# Building (locally)

Note that github.io will automatically build this page, but you should probably
test it locally first.

## Prerequisits

Ubuntu

```console
$ sudo apt-get -y install ruby ruby-dev build-essential libz-dev
```

Fedora

```console
$ sudo dnf -y install ruby ruby-devel zlib-devel gcc g++ make redhat-rpm-config
```

Install bundler, which is used to install the dependencies specifically for
building this repo.

```console
$ gem install bundler
```

You may need to add the place gem's puts binaries to your `PATH`.

```console
$ export PATH="${HOME}/bin:${PATH}"
```

Make sure you're in the top level directory of this repo when you run the next
command.

```console
$ bundle install
```

## Build

```console
$ bundle exec jekyll serve --incremental
```
