(1) just using pygaggle, in which case pip is sufficient, and (2) developing/evaluating, in which we need to clone the entire repo

@rodrigonogueira4 @lintool do you guys think this helps distinguish between the two?

I think the installation instructions should be kept the same as before, i.e., pip install pygaggle, install torch, Download the index, etc...
Then, inside the section "## Running rerankers on CovidQA", we add the following instruction: "Before running these evaluations, you need to clone this repo git clone ...".

Ah okay, I guess those are needed even if you don't intend to run the evaluations. Sorry I have no clue about this...Will change
