+## Overview
+
+Secret Sources reads host passwords and keys from 1Password when you connect, instead of storing them in Termix.
+
+<br />
 
 ## 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.
+- Works with a self-hosted 1Password Connect server
+- Use `op://vault/item/field` references in a host's password or key fields
+- Secrets are fetched each time you connect and never stored in Termix

+## Support
 
-- 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.
