 This simplicity-focused design approach allows us to make an efficient, low-overhead VPN protocol and minimize any potential attack surface.
 
+## Configuration
+
+Configurating the server and client are are relatively easy. Currently (since the project is in alpha), the configuration files **must be in the same directory as the working directory**.
+
+### Server
+ 
+"**server_config**" is a file that contains the server configuration, **one variable per line**. These are the current configuration available variables:
+
+- **SERVER_PUBLIC_KEY** (Hex String): The public key to be used
+- **SERVER_PRIVATE_KEY** (Hex String): The private key to be used
+
+**Example:**
+
+```
+SERVER_PUBLIC_KEY=787B648046F10DDD0B77A6303BE42D859AA65C52F5708CC3C58EB5691F217C7B

+"**whitelisted_keys**" is a file that **public keys of clients that are allowed to connect to the server, one key per line**.

 ## How does it work
 
 ColumnLynx makes use of both **TCP** and **UDP**. **TCP** is used for the initial handshake and commands, which **UDP** is used for actual packet transmission.
