Hi - very new to coding (python) and algo trading. Is it possible for me to download and install LEAN locally?  Can I still access the data that I would have access to online or do I need to supply my own?  I have downloaded the zip file from GitHub but not sure where to go from there.

I'm basically looking for a way of being able to work on algos without internet connection + debug and test easily in something like Juypter.

Thanks, Andrew
