 ### Setup
 
 1. Install the package.

-      withHxPush "/some/new/url" >=> [other handlers]
+      withHxPushUrl "/some/new/url" >=> [other handlers]

+The `HxSwap` module has constants to use for the `HX-Reswap` header. These may be extended with settle, show, and other qualifiers; see the htmx documentation for the `hx-swap` attribute for more information.
+
 ### Learn
 
 The naming conventions of this library were selected to mirror those provided by htmx. The header properties become `Hx*` on the `ctx.Request.Headers` object, and the response handlers are `withHx*` based on the header being set. The only part that does not line up is `withHxTrigger*` and `withHxTriggerMany`; the former set work with a single string (to trigger a single event with no arguments), while the latter set supports both arguments and multiple events.

 This package enables [htmx](https://htmx.org) support within the [Giraffe](https://giraffe.wiki) view engine.

 ### Setup
 
 1. Install the package.
@@ -21,10 +23,14 @@ Support modules include:
 - `HxHeaders`
 - `HxParams`
 - `HxRequest`
-- `HxSwap`
+- `HxSwap` (requires `open Giraffe.Htmx`)
 - `HxTrigger`
 - `HxVals`
 
+There are two `XmlNode`s that will load the htmx script from unpkg; `Htmx.Script.minified` loads the minified version, and `Htmx.Script.unminified` loads the unminified version (useful for debugging).
+
+This also supports [fragment rendering](https://bitbadger.solutions/blog/2022/fragment-rendering-in-giraffe-view-engine.html), providing the flexibility to render an entire template, or only a portion of it (based on the element's `id` attribute).
+
 ### Learn
 
 htmx's attributes and these attribute functions map one-to-one. The lone exception is `_hxBoost`, which implies `true`; use `_hxNoBoost` to set it to `false`. The support modules contain named properties for known values (as illustrated with `HxTrigger.Load` above). A few of the modules are more than collections of names, though:
