+# Notifuse
+
+## Overview
+
+Newsletter, marketing campaign, and transactional email platform (open-source Mailchimp/Resend alternative).
+
+## Project Details
+
+-   **Project Repository:** [GitHub](https://github.com/Notifuse/notifuse)
+-   **Container Image:** [notifuse/notifuse](https://hub.docker.com/r/notifuse/notifuse)
+-   **Documentation:** [docs.notifuse.com](https://docs.notifuse.com/self-hosting/installation)
+-   **Reverse Proxy Port:** `8080`
+
+## Getting Started
+
+1. Start the container: `docker compose up -d`
+2. Open http://localhost:8080 in your browser
+3. Follow the initial setup wizard to configure the application
+
+## Environment Variable Notes
+
+    NOTIFUSE_SECRET_KEY – encrypts all workspace secrets; NEVER change after setup or all stored credentials are lost
+    NOTIFUSE_ROOT_EMAIL – initial admin account
+    NOTIFUSE_API_ENDPOINT – public URL of the instance
+
+## Volume Notes
+
+    /var/lib/postgresql/data – PostgreSQL data
+
+## Network Notes
+
+Requires proxy network
+
+## Docker Run
+
+```bash
+docker run -d \
+  --name notifuse \
+  -p 8080:8080 \
+  -e API_ENDPOINT=http://localhost:8080 \
+  -e ROOT_EMAIL=admin@example.com \
+  -e SECRET_KEY=changeme \
+  -e DB_HOST=dbhost -e DB_USER=notifuse -e DB_PASSWORD=pass -e DB_NAME=notifuse \
+  notifuse/notifuse:latest
+```
+
+## Additional Notes / Gotchas
+
+Notifuse creates a separate Postgres database per workspace, so the DB user needs CREATEDB privileges (the postgres superuser in this stack has it).
+Sending requires an email provider (SES, Mailgun, SendGrid, Postmark, or SMTP) configured in the setup wizard.
