-# chunkmaster [![CircleCI](https://circleci.com/gh/Trivernis/spigot-chunkmaster.svg?style=svg)](https://circleci.com/gh/Trivernis/spigot-chunkmaster)
-
-This plugin can be used to pre-generate the region of a world around the spawn chunk.
-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
-
-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 list` Lists all running generation tasks
-- `/chunkmaster cancel <Task id>` 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.
-
-## Config
-
-```yaml
-generation:
-
-  # The maximum amount of chunks that are loaded before unloading and saving them.
-  # Higher values mean higher generation speed but greater memory usage.
-  # The value should be a positive integer.
-  max-loaded-chunks: 10
-
-  # Paper Only
-  # The maximum amount of requested chunks with the asynchronous paper chunk
-  # loading method. Higher values mean faster generation but more memory usage
-  # (and probably bigger performance impact).
-  # The value should be a positive integer.
-  max-pending-chunks: 10
-
-  # The period (in ticks) in which a generation step is run.
-  # Higher values mean less performance impact but slower generation.
-  # The value should be a positive integer.
-  period: 2
-
-  # The max amount of chunks that should be generated per step.
-  # Higher values mean higher generation speed but higher performance impact.
-  # The value should be a positive integer.
-  chunks-per-step: 4
-
-  # Paper Only
-  # The number of already generated chunks that will be skipped for each step.
-  # Notice that these still have a performance impact because the server needs to check
-  # if the chunk is generated.
-  # Higher values mean faster generation but greater performance impact.
-  # The value should be a positive integer.
-  chunk-skips-per-step: 100
-
-  # The maximum milliseconds per tick the server is allowed to have
-  # during the cunk generation process.
-  # If the mspt is greather than this, the chunk generation task pauses.
-  # The value should be a positive integer greater than 50.  
-  mspt-pause-threshold: 500
-
-  # If the chunk generation process should pause on player join.
-  # Notice that playing on a server that constantly generates chunks can be
-  # very laggy and can cause it to crash.
-  # You could configure the values above so that the performance impact of the generation
-  # process is minimal.
-  # The value should be a boolean <true/false>
-  pause-on-join: true
-```
-
-## 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).

+<div align="center">

+</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).
+
+## 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] [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|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
+
+#### Examples
+**Generate a 100 chunks * 100 blocks square around the center:**
+
+`/chm generate [world] 50`
+
+**Generate a circle with a radius of 100 blocks around the center:**
+
+`/chm generate [world] 100 circle`
+
+### Config
+
+```yaml
+
+# The language settings.
+# Supported out of the box are german (de) and english (en).
+# Additional languages can be configured in the plugins folder under i18n.
+# The file name must be in the format <language>.i18n.properties and the content

+
+# Actiates/deactivates the dynmap integration.
+# With the setting set to 'true' the plugin tries to trigger the rendering
+# of generated chunks right before unloading them. It also adds an area
+# marker to the dynmap to show the area that will be pregenerated.
+# The marker is removed automatically when the task is finished or canceled.
+# The value should be a boolean <true/false>

+  # Paper Only
+  # The maximum amount of requested chunks with the asynchronous paper chunk

+  mspt-pause-threshold: 500
+
+  # The period in ticks for how often loaded chunks get unloaded.
+  # Unloading happens in the main thread and can impact the server performance.
+  # You can tweak this setting with the max-loaded-chunks setting to have either
+  # a lot of chunks unloaded at once or fewer chunks unloaded more often.
+  # If the maximum number of loaded chunks is reached the generation pauses until the
+  # unloading task runs again so keep that in mind.
+  # The value should be a positive integer.

+## 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.
