+# Immich Public Proxy
+
+Immich is a wonderful bit of software, but since it holds all your private photos it's best to keep it fully locked down.
+This presents a problem when you want to share a photo or a gallery with someone.
+
+**Immich Public Proxy** provides a barrier of security between the public and Immich, and _only_ allows through requests 
+which you have publicly shared. When it receives a valid request, it talks to Immich locally via API and returns only
+those shared images.
+
+It exposes no ports, allows no incoming data, and has no API to exploit.
+
+The ideal setup is to have Immich secured privately behind VPN or mTLS, and only allow public access to Immich Public Proxy.
+
+## How to install
+
+1. Clone the repo:
+
+```bash
+git clone https://github.com/alangrainger/immich-public-proxy.git
+```
+
+2. Create a `.env` file to configure the app.
+
+```
+IMMICH_URL=http://localhost:2283
+API_KEY="Get this from your Immich Account Settings page"
+SERVER_URL=https://shared.example.com
+SERVER_PORT=3000
+```
+
+- `IMMICH_URL` is the URL to access Immich in your local network. This is not your public URL.
+- `SERVER_URL` will be the public URL for accessing this Immich Public Proxy app.
+
+3. Start the docker container:
+
+```bash
+docker-compose up -d
+```
+
+4. Set the same `SERVER_URL` as your "External domain" in your Immich **Server Settings**:
+
+<img src="public/images/server-settings.png" width="418" height="205">
+
+Now whenever you share an image or gallery through Immich, it will automatically create the 
+correct public path for you.
