+> ## Documentation for basically using Spawn module.
+
+## 1. For playing and running minecraft:
+
+#### 1.1 Download Spawn mod module.
+
+Visit **Spawn** repository on github, visit **releases** tab and download `.jar` files of latest _pre-release_ / release (**recommended**)
+
+Releases page: https://github.com/ProjectEssentials/ProjectEssentials-Spawn/releases
+
+#### 1.2 Install Spawn modification.
+
+The minecraft forge folder structure below will help you understand what is written below.
+
+```
+.
+├── assets
+├── config
+├── libraries
+├── mods (that's how it should be)
+│   ├── Project Essentials Spawn-1.14.4-1.X.X.X.jar
+│   ├── Project Essentials-1.14.4-1.X.X.X.jar.
+│   ├── Project Essentials Core-1.14.4-1.X.X.X.jar.
+│   └── Project Essentials Permissions-1.14.4-1.X.X.X.jar.
+└── ...
+```
+
+Place your mods and Spawn mods according to the structure above.
+
+#### 1.3 Verifying mod on the correct installation.
+
+Run the game, check the number of mods, if the list of mods contains `Project Essentials Spawn` mod, then the mod has successfully passed the initialization of the modification.
+
+After that, go into a single world, then try to write the `/spawn version` command, if you **get an error** that you do not have permissions, then the modification works as it should.
+
+#### 1.4 Control spawn via minecraft commands.
+
+We made the commands for you:
+
+```
+/spawn
+
