 ### Development
 - Run the server with `cargo run` or `RUST_LOG=debug cargo run` to run with debug.
 ### Production
-- Run the binary with `minh_cord {LOCAL_IP_ADDRESS}`.
+- Run the binary with `./minh_cord`.
 
 ## Connecting to the server
-- Get your local IP address of the machine you're running the server on: i.e `192.168.0.100`
 - Run the server with the above commands.
-- Run `telnet 192.168.0.100` from a client to connect to the server.
+- Run `telnet {SERVER_INTERNAL_IP_ADDRESS}` from a client to connect to the server.
