+# Secret Sources
+
+Fetch host secrets from 1Password when you connect instead of storing them in Termix.
+
+## Features
+
+- Connect a 1Password Connect server as a secret source.
+- Use `op://` references in a host's password or key fields instead of the secret itself.
+- Secrets are fetched each time you connect and are not stored in Termix.
+
+## Settings
+
+### Admin
+
+- Private endpoint allowlist: private or loopback hosts a secret source may reach, one per line. A self-hosted 1Password Connect server usually needs its address listed here.
+
+## Development
+
+```bash
+npm run build      # build into dist/
+npm run test       # run this plugin's tests
+npm run typecheck  # type-check this plugin
+```
+
+See `packages/plugin-sdk/ARCHITECTURE.md` for the plugin contract.
