Update README.md

updating README.md with more explicit initialization steps

Thanks for the improvements, added couple of comments, but looks good to me.

You don't need the -f environment.yml if the name of the file is environment.yml, since it's conda's default. Feel free to leave it if you prefer to be explicit.

[Aya-S]

I didn't know that was the default, good to know.

[datapythonista]

Small thing, but may be a colon at the end to show that you're talking about the next command (thought initially you were talking about the previous list of repos)

[datapythonista]

lgtm, thanks for the update

[WillAyd]

Shouldn't this be conda env create -f environment.yaml?

[datapythonista]

environment.yml is the default conda file name, so not needed.

[jorisvandenbossche]

Personally, even if it is the default, I find leaving it out just confusing (for all people that don't know or directly remember that this is the default)

[Aya-S]

ok, I see the non-explicit form is confusing to people. will change it back :D

[WillAyd]

Is this required for anything?

[Aya-S]

It introduces a newline. for better readability and clearer separation between the commands

Doesn't need to be part of this PR, but in running for the first time I found "make sure docker daemon is installed+running" would be useful
