+If this plugin has helped you in any way, and you would like to return something back 
+to make the plugin even better, there is a lot of ways to contribute:  
+* 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), 
+where you can improve existing descriptions, add information you found missing, fix typos / grammar mistakes or add more examples.

-## Introduction  
-Here it is. After countless requests to go opensource, I did it to make those people quiet. It worked.  
-It's already been a year and I still can't see any positives of it. This way I just made it easier for everyone to make a plugin as good, so people can stop using it and switch to something better. 
-  
-  
-## Compiling
-Plugin can be compiled using maven.
+# About
+TAB aims to be a superior all-in-one minecraft plugin for displaying information that outperforms all 
+similar plugins in terms of features, performance and compatibility.  
+More information can be found at [Why TAB?](https://github.com/NEZNAMY/TAB/wiki/Why-TAB%3F) wiki page.

+ * Scoreboard implementation for Bukkit, which uses packets
+ * to send scoreboards. While md_5 keeps saying that you don't
+ * need packets for scoreboards in every single spigot update,
+ * this is not true. It may seem that way at first, but after
+ * investigating, fatal problems are found:<p>
+ * #1 - Limitations on legacy versions are forced in the API.
+ *      While this may not seem like a problem, it enforces those
+ *      limits even for 1.13+ players (if using ViaVersion).<p>
+ * #2 - Modern versions no longer have any limits, but md_5
+ *      decided to add some random limits for absolutely no reason
+ *      at all. Scoreboard title received a random 128 characters
+ *      limit including color codes. Together with the almighty bukkit
+ *      RGB format using 14 characters for 1 color code, this makes
+ *      gradients just impossible to use. Team prefix/suffix also
+ *      received a 64 characters limit (excluding color codes at least),
+ *      however that might not be enough for displaying a line of text
+ *      in sidebar, which would require splitting the text into prefix
+ *      and suffix, which is just begging for bugs to be introduced.<p>
+ * #3 - Other plugins can decide to put players into their own
+ *      scoreboard, automatically destroying all visuals made by the
+ *      plugin. They might also put all players into the same scoreboard,
+ *      making per-player view of teams, especially sidebar not working.<p>
