This command simplifies some of the steps. However, there's a gotcha: it
might fail if the database requires username and password and they
haven't been configured before executing it.
On our regular README, this link used to point to the documentation
site, which made sense because the documentation used to be on a
different repository. Now that the documentation is on this repository
as well, we can directly link to that file.
And, on the documentation README, we can also link to the local
installation instructions, just like we do in other places.
We include ImageMagick in the local installation instructions as well as
in the installer, but we forgot to add it to the list of prerequisites
in the README.
These files are essentially the same as our README files, only our
README files contain information that only makes sense in the context
of a repository.
This is the Ruby version CONSUL uses now. Thanks to that, we no longer
need to install an old version of libssl-dev for Ubuntu 18.04.
We could probably simplify the documentation using:
```bash
rbenv install `cat .ruby_version`
```
However, this would require downloading consul before installing Ruby,
which could be harder to document.
