Hi Javier,
We made an effort to move a lot of the information from the wiki to the website. It would help if you could point out exact pieces of information that you would like to see on the new website that are currently missing (your link points to a large page, a lot of the information from there is already on the new website) - is there a particular description/explanation/tutorial you would like to see in there? Just let us know and we'll be glad to move it soon - the documentation is meant for users and we love user feedback. Note that there are multiple places on the new website for most of the information:
Also note that we have been putting most of the tutorials next to the code using Sphinx documentation. This is to allow pull requests for the tutorials so they are easier to update.
