+# Self-hosting Siftlode
+
+Run your own private Siftlode instance with Docker. You don't need the source code — the app runs
+from a prebuilt image, and everything user-facing (your admin account, Google sign-in, email) is
+configured in a web wizard on first start. There's no editing of config files by hand.
+
+## What you need
+
+- A machine with **Docker** and the **Docker Compose plugin** (Docker Desktop on Windows/macOS,
+  or Docker Engine on Linux).
+- A few hundred MB of disk and ~1 GB RAM free.
+- Optional: a domain name + reverse proxy if you want HTTPS / public access (see below).
+
+## 1. Get the files
+
+Download these into a new, empty folder:
+
+- `docker-compose.selfhost.yml`
+- `install.sh` (Linux/macOS) **or** `install.ps1` (Windows)
+
+The app image is published at `forge.b1fr0st.eu/peter/siftlode` (public — no login to pull).
+
+## 2. Run the installer
+
+**Linux / macOS:**
+
+```bash
+chmod +x install.sh
+./install.sh
+```
+
+**Windows (PowerShell):**
+
+```powershell
+./install.ps1
+```
+
+The installer asks for the **public URL** where the instance will be reached (just press Enter for
+`http://localhost:8080` to try it locally). It then:
+
+- generates the secrets it needs (`SECRET_KEY`, `TOKEN_ENCRYPTION_KEY`, a database password) into a
+  local `.env` file — keep that file private,
+- pulls the image and starts the app + database,
+- prints the **setup wizard URL**, which looks like `…/setup?token=…`.
+
+## 3. Finish in the web wizard
+
+Open the printed setup URL in your browser. The one-time token in it means only you (with access to
+the server logs) can run setup. Then click through:
+
+1. **Admin account** — your email + a password. This is how you'll sign in.
+2. **Google sign-in** *(optional)* — paste a Google OAuth client ID + secret to enable "Sign in with
+   Google" and pulling your YouTube subscriptions. Skip it to use email + password only.
+3. **Email / SMTP** *(optional)* — an SMTP server so the app can send verification and notification
+   emails. Skip it — without email, new registrations are simply approved by you (the admin) instead.
+4. **Finish** — the wizard disappears, the instance is now configured, and you land on the sign-in
+   page. Log in with the admin account you just created.
+
+That's it. You can change any of the optional settings later under the admin **Configuration** page.
+
+> The setup wizard only exists until you finish it. After that, the setup routes are disabled and
+> the token is invalidated — there's no setup surface left on a configured instance.
+
+## Getting a Google OAuth client (optional)
+
+Only needed for "Sign in with Google" / YouTube access. In the
+[Google Cloud Console](https://console.cloud.google.com/): create a project → **APIs & Services →
+Credentials → Create credentials → OAuth client ID** → *Web application*. Add your instance's
+`…/auth/callback` URL as an **Authorized redirect URI**, then copy the **client ID** and **secret**
+into the wizard's Google step. (Enable the **YouTube Data API v3** for the project too.)
+
+## HTTPS / public access
+
+The app is served on port `8080` over plain HTTP, which is fine for a LAN or a quick trial. For
+public access, put a reverse proxy (Caddy, Nginx, Traefik…) in front to terminate TLS, and set the
+**public URL** in the installer to your `https://…` address (this also marks the session cookie
+secure). If you've already run the installer, edit `OAUTH_REDIRECT_URL` in `.env` to the https
+callback URL and `docker compose -f docker-compose.selfhost.yml up -d`.
+
+## Day-to-day
+
+```bash
+# Update to the latest release
+docker compose -f docker-compose.selfhost.yml pull
+docker compose -f docker-compose.selfhost.yml up -d
+
+# Logs / status
+docker compose -f docker-compose.selfhost.yml logs -f api
+docker compose -f docker-compose.selfhost.yml ps
+
+# Stop
+docker compose -f docker-compose.selfhost.yml down
+```
+
+Your data (accounts, subscriptions, playlists, the video catalog) lives in the `siftlode_pgdata`
+Docker volume — back that up to keep your instance's state. Database migrations run automatically
+when the app starts, so updating is just pull + up.
