+If this plugin has helped you in any way, and you would like to return something back

+* Open a **pull request** containing a new feature or a bug fix, which you believe many users will benefit from.
+* Make detailed high-quality **bug reports**. The difference between a bug getting fixed in 1 week vs 1 hour 
+is in quality of the report (typically providing correct steps to reproduce that actually work).
+* Test **experimental builds**, which can be found in [GitHub Actions](https://github.com/NEZNAMY/TAB/actions) for problems of any kind including bugs. 
+This way you will help make the actual releases more stable / help get stable releases sooner.
+* Help improve the wiki by opening a [Wiki change issue](https://github.com/NEZNAMY/TAB/issues/new?assignees=&labels=Wiki&template=wiki_change.yml),

-# Distribution
-As of TAB 3.0.0, released with MC 1.18 (November 30th, 2021), there is no free / premium
-version anymore. Only one version of the plugin exists now, which contains all implemented features
-and is available to everyone for free. However, official support on discord is only provided to 
-those who have purchased the plugin.

 # Compiling

+# Documentation
+You can find everything about the plugin on the [Wiki](https://github.com/NEZNAMY/TAB/wiki). This includes a detailed description
+of all features, as well as information regarding compatibility or limitations of each feature.  
 
 # Issues
-The [Issues](https://github.com/NEZNAMY/TAB/issues) section is **only** available for **bug reports**
-or other issues which are not directly a bug (performance issues, errors, etc.).
-Support is provided on discord and feature requests are currently not accepted due to high demand and
-being busy with bug reports, which take priority over new features. 
-We are not looking to add any new major features anymore. 
-We would rather spend time improving existing features instead.  
-  
-When opening a bug report, make sure you provide all necessary information to reproduce the bug,
-otherwise we will not able to fix it. Saying "it only occurs randomly" or "I don't know how to 
-reproduce it" has no value and cannot be converted into actual code.
+The [Issues](https://github.com/NEZNAMY/TAB/issues) section is an issue tracker for all the kind of problems covered in issue templates.
+Please refrain from attempting to use it to receive help with your server, such issues will be closed immediately.  
+When opening an issue, provide as much information as possible. The difference between a bug getting fixed in 1 week vs 1 hour
+is in quality of the report. Bug reports where steps to reproduce are "idk" have no value and will not help to get the bug fixed at all.
