I finally found a little bit of time to prepare a draft. You can see the result on a development website:
As suggested by @MaximeJ, I splitted the “Developers” menu. To provide a better access to the online documentation, I splitted too the “Technical documentation” page in three pages:
- API documentation (Javadoc), providing links to the documentation of all official releases.
- Technical documentation (static web site generated by Maven), providing links to the documentation of all official releases.
- Tutorials, providing a summary of all available tutorials.
Suggestions and feedback are welcome!
When we agree, I will do the same for Rugged.
