The README.md may be updated to also list bleak into the list of dependencies.

And then if some specific versions of the requirements are needed (maybe all from latest git repositories), that should be mentionned too.

Is this related to: #21 ?

[koenvervloesem]

Yes, development has stalled because the code should be changed to follow the newest Textual release like in the PR you mentioned. There was also never an official release of Theengs Explorer because it was still in development. So for now there's no quick fix. If you really want to run Theengs Explorer now, your best bet is to start from PR #21.

OK thanks for the info. I'll give it a try.
