 # lazymc
 
-_Note: this is a prototype and currently incomplete._
-
 `lazymc` puts your Minecraft server to rest when idle, and wakes it up when
 players connect.
 
-Some Minecraft servers (especially modded) use an insane amount of
-resources when nobody is playing. `lazymc` helps with this by stopping your
-server when idle, until a player connects again.

+lazymc functions as proxy between clients and the server. It handles all
 incoming status connections until the server is started and then transparently
 proxies the rest.

+## Requirements
+
+- Linux, macOS (Windows not yet supported)
+- Minecraft Java Edition 1.6 or above
+
+Using a modded Minecraft server and client (such as Forge) should work fine.
+
+## Usage
+
+Make sure you meet all [requirements](#requirements).
+
+_Note: Installation options are limited at this moment. Read-to-go binaries will
+be published later. For now we compile and install from source._
+
+To compile and install you need Rust, install it through `rustup`: https://rustup.rs/
+
+When Rust is installed, compile and install `lazymc` from this git repository:
+
+```bash
+# Compile and install lazymc from source
+cargo install -f --git https://github.com/timvisee/lazymc
+
+# Ensure lazymc works
+lazymc --help
+```
+
+When `lazymc` is available, change into your server directory. Then set up the
+configuration and start it up:
+
+```bash
+# Change into your server directory
+cd server
+
+# Generate lazymc configuration
+lazymc config generate
+
+# Edit configuration
+# Set the correct server address, directory and start command
+nano lazymc.toml
+
+# Start lazymc
+lazymc start
+```
+
+Everything should now be running. Connect with your Minecraft client to wake
+your server up!
