Looks great to me! Sorry for the delay @ mahlzahn

Hi. thank you for this contribution. What is the licence for the PDF documentation. Do we have the right to distribute then here ?

The documentation of the new format was not uploaded by me (I just changed the name).

The documentation of the old format was uploaded by me. It is available from https://resources.3brain.com/f1/downloads/BrainWave_Documentation_for_BRWv.%203.x_and_BXRv.%202.x_FileFormats_v1.2.0.pdf (also on web.archive.org)

I don’t have distribution rights. If you prefer to remove them from here, we can do of course. I may contact 3Brain to ask for permission.

I got positive answer from 3Brain to share the documentation (@samuelgarcia, you should be in CC, too). Thus, I adjusted the README and also uploaded the new version of the documentation (the git commit message includes also the relevant parts of e-mail exchange).

Hi Robert . I receive the email to put also the documentation. Thanks a lot. I merge this.
