Environment variables that are to be added to the default query string are prefixed with `WSQS_` and then use the same key/value pairs generated by the [Permalink](#sharing-a-permalink-bookmarking) above, with the `- (dash)` character replaced by an `_ (underscore)`. For example, if you wanted to turn the travel forecast on, you would find `travel-checkbox=true` in the permalink, its matching environment variable becomes `WSQS_travel_checkbox=true`.
When using the Docker container, these environment variables are read on container start-up to generate the static redirect HTML.
## Music
The WeatherStar had wonderful background music from the smooth jazz and new age genres by artists of the time. Lists of the music that played are available by searching online, but it's all copyrighted music and would be difficult to provide as part of this repository.

## Customization
A hook is provided as `/server/scripts/custom.js` to allow customizations to your own fork of this project, without accidentally pushing your customizations back upstream to the git repository. A sample file is provided at `/server/scripts/custom.sample.js` and should be renamed to `custom.js` activate it.
When using Docker, mount your `custom.js` file to `/usr/share/nginx/html/scripts/custom.js` to customize the static build.
## Issue reporting and feature requests
Please do not report issues with api.weather.gov being down. It's a new service and not considered fully operational yet. I've also observed that the API can go down on a regional basis (based on NWS office locations). This means that you may have problems getting data for, say, Chicago right now, but Dallas and others are working just fine.
