## What Is Jekyll
For those unfamiliar with how Jekyll works, check out [jekyll.rb] for all the
details, or read up on the basics of [front matter], [writing posts] and
[creating pages].
[jekyll.rb]: https://jekyllrb.com/
[front matter]: https://jekyllrb.com/docs/frontmatter/
[writing posts]: https://jekyllrb.com/docs/posts/
[creating pages]: https://jekyllrb.com/docs/pages/
## Hack On It
The only prerequisite is [Docker](https://www.docker.com/). If you're on Debian, installing is easy.
```bash
$ curl -fsSL https://get.docker.com -o get-docker.sh # have a look if you want
$ sh get-docker.sh
```
Fire up the container with the following.
$ make dockerserver
Then visit the locally running website.
> http://localhost:4000
Then you can edit the files as normal and reload the page.
## Notes
1. For configuration, please note, we now use a `dev` environment config file: `_config_dev.yml`
