+Contribution Guide
+==================
+You can make and publish your changes, and even suggest to merge your changes with main codebase of the server.
+
+Installing Dev Environment
+--------------------------
+ * First of all you need to clone main server code and some other parts, like Forge and Bukkit  
+   `git clone --recursive https://gitlab.prok.pw/Prototik/KCauldron.git`
+ * Move to `KCauldron` directory  
+   `cd KCauldron`
+ * Prepare some stuff  
+   `./gradlew setupCauldron`
+ * For now you need to open project in Eclipse IDE
+   * If you haven't Eclipse on your computer - [download and install it](https://www.eclipse.org/downloads/)  
+   * In Eclipse choose File - Import... - General - Existing Projects into Workspace, specify KCauldron/eclipse folder
+   * Unmark `Copy projects into workspace` button!
+   * Click Finish and start your contributing!
