+# Cistech Tunnel - Build Files
+
+This directory contains the Dockerfile and scripts to build the OpenConnect-SSO VPN Docker image.
+
+## Files
+
+- `Dockerfile` - Docker image definition (Ubuntu 22.04 + openconnect-sso + noVNC)
+- `build.sh` - Build and push script
+- `scripts/entrypoint.sh` - Container entrypoint
+
+## Building
+
+```bash
+cd /etc/runtipi/repos/runtipi/apps/cistech-tunnel/build
+./build.sh
+```
+
+This builds and pushes to `git.alexzaw.dev/alexz/openconnect-vpn:latest`
+
+To build without pushing:
+```bash
+docker build -t git.alexzaw.dev/alexz/openconnect-vpn:latest .
+```
+
+## What's in the image
+
+The Dockerfile creates an image with:
+- Ubuntu 22.04
+- openconnect + openconnect-sso[full] (Python)
+- Playwright Chromium browser (for SSO authentication)
+- TigerVNC server + noVNC (web-based VNC)
+- Tools: oathtool (TOTP), openbox, xterm
+
+### Scripts (baked in)
+- `/opt/scripts/startup-vnc.sh` - Starts VNC server and noVNC
+- `/opt/scripts/entrypoint.sh` - Container entrypoint (DNS fix, IP forwarding, config generation)
+
+## Runtime mounts (from shared/)
+
+When running as cistech-tunnel app, these are mounted from `shared/`:
+- `/shared/openconnect-vpn` - Main VPN connection script
+- `/shared/xstartup` -> `/root/.vnc/xstartup` - VNC session startup
+
+## Environment Variables
+
+| Variable | Description |
+|----------|-------------|
+| `VPN_EMAIL` | Email/username for SSO login |
+| `VPN_PASSWORD` | Password for SSO login |
+| `VPN_TOTP_SECRET` | TOTP secret for 2FA (base32) |
+| `VPN_HOST` | VPN server URL (e.g., `https://vpn.example.com/Group`) |
+| `TARGET_IP` | Target IP for connectivity testing |
+| `VNC_PASSWORD` | VNC access password |
+
+## Ports
+
+- `5901` - VNC server
+- `6092` - noVNC web interface
+
+## How it works
+
+1. Container starts, generates openconnect-sso config from env vars
+2. VNC server starts with noVNC web interface
+3. xterm launches with the `openconnect-vpn` script
+4. Script sets up keyring with credentials (password + TOTP)
+5. openconnect-sso handles SSO authentication via hidden browser
+6. VPN connects and IP forwarding/NAT is configured
