+# Bamboo
+
+Bamboo connects your home network to a Blacktip edge over WireGuard. Websites and ports you open in Hammerhead can then reach Home Assistant, and any other device at home, without opening a port on your router. Bamboo only makes outbound connections.
+
+## Set up
+
+1. In Hammerhead, open **Sites**, choose **Add site**, and copy the site's token with **Show command**.
+2. Install this add-on and open its **Configuration** tab.
+3. Enter the **Hammerhead address** (for example `https://hammerhead.example.com`) and the **Site token**, then save.
+4. Start the add-on. The site shows as online in Hammerhead within a few seconds, and the add-on's log says `WireGuard up`.
+
+## Reach Home Assistant from the internet
+
+Add a resource in Hammerhead:
+
+* **What are you sharing:** Website
+* **Where does it point:** this site, host `127.0.0.1`, port `8123`
+* **How do people reach it:** your hostname, for example `home.example.com`
+
+Home Assistant refuses requests that come through a proxy unless it trusts the proxy. Bamboo connects from the same machine, so add this to `configuration.yaml` and restart Home Assistant:
+
+```yaml
+http:
+  use_x_forwarded_for: true
+  trusted_proxies:
+    - 127.0.0.1
+    - ::1
+```
+
+Without it, the page fails with "400: Bad Request". Home Assistant has its own sign-in, so you can leave the resource without a login in Hammerhead, or put one in front for a second layer.
+
+## Reach other devices at home
+
+The add-on uses host networking, so a resource can also point at any address on your network, such as a camera at `192.168.1.40`. Pick this site as the target and enter that address and port.
+
+## Updates
+
+The add-on version is the Bamboo release it installs. Update it from the add-on's page when a new version appears. Bamboo's own auto-update is not used here, because a new version arrives as an add-on update instead. Your WireGuard key and settings are kept across updates.
+
+## Troubleshooting
+
+* **The log asks for configuration:** the address or token is empty.
+* **The site stays offline:** check that the address opens in a browser from the same network, and that the token belongs to a site, not an edge.
+* **Home Assistant shows "400: Bad Request":** add the `http:` block above.
