+# Minetest server
+
+Image to run a Minetest server. Listen on port 30000.
+
+## Configuration
+The Minetest server configuration is defined on a `minetest.conf` file.
+
+### Mounted volumes
+To have persistent data and configuration, you should mount some volumes on your host system :
+- `/root/.minetest/minetest.conf` : Minetest configuration file
+- `/root/.minetest/worlds` : Minetest maps
+- `/root/.minetest/textures` : Minetest textures
+
+### Log levels
+To set the log level of your container, you can use the `LOGLEVEL` environment variable.
+- 1 : Print to console errors only
+- 2 : Print more information to console
+- 3 : Print even more information to console
+- 4 : Print enormous amounts of information to log and console
+
+Default (and recommended) level is 1.
