-# Contributing
+# Contributing Guidelines
+We welcome everyone to contribute towards the PlaceholderAPI Project, but doing so will require you to follow specific rules to keep a consistent and welcoming way of contributing.

-When contributing to this repository, please first discuss the change you wish to make via [issue] or through [Discord] with the owners of this repository before making a change. 
+If you have any questions about contributions towards the project, feel free to contact us on our [Discord Server][discord].

-Please note we have a code of conduct, please follow it in all your interactions with the project.
+## Issues
+Like any other project can you encounter bugs or a feature is missing for you in the plugin.  
+For that, you can open an [issue] to report a bug, or suggest a new feature to be added.

-## Pull Request Process
+When doing so, make sure you follow rules below:

-1. Update the README.md with details of changes if it is affected by those changes.
-2. Try to prevent any breaking changes affecting the end-user (Developers using the API).  
-Mention any breaking changes that could affect the end-user.
-3. Document any public methods that the end-user might use.
+### Follow the template
+We have issue templates to help us get the required information more easily. Please follow the provided template when either filing a bug report or feature request.  
+Your issue may be closed without warning for not following the template.
+
+### Use the latest version
+When it comes to bug reports should you always check first, that you're using the latest release of PlaceholderAPI.  
+Often the bug you've encountered, is fixed in a newer version.
+
+The same rules apply when making a feature request.
+
+### No duplicate issue
+Make sure that there aren't any existing issues relating to the problem, which are still open, or are closed with a solution/explanation.  
+Opening a separate issue for a bug report or feature request, that already exists on the issue tracker only slows down the process of fixing the bug or implementing the feature.
+
+If an issue with the bug or feature you want to report/suggest exists, comment on it with your info (bug reports) or give it a :thumbsup: (Feature Request) to show that this is important for you.
+
+### Issue isn't caused by external source
+PlaceholderAPI provides a feature to have expansions (separate jar files) for placeholders. This gives it a possability that an issue you encounter is caused by said expansions or a separate plugin that uses those expansions.  
+In those cases should you report the issue to the issue tracker of the expansion or plugin.
+
+## Pull requests
+As an open source project are we welcoming all contributions to improve PlaceholderAPI, being it changes to its code like bug fixes or new features, or contributions to its documentation such as the [Wiki] or the Javadoc.
+
+### Code contributions
+Any contributions to PlaceholderAPI's code should be done towards the [`development`][dev] branch. Targeting the `master` branch in your Pull request may get it closed without warning.  
+Additionally should you follow the project's codestyle which you can find in the [`config/style`][style] directory.
+
+### Wiki/Javadoc contributions
+If your pull request only targets the [wiki] or only changes the javadoc comments of PlaceholderAPI (And not its actual code), it should be to `docs/wiki` branch.  
+The develop branch should only be targeted when you also change some of PlaceholderAPI's code.

+## Code of Conduct
+
+### Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
+
+### Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+### 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
+
+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
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team on their [discord server][discord]. All
+complaints will be reviewed and investigated and will result in a response that is deemed necessary and 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.
+
+### Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at [http://contributor-covenant.org/version/1/4][version]

 Here are frequently asked questions about stuff related to PlaceholderAPI.

-## It only shows %placeholder% and not the variable
-Make sure, that you've tried the following steps:
- PlaceholderAPI is installed and running (Shows green in `/pl` and responds to the `/papi` command)
- You downloaded the expansion with `/papi ecloud download [expansion]`  
-A list of available expansions and their placeholders can be found [[here|Placeholders]]!  
-Also note that not all placeholders are in a seperate expansion. Some are "hardcoded" into a plugin.
- You reloaded PlaceholderAPI with `/papi reload` after downloading an expansion.
- Any possible dependency for the expansion (Plugin) is installed and running.
- The placeholder doesn't contain any typos.
- The plugin that should use the placeholder actually supports PlaceholderAPI.
-For a list of plugins supporting PlaceholderAPI go [[here|Plugins-using-PlaceholderAPI]].
+## It only shows `%placeholder%` and not the variable
+When a plugin or `/papi parse me %placeholder%` only returns the placeholder itself and no value should you check for the following things:
+
+### The expansion is actually installed.
+In many cases is the cause that the expansion of the placeholder is missing.  
+Just execute `/papi ecloud download <name of expansion>` followed by `/papi reload` to activate it. You can find a list of Expansions and their Placeholders [[on this page|Placeholders]].
+
+**NOTE!**  
+Not all placeholders come in their own expansion. Some plugins *hardcode* them in and load them on startup, when hooking into PlaceholderAPI.
+
+### Plugin actualls supports PlaceholderAPI
+It can happen that the plugin you use to display the placeholder in doesn't support PlaceholderAPI. In such a case check, if the parse command returns the actual value of a placeholder.  
+If that is the case while the plugin is still displaying the placeholder, can this be an indicator of the plugin not supporting PlaceholderAPI.
+
+You can find a list of plugins supporting PlaceholderAPI [[here|Plugins-using-PlaceholderAPI]].  
+Just make sure that "Supports placeholders" has a check mark in front of it.
+
+### No typo in the placeholder
+Double-check that the placeholder you set doesn't contain a typo. You can use `/papi ecloud placeholders <expansion>` (replace `<expansion>` with the name of the expansion) to get a list of all the placeholders the expansion may have.  
+Keep in mind that this only works for separate expansions on the eCloud and not for those that are loaded by plugins.
+
+### Plugin is enabled
+If an expansion depends on a plugin, make sure you have the plugin installed and that it is enabled (Shows green in `/pl`).

