%3Aissue+is%3Aopen+sort%3Aupdated-desc+label%3A%22status%3A+open+to+PR%22)
+and [feature request discussions](https://github.com/EssentialsX/Essentials/discussions/categories/ideas-and-feature-suggestions)
+before you start working on your changes. If you don't see your desired feature listed,
+[open a feature request](https://github.com/EssentialsX/Essentials/issues/new/choose) and wait for a response, otherwise
+you may end up wasting your time on a feature that we aren't in a position to accept.

-Want to discuss a feature before opening a PR? Join the [EssentialsX Development Discord server](https://discord.gg/CUN7qVb). Note that this server is **not for end-users** - if you need support with EssentialsX, you should join [MOSS](https://discord.gg/casfFyh) instead.
+#### Keep it focused

-By contributing to EssentialsX, you agree to license your code under the [GNU General Public License version 3](https://github.com/EssentialsX/Essentials/blob/2.x/LICENSE).
+Please try to keep feature PRs focused around one feature. Your PR should ideally contain
+one feature, or a few closely-linked features. If you submit several unrelated features 
+in one PR, the PR will not be accepted.
+
+### Fixing bugs
+
+If you're opening a PR to fix a bug, please ensure a bug report has been filed - search the
+[issue tracker](https://github.com/EssentialsX/Essentials/issues?q=is%3Aissue+is%3Aopen+sort%3Aupdated-desc+label%3A%22bug%3A+confirmed%22%2C%22bug%3A+unconfirmed%22%2C%22bug%3A+upstream%22)
+for an existing report, and if you can't find a bug report,
+[create one](https://github.com/EssentialsX/Essentials/issues/new/choose) before you submit your PR.
+
+#### Unconfirmed bugs
+
+You may find a bug report with the label `bug: unconfirmed`. This means the EssentialsX team hasn't had the time
+to review the bug report yet or hasn't been able to confirm
+whether the reported issue is actually a bug in EssentialsX. You can help us by following the steps in the report and
+posting whether you are able to replicate this issue, ideally on the latest versions of EssentialsX and Paper. This will
+help us confirm issues and prioritise PRs accordingly.
+
+#### Upstream bugs
+
+You may also find bug reports with the `bug: upstream` label. This label means the issue is caused by a bug in *another
+project*, not EssentialsX. This includes bugs in CraftBukkit/Spigot and bugs in other plugins. It may be appropriate to
+mitigate an issue in EssentialsX, but please check with us in the [EssentialsX Development Discord server](https://discord.gg/CUN7qVb) before you submit a PR.
+
+### Making your changes
+
+You'll need the following to make your changes to EssentialsX:
+
+* A GitHub account
+* [`git`](https://git-scm.com/downloads): the Git command-line tool, used to track and save your changes
+* [`gh`](https://cli.github.com/): the GitHub command-line tool, used to submit your changes to EssentialsX
+* Your IDE of choice - we recommend [IntelliJ IDEA Community Edition](https://www.jetbrains.com/idea/download)
+
+If you're already familiar with Git, you can skip this next section.
+
+You'll need to clone the EssentialsX repository
+(`gh repo clone EssentialsX/Essentials`), then create a new branch for your work
+(`cd Essentials` then `git switch -c my-cool-pr`).
+
+You can then make changes using your IDE of choice. Follow the instructions in `README.md` to build and test your
+changes.
+
+Once you've finished, you should commit your changes (`git commit -am "My cool commit name!"`).
+
+### Submitting your PR
+
+*Even if you're already familiar with GitHub, you will need to follow these steps in order to submit a PR to
+EssentialsX. This ensures we have the information we need to test and review your changes.*
+
+Next, you'll need to fork EssentialsX on GitHub and push your changes to a branch on that fork. We strongly recommend
+using the `gh` command-line tool for this:
+
+* In your terminal, run `gh pr create`.
+* Select either the bug fix or feature template, depending on what your PR is for.
+* If you get asked `Where should we push the '...' branch?`, select `Create a fork of EssentialsX/Essentials`.
+* For the title, choose a title that describes what your PR does. For example, `Add more ducks to /spawnmob`.
+* For the body, press E. You will then need to fill in the PR template in your text editor.
+  - Follow the instructions in the template and fill out the sections as required.
+  - This step is important! Without it, we won't know why you've made your changes or how to test them.
+* Save the file in your text editor and close it, then return to the terminal.
+* Select `Submit` to open your PR.
+
+If you follow these steps correctly, GitHub will create a fork (if necessary) and then open a PR with your changes. You
+can now sit back while we review your changes. If we need to ask questions or request further changes to your code,
+we will review your PR and post a comment on GitHub. You can respond to our reviews and comments on the GitHub website,
+and you can push new changes using `git commit` and `git push`.


+## Submitting community translations to EssentialsX
+
+EssentialsX relies on community translations for its messages in other languages. You can help translate EssentialsX on
+[Crowdin](https://translate.essentialsx.net/). You'll need a Crowdin account to translate and improve messages.
+
+If your language isn't listed or doesn't have an active proofreader, please let us know on Discord (see below).
+
+
+## Discussing EssentialsX contributions 
+
+Want to discuss something before opening a PR or translating messages? Join the
+[EssentialsX Development Discord server](https://discord.gg/CUN7qVb). Note that this server is **not for end-users** -
+if you need support with EssentialsX, you should join [MOSS](https://discord.gg/casfFyh) instead.

+     * This migration cleans up unused files left behind by the chaos resulting from Vault's questionable economy
+     * integration, and upstream Essentials' rushed and untested 1.7.10 UUID support.
+     * Both of these have been fixed in EssentialsX as of 2.18.x and 2.19.x respectively, but the leftover userdata
+     * files can reach into the tens of thousands and can cause excessive memory and storage usage, so this migration
+     * relocates these files to a backup folder to be removed by the server owner at a later date.
+     * <p>
+     * To quote JRoy, who suffered immensely while trying to debug and fix various related issues:
+     * <p>
+     * "Essentials decided when adding its initial support for UUIDs, it wanted an implementation which would cause
+     * eternal pain and suffering for any person who dared touch any of the code in the future. This code that was made
+     * was so bad, it managed to somehow not maintain any actual UUID support for any external integrations/plugins.
+     * Up until 2.19.0 and 2.18.0 respectively, our Vault integration and entire Economy system was entirely based off
+     * username strings, and thanks to Vault being a flawed standard, for some reason exposes account create to third
+     * party plugins rather than letting the implementation handle it. That doesn't seem like a huge problem at the
+     * surface, but there was one small problem: whoever made the Vault integration for Essentials suffered a stroke in
+     * the process of creating it. The implementation for the createAccount method, regardless of whether it was an
+     * actual player or an NPC account (which the Vault spec NEVER accounted for but plugins just have to guess when
+     * to support them), it would always create an NPC account. This caused any plugin integrating with Vault, creating
+     * NPC accounts for pretty much every single player on the server. It still, to this day, amazes me how nobody saw
+     * this code and didn't die without rewriting it; Or how everybody simply didn't stop using this plugin because how
+     * awful that godforsaken code was. Anyways, this upgrade does its best to delete NPC accounts created by the
+     * horrible economy code, as any operation which loads all user data into memory will load all these NPC accounts
+     * and spam the console with warnings."
