+- `url` ___(required)___
+  - used to generate relative paths for the templates
+  - used to generate absolute paths for server-side meta tag rendering
+  - the api endpoint is used for rendering when the `fs` key is not present, and inside the whois widget
+- `server` _(optional)_
+  - used by the built-in static nodejs server
+  - otherwise use the nginx config below to serve the static content
+- `fs` _(optional)_
+  - used to load the dynamic data locally. Renders only when any of the files is modified in the last 10mins. Use the `--force` flag to force the render.
+  - otherwise falls back to making HTTP requests to the varnalab-api
+- `git` _(optional)_
+  - githook configuration for the varnalab-static repo
+  - used only in production
+