 ## I can't download the expansion
 Make sure, that the connection to the cloud (https://api.extendedclip.com) isn't blocked by a firewall or similar.

 If both checks failed, go to the cloud-page and download the jar manually. Put it then in the `expansions` folder of PlaceholderAPI (`/plugins/PlaceholderAPI/expansions`)

+You sure can!  
+We welcome contributions to our wiki by everyone. If you found a typo or want to improve this wiki in another way, head over to the [Wiki's readme file][readme] to find out about how you can contribute towards this wiki.

+## PlaceholderAPI is posting an error about an outdated expansion?
+```
+[00:00:01 ERROR]: [PlaceholderAPI] Failed to load Expansion class <expansion> (Is a dependency missing?)
+[00:00:01 ERROR]: [PlaceholderAPI] Cause: NoClassDefFoundError <path>
+```
+
+If you receive the above error, try to do the following steps:
+
+- Make sure any required dependency of the mentioned expansion (e.g. a plugin) is installed.
+- Make sure you use the latest version supported for the server version you use.
+- If you downloaded the jar from the ecloud, make sure it isn't malformed/corrupted.
+
+If the issue persists after you've done those checks, report it to the author of the expansion.  
+In most cases is the issue that either a dependency is missing or that the expansion tries to use outdated methods from PlaceholderAPI.

 ## Adding your resource(s)
-If you have one or multiple resources that support PlaceholderAPI (being it by just supporting placeholders from other plugins, or providing your own) can you add them to the wiki in the following ways.
+When you either have a plugin, which adds and/or uses placeholders or an expansion and you want to add it to the wiki should you follow the below steps.
+
+- [Plugins using PlaceholderAPI](#plugins-using-placeholderapi)
+- [Placeholders](#placeholders)

 ### [Plugins using PlaceholderAPI]
-You should always add your resource to this page, no matter if it only supports placeholders or also provides its own.
+This is only required for plugins.  
+If your plugin supports placeholders of other plugins and/or provides own placeholders through PlaceholderAPI should you always add it the the `Plugins using PlaceholderAPI` page.

