Closes #408

[trevorcampbell]

• some minor polish
• changed "our..." and "we..." to "your..." and "you..." (these are instructions)

@ttimbers I think the instructions for installing miniconda are probably fairly brittle. It's a specific set of vague commands like "press enter", "type yes", etc. So if miniconda ever changes the order/prompts during installation, these will break.

Perhaps it's just better to give broader advice here instead of specific actions? Like "follow the prompts and agree to blah, make sure you tell it to run conda init, etc"

aside from that you're good to merge!

Good point @trevorcampbell - will remove those and replace with a more general statement and then merge this.
