 This package contains common code shared between [`Giraffe.Htmx`](https://www.nuget.org/packages/Giraffe.Htmx) and [`Giraffe.ViewEngine.Htmx`](https://www.nuget.org/packages/Giraffe.ViewEngine.Htmx), and will be automatically installed when you install either one. It also contains htmx as a static web asset, allowing it to be loaded from your local (or published) project.
