Discussions is OUT!! 
For a long time ago, I've been looking forward to the discussions in GitHub. I believe that any documents about vim or SpaceVim is not enough for users to get what they want to know. 

The best way for vim users is to use a "system" like StackOverflow. However, StackOverflow is too serious for this small document-like project. Therefore, Discussions can play an important role in this project. 

Therefore, I recommend other users could also try to use Discussions in GitHub. 

I really want this project could help others learn how to use vim or SpaceVim efficiently and correctly, also, quickly as possible. 

PS: I hope this project could accumulate the knowledge provided in Discussions from time to time if Discussions is welcome by others as well.
