 ## Data
 
-Ideally we could download the data on demand when building, but for now I'm copying `/var/lib/flatpak/appstream/eos-apps/x86_64/active/appstream.xml` and `/var/lib/flatpak/appstream/eos-apps/x86_64/active/icons/` from an Endless OS install to the root of this repo.

 ## Building
 
 This site is a simple Jekyll-powered site hosted by GitHub Pages. To run it locally, see [the GitHub docs](https://help.github.com/articles/setting-up-your-github-pages-site-locally-with-jekyll/).
 
-I recommend using `toolbox` to develop, especially if you're on Endless OS or Fedora Silverblue; see [this blog post](https://cassidyjames.com/blog/github-pages-jekyll-fedora-silverblue/) for details.
+I recommend using `toolbox` to develop, especially if you're on Endless OS or Fedora Silverblue; see [this blog post](https://cassidyjames.com/blog/github-pages-jekyll-fedora-silverblue/) for more details. But in brief, this should get you going:
+
+```shell
+toolbox enter
+sudo dnf install ruby ruby-devel openssl-devel @development-tools gcc-c++
+sudo gem install bundler
+bundle install
+```
+
+You may need to manually install some gems, e.g.:
+
+```shell
+sudo dnf install rubygem-nokogiri rubygem-crack
+```
+
+Then to run:
+
+```shell
+bundle exec jekyll serve --host 0.0.0.0
