## Building the documentation

The documentation HTML is produced with the Ruby-based `jekyll` tool.

1. Make sure Ruby 2.x is installed.
2. `gem install jekyll` if `jekyll` is not already installed.

> **Note**: If you are an ```Ubuntu user```, make sure ruby2.x-dev is installed.

## Viewing the documentation locally

To view the documentation on your system locally:

### Setup

1. `cd` into `docs/` directory
1. Copy the config file, `cp _config.yml _config.local.yml`
1. Edit `_config.local.yml` and change the `url:` value to `http://localhost:4000`. This local config file will be ignored by git.

### Run Jekyll

1. In a separate shell session, `cd` to the `docs/` directory, and do:
```
jekyll serve --incremental --config _config.local.yml
```

This will start an HTTP server at `http://localhost:4000/` that serves the docs built in the `_site` directory; and anytime the docs are rebuilt by you, it will serve the docs site on the fly. In your main shell session where you develop, if you change anything in `docs/` the jekyll server will rebuild those on the fly. But if you change anything about the Bulma SASS or CSS, you need to do `npm run start` to build the docs' CSS before you will see it in the browser. The process running `jekyll serve` will pick up the new CSS automatically.
