general: Reformat documentation with better formatting and wording 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://'). 4 years ago			`# Helper`

[Fix #120] Add documentation for trap 13 years ago
general: Update documentation better qualifying runcom paths 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. 4 years ago			`_The authors of this module should be contacted via the [issue tracker][1]._`
