+## Command Line Flags
+
+Redlib supports the following command line flags:
+
+- `-4`, `--ipv4-only`: Listen on IPv4 only.
+- `-6`, `--ipv6-only`: Listen on IPv6 only.
+- `-r`, `--redirect-https`: Redirect all HTTP requests to HTTPS (no longer functional).
+- `-a`, `--address <ADDRESS>`: Sets address to listen on. Default is `[::]`.
+- `-p`, `--port <PORT>`: Port to listen on. Default is `8080`.
+- `-H`, `--hsts <EXPIRE_TIME>`: HSTS header to tell browsers that this site should only be accessed over HTTPS. Default is `604800`.
+
 ## Instance settings
 
 Assign a default value for each instance-specific setting by passing environment variables to Redlib in the format `REDLIB_{X}`. Replace `{X}` with the setting name (see list below) in capital letters.
