+# Headplane Agent
+
+The Headplane agent is a lightweight service that runs alongside the Headscale server.
+It's used to interface with devices on your network locally, unlocking the following:
+
+- **Node Information/Status**: View Tailscale versions, OS versions, and connection details.
+- **SSH via Web (Soon)**: Connect to devices via SSH directly from the Headplane UI.
+
+It's built on top of [tsnet](https://tailscale.com/kb/1244/tsnet), the official
+set of libraries published by Tailscale for creating local services that can
+join the tailnet.
+While it isn't required to run the agent, it's highly recommended to get the
+closest experience to the SaaS version of Tailscale. This is paired with the
+integrations provided by Headplane to manage DNS and Headscale settings.
+
+### Installation
+The agent can either be ran as a standalone binary or as a Docker container.
+Agent binaries are available on the [releases](https://github.com/tale/headplane/releases) page.
+The Docker image is available through the `ghcr.io/tale/headplane-agent` tag.
+
+The agent requires the following environment variables to be set:
+- **`HP_AGENT_HOSTNAME`**: A hostname you want to use for the agent.
+- **`HP_AGENT_TS_SERVER`**: The URL to your Headscale instance.
+- **`HP_AGENT_TS_AUTHKEY`**: An authorization key to authenticate with Headscale (see below).
+- **`HP_AGENT_HP_SERVER`**: The URL to your Headplane instance.
+- **`HP_AGENT_HP_AUTHKEY`**: The generated auth key to authenticate with Headplane.
+
+If you already have Headplane setup, you can generate all of these values within
+the Headplane UI. Navigate to the `Settings` page and click `Agent` to get started.
