-## TLS Interception
 
-jail automatically generates a Certificate Authority (CA) to intercept HTTPS traffic:
+# Using Makefile (recommended)
+make build
 
-- CA stored in `~/.config/jail/` (or `$XDG_CONFIG_HOME/jail/`)
-- CA certificate provided via `JAIL_CA_CERT` environment variable
-- Certificates generated on-demand for intercepted domains
-- CA expires after 1 year
-
-### Disable TLS Interception
-
-```bash
-jail --no-tls-intercept --allow "*" -- ./app
+# Or directly with Go
+go build -o jail .
 ```
