I am very very new to Botpress. So far I have figured out that there is a web based SDK which I think is referred to cloud studio. There seem to be plenty of videos on youtube. But I also read that there is an offline SDK (not sure what its name is). Is there some documentation and a download link to that offline SDK? What I actually would like to do is to write a bot based on existing libraries, train it myself, and use it first of all offline just to learn some basics. Hope someone can shed some light.

Welcome, its nice to have you here 🙂 You are absolutely right, there is a version in the cloud (Cloud studio) and a version that you can host yourself (V12). I would advise you to try and ask in #1112845893931110402 . The people there knows much more about it than us 🙂
