+```bash
+npm install @csstools/postcss-content-alt-text --save-dev
+```
+
+[PostCSS Content Alt Text] generates fallback values for `content` with alt text following the [CSS Generated Content Module].
+
+```pcss
+.foo {
+	content: url(tree.jpg) / "A beautiful tree in a dark forest";
+}
+
+/* becomes */
+
+.foo {
+	content: url(tree.jpg)  "A beautiful tree in a dark forest";
+	content: url(tree.jpg) / "A beautiful tree in a dark forest";
+}
+```
+
+## Usage
+
+Add [PostCSS Content Alt Text] to your project:
+
+```bash
+npm install postcss @csstools/postcss-content-alt-text --save-dev
+```
+
+Use it as a [PostCSS] plugin:
+
+```js
+const postcss = require('postcss');
+const postcssContentAltText = require('@csstools/postcss-content-alt-text');
+
+postcss([
+	postcssContentAltText(/* pluginOptions */)
+]).process(YOUR_CSS /*, processOptions */);
+```
+
+[PostCSS Content Alt Text] runs in all Node environments, with special
+instructions for:
+
+- [Node](INSTALL.md#node)
+- [PostCSS CLI](INSTALL.md#postcss-cli)
+- [PostCSS Load Config](INSTALL.md#postcss-load-config)
+- [Webpack](INSTALL.md#webpack)
+- [Next.js](INSTALL.md#nextjs)
+- [Gulp](INSTALL.md#gulp)
+- [Grunt](INSTALL.md#grunt)
+
+## Options
+
+### preserve
+
+The `preserve` option determines whether the original notation
+is preserved. By default, it is preserved.
+
+```js
+postcssContentAltText({ preserve: false })
+```
+
+```pcss
+.foo {
+	content: url(tree.jpg) / "A beautiful tree in a dark forest";
+}
+
+/* becomes */
+
+.foo {
+	content: url(tree.jpg)  "A beautiful tree in a dark forest";
+}
+```
+
+### stripAltText
+
+The `stripAltText` option determines whether the alt text is removed from the value.  
+By default, it is not removed.  
+Instead it is added to the `content` value itself to ensure content is accessible.
+
+Only set this to `true` if you are sure the alt text is not needed.
+
+```js
+postcssContentAltText({ stripAltText: true })
+```
+
+```pcss
+.foo {
+	content: url(tree.jpg) / "A beautiful tree in a dark forest";
+}
+
+/* becomes */
+
+.foo {
+	content: url(tree.jpg) ;
+	content: url(tree.jpg) / "A beautiful tree in a dark forest";
+}
+```
