VisualCrossing

Register on VisualCrossing. Under Account Details, you should be able to generate an API key. Once you have that, add it to config.toml:

In config.toml, choose to use the VisualCrossing provider by adding it under the [weather] section:

[weather]
... your location details from the location step ...
provider = "visualcrossing"

Then add a section for the VisualCrossing provider with your API key:

[weather.providers.visualcrossing]
api_key = "XXXXXXXXXXXXXXXXXXXXXX"
