 A full-featured web dashboard for Hermes Agent. Manage AI chat sessions, monitor usage & costs, configure platform channels, schedule cron jobs, browse skills — all from a clean, responsive web interface.
 
+## Deployment
+
+This is a standalone Web UI app that does **not include** the Hermes Agent service. Install the official [Hermes Agent](https://github.com/1Panel-dev/appstore/tree/dev/apps/hermes-agent) from 1Panel app store first, then install this app to connect to your existing Agent.
+
+### Setup Steps
+
+1. Install **Hermes Agent** from 1Panel app store (official app)
+2. Install **Hermes Web UI** (this app)
+3. Configure the "Hermes Agent Gateway" URL during installation (default: `http://hermes-agent:8642`)
+4. If you changed the Agent container name, adjust the hostname in the gateway URL accordingly
+
+### Networking
+
+Both apps use the `1panel-network` and communicate via Docker internal networking — no additional ports need to be exposed.
