##Technical Details

This is the starting point for Denver visualizations. It unifies the look and feel of the sites. All visualizations share the same stack, built on top of jekyll. ETL scripts update the data from Denver's open data portal. See the readme for each repo for additional details.

Languages: Javascript, HTML, CSS, Ruby (ETL scripts)

Installation, Usage

Download dependencies in the command line: bundle

Local Development

1. Jekyll compiles everything into a static site in the _site folder. In order to get the latest changes and start the server, use the following command: jekyll serve --watch
2. Navigate to localhost:4000 to preview the site. Most changes will update immediately. The exception is changes to _config.yml. The server will need to be restarted in that case.

Deployment

1. Compile the site: jekyll build
2. Deploy contents of /_site to server.
