 # Sanke
 A simple snake game in the terminal. No third party libraries needed.
 
-## Demo
-Click image for video
+# Compiling
+Run:
+```sh
+compile.sh release
+```
+to compile an optimized build. The script creates a directory called 'target' that contains the executable.
 
-[![Sanke demo](https://img.youtube.com/vi/_coOVAW9qa4/0.jpg)](https://www.youtube.com/watch?v=_coOVAW9qa4)
+See:
+```sh
+compile.sh help
+```
+for more.
 
-## How it works
+# Running
+Run:
+```sh
+sanke 
+```
+to play with defaults settings.
+
+See:
+```sh
+sanke --help
+```
+for setting game options.
+
+# How it works
 The program makes the terminal use non-canonical input and output by using termios. Then it updates and prints a 2D character array containing the board borders, snake, and food. Before terminating, the program restores canonical mode.
 
-## Info
+# Info
 Only tested with the combination of
 - GCC
 - Linux
