 # Contributing
 
-If you are contributing to this project, and specifically adding code, you are reputed to have read and agreed with this file content.
+Thank you for your interest in contributing to Azimutt Inspector!
+We welcome contributions from the community and appreciate your help in making the project better.
 
-## License
+If you are contributing to this project and specifically adding code, you are reputed to have read and agreed with this file content.
 
-This project is in a very early phase, its **licencing model is not decided yet**.
+## What You Can Contribute To
 
-By contributing to it, you consent to give unlimited rights to the repository owners on your contributions.
-They may choose any license for any part of the code and can clean the history.
+Contributions to the OSS core are welcome and governed by the MIT License.
+By submitting a pull request to OSS code, you agree your contribution is licensed under MIT.
 
-## The future
+The enterprise directories (`ee/`, `backend/src/ee/`, `frontend/src/ee/`,`packages/core/src/ee/`) are **not open for external contributions**.
+Pull requests targeting these directories will be closed. This is necessary to maintain clear copyright ownership over commercially licensed code.
 
-Not making any engagement here, but the application could be released under an Open Source license, and some plugins and extensions could have a commercial license.
+If you have a feature idea for the enterprise edition, please open an issue to discuss it —
+we may implement it ourselves and credit you.
+
+## Contributor License

 Self-Driving Database platform that proactively avoids incidents and optimizes your databases.
 It's plug-and-play with built-in analysis, but you can also provide your own scripts using [plugins](docs/plugins.md).

-More details on [installing Azimutt Inspector](docs/install.md).
+After startup, collectors run immediately and analyzers follow. If you used `QUICKSTART_DB`, you'll see your first alerts and suggestions within a few seconds. If you configure database instances from the UI, collectors will run immediately, but analyzers will follow their schedule. For fast analysis you can manually trigger them from the database instance item.
+
+Azimutt Inspector only requires **read-only access** to system tables on your managed databases (see [install guide](docs/install.md)).
 
 If you don't have a database to monitor, use the [sample](./demo/sample/README.md) one in the [demo](./demo/README.md) folder with Docker Compose.
 
 
+## Security
+
+Azimutt Inspector is designed for **on-premise deployment**, your data never leaves your infrastructure.
+It connects to managed databases with **read-only access** using a connection pool with a single connection, and all stored secrets are encrypted at rest.
+
+More details in the [security documentation](docs/security.md).
+
+
+## Community vs Enterprise
+
+Azimutt Inspector Community edition is meant to bring huge value for personal use or small teams.
+Large organizations are encouraged to use the Enterprise Edition, it adds:
+
+- Multi-database monitoring and auto-discovery
+- User authentication (local, OAuth) and authorization (RBAC)
+- Advanced collectors, analyzers, and notifiers (logs, AI-powered...)
+- PostgreSQL storage
+- MCP server
+- Support
+- And more...
+
+More details in the [Enterprise Edition documentation](docs/ee.md).
+
+
+## License
+
+Azimutt Inspector is open-core software.
+
+The **core** is open source under the [MIT License](LICENSES/MIT.txt) —
+free to use, modify, and distribute without restriction.
+
+The **enterprise features** (in `ee/` directories) are licensed under the [Elastic License 2.0](LICENSES/ELv2.txt) —
+free to use internally, but you may not offer them as a managed service or circumvent license key mechanisms.