-The format of a plugin is always as follows:
-```md
+Each entry on this page follows a specific format that you need to follow:  
+```markdown
 - **[:name](:url)**
  - [?] Supports placeholders.
  - [?] Provides own placeholders. [:link]
 ```

-A quick summary over the different parts:
-
- `:name` is the name of your resource. The resources are ordered by alphabet and if yours has the same name as another one listed, add it __below__ the other resource.
- `:url` should be replaced with a URL to your resource page (Spigot, dev.bukkit, etc.). If you use Spigot, make sure to remove any text after the `/resources/` and only leave the ID. For example will https://www.spigotmc.org/resources/placeholderapi.6245/ become https://www.spigotmc.org/resources/6245/.  
-If you don't have your resource on any resource page can you either ommit the URL (Just provide the name) or provide a link to its source, if available.
- `?` should be replaced with either an `x` or a space depending on wether your plugin supports the option or not. So the `[?]` becomes either `[x]` or `[ ]`
- `:link` depends on wether your plugin provides own placeholders or not. If it doesn't, then you can just give `Link`. If it does provide placeholders, make sure to provide `[[Link|Placeholders#:name]]` where `:name` would be the name of your resource in the [Placeholders] page.

+| `:url`  | The URL to your plugin. Spigot URLs should only contain the ID. E.g. https://www.spigotmc.org/resources/placeholderapi.6245/ becomes https://www.spigotmc.org/resources/6245/            |
+| `?`     | Should be replaced with either an `x` or a space, depending on if the option is supported. So the result is either `[x]` or `[ ]`                                                        |
+| `:link` | If your plugin also provides own placeholders should you add it to the [Placeholders] page. In such a case should you use `[**[[Link\|Placeholders#:name]]**]` otherwhise just `[Link]` |

 ### [Placeholders]
-If your plugin provides its own placeholders through an extension is it recommendet to add this extension to the [Placeholders] page.  
+This step is required if you either have a plugin or an expansion that provides their own placeholders. You should add your resource to the Placeholders page of the wiki.  
 This page is split up into two sections: PAPI Placeholders and Plugin Placeholders.

 PAPI Placeholders are extensions that don't require an external plugin or other dependency to function normally. Common examples are the Player or Server extensions.  
 The Plugin Placeholders are extensions that require a plugin or other dependency to function. They are often used to provide values from one pluging (e.g. Vault) to another plugin through the help of PlaceholderAPI.

-If your extension is build into your resource can you just set `NO DOWNLOAD COMMAND` instead.

-Always keep an empty line in between the `----` and the next entry below it.  
-If your extension is at the very bottom of the page can you ommit the `----`.
+#### Extra notes

-You will also need to add your extension's name to the list at the very top in the format `- **[:name](#:name)**` where `:name` is the extension name.
+- If your entry has another one below it will you need to add an empty line, followed by for hypthons (`----`) at the bottom of your entry to separate it.
+- You are allowed to add a description between the `> :command` and the placeholder list. Keep in mind to keep an empty line after the command line to prevent wrong formatting. A description is only useful/required if your expansion/plugin offers specific placeholder values and/or features.
+- Always add your entry's name to the list at the top of the page in the format `- [:name](#:name)`. Note that if your entry shares the same name as another one on the page and you added it below it, that you will need to append a `-1`, `-2`, ... to the name in the brackets, depending on how many entries with the same name there are.

+----
 ## Other Wiki pages
 Please follow these general guidelines when editing any other pages.

-### Linking
-Linking should always be done through either the reference option or through the Wiki link option.  
-When the link leads to a page on the wiki should you use either `[[:page]]` or `[[:name|:page]]` where `:page` would be the name of the Wiki page (Case sensitive) and `:name` the text that would be displayed instead.  
-When linking to a section within a Wiki page should you link to it using a hashtag (`#`). For example would linking to the player extension result in `[[Placeholders#player]]` (Always have the section lowercase.  
-However, when you link to a section in the same wiki page should you do it in the format `[:name](#:section)` where `:name` is the text to display and `:section` is the name of the section.
+### Links
+The wiki uses 3 types of links:

+- [Reference Links](#reference-links)
+- [Wiki Links](#wiki-links)
+- [Header Links](#header-links)

-When you link to an external page that isn't part of the wiki should you do it as a reference link (Exception is the above mentioned cases for resources and extensions).  
-You do this by adding `[:name]: :url` at the top of the page where `:name` is the reference name to use and `:url` is the url to link to.
+#### Reference Links
+Reference Links are in the format `[:text]: :url` where `:text` is the name to use as reference and `:url` is the url.  
+These types of links are usually put at the top of the page and allow us easier updating of these links, by just altering the URL without the need to replace them in the entire file.

-You can then just use either `[:name]` or `[:display_text][:name]` to link to the url you set (`:display_text` could be any text (including spaces) to display).  
-Reference links are case-insensitive.
+To use a reference link, either use `[:text]` or `[:displayed_text][:text]` to link with a differently shown text.

-This system allows us to easly maintain the links without the need to update a URL on several places within the page.
+For example: With `[wiki]: https://github.com/PlaceholderAPI/PlaceholderAPI/wiki` will `[wiki]` become [wiki] and `[to the wiki][wiki]` becomes [to the wiki][wiki].

+Always use reference links for URLs that point outside of the Wiki. Only exceptions are Links in the [Placeholders] and [Plugins using PlaceholderAPI] page (See above for details).
+
+#### Wiki Links
+Wiki links are used to link to other pages on the wiki.  
+These types of links are in the format `[[:pagename]]` or `[[:text|:pagename]]` to display a different text. `:pagename` is case-sensitive.
+
+If you want to link to a header in another wiki page can you use `[[:text|:pagename#:header]]`.
+
+#### Header Links
+Header links are used to link to a section within the same wiki page.  
+The format is `[:text](#:header)`. The header name is case-insensitive but it's recommended to keep it lowercase.
+
+----
 ### Lists
 Lists should always be started with a hyphen (`-`) to better distinguish it from other formatting characters like the asterisk (`*`) used for bold or italic text.
