 # Dungeon-game
 Dungeon style game made with sfml
 
-## Dependecies
-g++\
-Make\
-Sfml
+## Building
 
-## Screenshots
+### Dependecies
+- g++
+- Make
+- Sfml-lib
+- MinGW (for building Windows exe)
+
+### Linux
+After installing the `sfml` package for your distribution, the application can be compiled with the `make` command.
+
+### Windows (For Windows on Linux)
+After installing the `MinGW` set of compilers, a release can be built using the `make release PLATFORM=win64` command. Note that the first time this command is executed, it will download the MinGW version of SFML from the internet.
+
+## Usage
+### Linux
+After compiling, the application can be started using `make run`.
