-This plugin can be used to pre-generate the region of a world around the spawn chunk.
+<div align="center">
+<h1>This plugin isn't actively developed anymore. If you want to add features feel free to fork it and implement it yourself or use <a href="https://www.spigotmc.org/resources/chunky.81534/">Chunky</a> instead.</h1>
+</div>
+
+This plugin can be used to pre-generate the region of a world around the spawn chunk(s).
 The generation automatically pauses when a player joins the server (assuming the server was empty before)
 and resumes when the server is empty again. The generation also auto-resumes after a server
 restart. The plugin tracks the ticks per second and pauses the generation when the tps
 is lower than 2 (configurable).
 
-## Commands
+## Built with
+
+- [Gradle](https://gradle.org/) - Dependency Management and Build Tool
+- [Sqlite JDBC](https://bitbucket.org/xerial/sqlite-jdbc/) - Database Driver for JDBC
+- [bStats](https://bstats.org/) - Statistical Insights
+
+## Features
+
+- Pregeneration of a specific area around the world center
+- Configuration of world centers
+- Integration into dynmap
+- Teleportation to chunks
+- Auto-Pause/Resume on player join/leave
+- Highly configurable
+
+## Installing
+
+Just download the jar from the latest release and place it into the servers plugins folder.
+
+## Usage and Configuration
+
+### Commands
 
 All features can be accessed with the command `/chunkmaster` or the aliases `/chm`, `chunkm`, `cmaster`.
 
-- `/chunkmaster generate [world] [chunk count] [unit]` Starts the generation until the specified chunk count or the world border is reached.
+- `/chunkmaster generate [world] [radius] [<square|circle>]` Starts the generation until the specified chunk count or the world border is reached.
 - `/chunkmaster list` Lists all running generation tasks
-- `/chunkmaster cancel <Task id>` Cancels the generation task with the specified id (if it is running).
+- `/chunkmaster cancel <Task id|world name>` Cancels the generation task with the specified id (if it is running).
 - `/chunkmaster pause` Pauses all generation tasks until the resume command is executed.
 - `/chunkmaster resume` Resumes all paused generation tasks.
 - `/chunkmaster reload` Reloads the configuration file.
 - `/chunkmaster tpchunk <X> <Z>` Teleports you to the specified chunk coordinates.
+- `/<command> setCenter [[<world>] <chunkX> <chunkZ>]]` - sets the center chunk of the world
+- `/<command> getCenter [<world>]` - returns the center chunk of the world
+- `/<command> stats [<world>]` - returns the stats of the server or a specific world
+

+**Generate a 100 chunks * 100 blocks square around the center:**
+
+`/chm generate [world] 50`

-## Spigot and Paper
+### Spigot and Paper
 
 The plugin works on spigot and paper servers but is significantly faster on paper servers
 (because it profits from asynchronous chunk loading an the better implementation of the
 isChunkGenerated method).
+
+## Translation
+
+The **Mandarin** translation is provided by [NPBeta](https://github.com/NPBeta) and
+was validated by [ed3d3d](https://twitter.com/ed3d3d).
+
+The **French** translation is provided by [Corenb](https://github.com/Corenb) and
+was validated by [Fiwel00](https://github.com/Fiwel00) and [Youssef Habri](https://github.com/youssefhabri).
+
+The **German** and **English** translation is provided by me.
+You can translate the plugin yourself and start a PR to this repository to add it to the
+provided translation.
+
+1. create an i18n folder in the plugins folder (plugins/Chunkmaster)
+2. copy the [default translations file](https://github.com/Trivernis/spigot-chunkmaster/blob/master/src/main/resources/i18n/DEFAULT.i18n.properties) 
+into the newly created folder and rename it to <language-abbrevation>.i18n.properties
+3. modify the values in the file for your translation (you can use minecraft § formatting sequences)
+4. set the language property in the config file to your language abbrevation
+5. start the plugin
+
+Now you should see your translation being used by the plugin for localized messages.
