[docs] Why don’t you recommend to install using pip without cloning explicitly?

In this Get Started index document, it is unclear to me why you recommend to use an explicit git clone followed by a pip install -e . for end-users.

Why not recommending users to add the following line to their requirements.txt file:

teklia-dan @ git+ssh://git@gitlab.teklia.com/atr/dan.git

Which will be easily included in any project, without having to install dependencies manually.
