Remove over-engineered features:
- Remove identity show command
- Remove test file
- Simplify documentation
- Keep only essential init functionality

+## Example Workflow
+
+```bash
+# 1. Enable identity
+export MCPD_IDENTITY_ENABLED=true
+
+# 2. Create identity for your server
+mcpd identity init github-server --org "AcmeCorp"
+
+# 3. Start daemon - it will verify identity on startup
+mcpd daemon --dev
+# Look for: "Identity verified server=github-server"
+```
+
 ## Configuration
 
 Identity is disabled by default. Enable with:
-- Environment variable: `MCPD_IDENTITY_ENABLED=true`
+- Environment variable: `MCPD_IDENTITY_ENABLED=true`
+
+## Integration with .mcpd.toml
+
+While identity configuration isn't in the TOML file yet, servers with identities are automatically verified on startup when identity is enabled.
