+# Portus
+
+## Overview
+
+Web UI and authorization service for on-premise Docker registries.
+
+## Project Details
+
+-   **Project Repository:** [GitHub](https://github.com/SUSE/Portus)
+-   **Container Image:** [opensuse/portus](https://hub.docker.com/r/opensuse/portus/)
+-   **Documentation:** [port.us.org](http://port.us.org/)
+-   **Reverse Proxy Port:** `3000`
+
+## Getting Started
+
+1. Start the container: `docker compose up -d`
+2. Open http://localhost:3000 in your browser
+3. Follow the initial setup wizard to configure the application
+
+## Environment Variable Notes
+
+    PORTUS_FQDN – hostname Portus is reached at (must match registry config)
+    PORTUS_SECRET_KEY_BASE – generate with `openssl rand -hex 64`
+    PORTUS_PASSWORD – internal password Portus uses to talk to the registry
+
+## Volume Notes
+
+    /var/lib/mysql – MariaDB data
+
+## Network Notes
+
+Requires proxy network
+
+## Docker Run
+
+```bash
+docker run -d \
+  --name portus \
+  -p 3000:3000 \
+  -e PORTUS_MACHINE_FQDN_VALUE=portus.localhost \
+  -e PORTUS_SECRET_KEY_BASE=changeme \
+  -e PORTUS_PASSWORD=changeme \
+  -e PORTUS_DB_HOST=dbhost \
+  opensuse/portus:2.5
+```
+
+## Additional Notes / Gotchas
+
+Portus was abandoned by openSUSE/SUSE years ago — kept here for reference only. It also needs a Docker registry container configured with Portus as its token auth endpoint (not included). For a maintained registry UI consider Harbor or the built-in gitea registry.
