 ## Presentation
 
-> An interactive programming learning platform.  
+> Learn programming, one lesson at a time.
 
-This project aims to enable students to learn programming.
-
-It is also my capstone project for the [Web and Web Mobile Developer REAC certification](https://www.francecompetences.fr/recherche/rncp/37674/), which I am currently undergoing at [La Plateforme_](https://laplateforme.io).
+An accessible, Markdown-first platform for programming courses 
+where instructors write lessons in plain Markdown, 
+students follow them lesson by lesson in an interface built to RGAA standards.
 
+*Learn-dev* is a platform for publishing and following programming courses.   
+**Instructors** author lessons in plain Markdown, and the platform turns them into rich, safe pages: 
+tables, GitHub-style callouts, Mermaid diagrams, and code blocks, all sanitized server-side and rendered 
+in a light or dark theme. 
+**Students** enroll and progress lesson by lesson through an interface 
+designed to be accessible to everyone (RGAA/WCAG AA).
