Zsh and Prezto files don't always reside in `~/`. Instead, they have
a more spec compliant location (`${ZDOTDIR:-$HOME}/`). Make them
unambiguous in the documentation. Likewise, for `$GNUPGHOME`.
Further, add instruction for optionally setting up Prezto in
`$XDG_CONFIG_HOME`.
While at this, also add clarification on relative ordering of some of
the modules, apply more formatting tweaks and doc improvements.
General purpose reformating and rewording in (a few places). This should
also make markdown linting happier.
Prefer back-ticks wherever useful and use `console` for code blocks to
be executed on terminal.
Also, update references links wherever possible (including update from
'http://' to 'https://').
There are a number of things happening here.
- Extra support for yaourt has been removed
- Docs have been updated to explicitly call out that AUR helpers are not
officially supported
- aurutils has been suggested to make common operations easier
- A utility function called aurget (similar to aurfetch from aurutils)
has been added to make cloning AUR repos easier.
Fixes#1531
