Add WSL guidance to start guide

Fixes #16

Hm, did you check out those files somewhere on your Windows hard drive (/mnt/c/... in WSL) or on WSL's disk?

[Ruzihm]

oh jeeze yes. should i go fix the line endings?

[AEFeinstein]

The bash thing was still useful, but the file permissions definitely felt odd. Windows and Linux still aren't quite best friends, but you can access your WSL drive from Windows explorer.exe at \\wsl$\Ubuntu

Oh, I see what you're getting at. I'll re-open then.

Basically, because I cloned into /mnt/c/..., crosstool-NG threw a fit about directory permissions. Should I remove that part and instead add a bit about not cloning into a windows directory e.g. /mnt/c/...?

[AEFeinstein]

That would be a wise bit in the guide, yes.

Actually, with cloning into a non-windows dir, the case insensitivity fix may not be necessary. Let me close this again and update with my findings.
