+# Silverpeas
+
+## Overview
+
+Enterprise collaboration platform: intranet, document sharing, and communication tools.
+
+## Project Details
+
+-   **Project Repository:** [silverpeas.org](https://www.silverpeas.org/)
+-   **Container Image:** [silverpeas](https://hub.docker.com/_/silverpeas)
+-   **Documentation:** [Docker Hub](https://hub.docker.com/_/silverpeas)
+-   **Reverse Proxy Port:** `8000`
+
+## Getting Started
+
+1. Start the container: `docker compose up -d`
+2. Open http://localhost:8000 in your browser
+3. Follow the initial setup wizard to configure the application
+
+## Environment Variable Notes
+
+    SILVERPEAS_DB_PASSWORD – shared between the app and postgres
+
+## Volume Notes
+
+    /opt/silverpeas/data – documents and application data
+    /opt/silverpeas/log – logs
+    /var/lib/postgresql/data – PostgreSQL data
+
+## Network Notes
+
+Requires proxy network
+
+## Docker Run
+
+```bash
+docker run -d \
+  --name silverpeas \
+  -p 8000:8000 \
+  -e DB_SERVERTYPE=POSTGRESQL -e DB_SERVER=dbhost \
+  -e DB_NAME=silverpeas -e DB_USER=silverpeas -e DB_PASSWORD=pass \
+  silverpeas:latest
+```
+
+## Additional Notes / Gotchas
+
+The app is served under the `/silverpeas` path (http://localhost:8000/silverpeas). Default admin is SilverAdmin/SilverAdmin — change it.
+First startup is slow (Wildfly + DB migration).
