-
-In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
-
-## Our Standards

-
-* Using welcoming and inclusive language
-* Being respectful of differing viewpoints and experiences

-2. contribute code and/or configuration to the repository (see [the development guidelines](https://mailu.io/contributors/guide.html) for details);
-3. contribute localization to your native language (see [the localization docs](https://mailu.io/contributors/localization.html) for details);

+Simple yet full-featured mail server as a set of Docker images.
+The idea behing Mailu is identical to motivations that led to poste.io:
+providing a simple and maintainable mail server that is painless to manage and
+does not require more resources than necessary.
+
+People from poste.io did an amazing job at accomplishing this ; any company
+looking for a serious yet simple mail server with professional support should
+turn to them.
+
+This project is meant for free software supporters and hackers to reach the
+same level of functionality and still be able to host a complete mail server
+at little cost while running only FOSS, applying the KISS principle and being
+able to fine-tune some details if needed.
