Eli Schwartz 78774647e1 docs: fix seriously dangerous download instructions for Arch Linux
The current instructions tell users to perform two actions:
- update the package database
- install the jq package

The only thing users need to or should be doing is actually installing
the jq package -- regardless of which version is being installed.
Guidelines on how to perform system updates are massively out of scope.

In the case of partially performing a system update as a prerequisite
for installing jq, the official guidance from Arch Linux is not to do
this: partial updates are not supported, we refuse to support them, and
anyone who does try to perform them anyway is assumed to know so much
about their system that they clearly do not ever need help from anyone
else (which is a good thing since they won't get it). The result is a
frankensteined system that can only ever be supported by the person who
frankensteined it to begin with. The only reason the package manager
even allows it to occur in the first place is because other
distributions using pacman might have different LTS policies, and
because it would prevent expert users from being in control of their
system, as per the traditional Unix philosophy:

"Unix was not designed to stop you from doing stupid things, because
that would also stop you from doing clever things."

Consequences of performing partial updates without understanding the
ramifications in extensive detail can include breaking the partially
updated application (jq), breaking any application that shares a mutual
dependency with the partially updated application (which jq is *lucky*
to only depend on the ever-backwards-compatible glibc), or breaking the
entire operating system by leaving armed traps behind for the next time
a `pacman -S new-package` is executed and thereby breaks *its* cascading
dependencies.

Documentation

The jq website, manpages and some of the tests are generated from this directory. The manual is a YAML file in content/manual.

To build the documentation (including building the jq manpage), you'll need python3 and pipenv. You can install pipenv like so:

pip install pipenv

Though, you may need to say pip3 instead, depending on your system. Once you have pipenv installed, you can install the dependencies by running pipenv install from the docs directory.

Once this is done, rerun ./configure in the jq root directory and then the Makefile will be able to generate the jq manpage.

To build the website, run pipenv run ./build_website.py from inside the docs directory.
