Duplicate words

[samuel-williams-da]

I noticed a few places where we have "the the" in the docs.
I put together a quick regex to find duplicate words (\b([a-zA-Z]+)\s+\1\b) and in fact we have quite a few mistakes like this:

• the the
• in in
• want want
• to to
• and and
• of of

We might just want to find and replace these in the repo.
