Hi Adrià,

Thanks for your reply. I wouldn't expect that, of course :-) In fact, I
think your instructions are generally very helpful for most distros,
albeit with people needing to substitute whatever package management
system for apt-get and all that. It was really just those one or two
minor points that made it confusing for me, and perhaps I can have a
look at doing a pull request as you say. Anyway, it's a great system and
I've already learned quite a lot from installing it, which is why I
wanted to put up the blog post in case it helps others :-)

Best wishes,


Talat
