-### htmx
-
-Idiomorph was created to integrate with [htmx](https://htmx.org) and can be used as a swapping mechanism by including
-the `dist/idiomorph-ext.js` file in your HTML:
-
-```html
-<script src="https://unpkg.com/idiomorph/dist/idiomorph-ext.min.js"></script>
-<div hx-ext="morph">
-
-    <button hx-get="/example" hx-swap="morph:innerHTML">
-        Morph My Inner HTML
-    </button>
-
-    <button hx-get="/example" hx-swap="morph:outerHTML">
-        Morph My Outer HTML
-    </button>
-
-    <button hx-get="/example" hx-swap="morph">
-        Morph My Outer HTML
-    </button>
-
-</div>
-```
-
-or by importing the "idiomorph/htmx" module:
-
-```html
-import "idiomorph/htmx";
-```
-
-Note that this file includes both Idiomorph and the htmx extension.
-
-#### Configuring Morphing Behavior in htmx
-
-The Idiomorph extension for htmx supports three different syntaxes for specifying behavior:
-
-* `hx-swap='morph'` - This will perform a morph on the outerHTML of the target
-* `hx-swap='morph:outerHTML'` - This will perform a morph on the outerHTML of the target (explicit)
-* `hx-swap='morph:innerHTML'` - This will perform a morph on the innerHTML of the target (i.e. the children)
-* `hx-swap='morph:<expr>'` - In this form, `<expr>` can be any valid JavaScript expression.  The results of the expression
-   will be passed into the `Idiomorph.morph()` method as the configuration.
-
-The last form gives you access to all the configuration options of Idiomorph.  So, for example, if you wanted to ignore
-the input value in a given morph, you could use the following swap specification:
-
-```html
-  <button hx-get="/example" 
-          hx-swap="morph:{ignoreActiveValue:true}"
-          hx-target="closest form">
-      Morph The Closest Form But Ignore The Active Input Value
-  </button>
-```
-
 ## Performance
 
 Idiomorph is not designed to be as fast as either morphdom or nanomorph.  Rather, its goals are:
