To speak to its English contents, not the translations it hosts, as most are speaking of --
'Thelema' is a decent section, but sometimes the versions on https://hermetic.com/ are better (footnotes linked, proper unicode symbols), and https://lib.oto-usa.org/libri/ are probably the most up-to-date (i.e. the fill->kill correction to be accurate to the Stele in AL[1]).
The Theosophy, Grimoires, and Wicca sections are very worthwhile. Where else are you going to get AE Waite's Goetia (etc.)[1] right next to Mathers/Aleister Crowley's Goetia [2]?
Edit to add: scans of original editions of Crowley's works are @ https://keepsilence.org/the-equinox/ , too
