+
+[PostCSS Language Support] adds support for modern and experimental CSS within
+**Visual Studio Code**.
+
+<p align="center"><img src="https://raw.githubusercontent.com/csstools/postcss-language/master/preview/custom-rules.png" alt="" width="610"></p>
+
+This syntax is applied to `.css`, `.pcss` and `.postcss` files. It is also
+applied to `css` and `pcss` code blocks in Markdown, and also to `<style>` code
+blocks in HTML.
+
+## Installation
+
+1. Open the command palette and select **Extensions: Install Extensions**
+2. Search for **PostCSS Language Support**
+3. Click **Install**
+
+### Adding Support for Emmet
+
+1. Open the command palette and select **Preferences: Open Settings (JSON)**
+2. Add the following configuration:
+
+```json
+{
+  "emmet.includeLanguages": {
+    "postcss": "css"
+  },
+  "emmet.syntaxProfiles": {
+    "postcss": "css"
+  }
+}
+```
+
+## Differences from CSS Language Support
+
+**PostCSS Language Support** is derived from the native
+**CSS Language Support** built into **Visual Studio Code**, which is itself
+derived from the native **CSS Language Support** for **Atom**. This language
+support includes the following changes:
+
+### Modern CSS Features
+
+- Support is added for nesting rules, including the nesting selector (`&`), the
+  nesting at-rule (`@nest`), and `@media` and `@supports` at-rules.
+- Support is added for the `:blank` pseudo-class, as well as the `:is()` and
+  `:where` functional pseudo-classes.
+- Support is added for `prefers-color-scheme` and `prefers-reduced-motion`
+  within media queries.
+- Support is added for the `place-self` property.
+- Support is added for the `env()` function, as well as the `hwb()`, `lab()`,
+  and `lch()` color functions.
+- Support is added for the `emoji`, `fangsong`, and `system-ui` font families.
+- Support is added for the `border-block`, `border-inline`, `margin-block`,
+  `margin-inline`, `padding-block`, and `padding-inline` logical properties.
+- Support is added for `@custom-media` and `@custom-selector` at-rules.
+
+<p align="center"><img src="https://raw.githubusercontent.com/csstools/postcss-language/master/preview/nesting.png" alt="" width="278"></p>
+<p align="center"><img src="https://raw.githubusercontent.com/csstools/postcss-language/master/preview/variables.png" alt="" width="402"></p>
+
+### Syntactical Looseness
+
+- Support is added for nesting `@extend` and `@extends` at-rules.
+- Support is added for functional selectors (`%placeholder`).
+- Support is added for the CSS Modules `:global` rule, as well as the
+  `composes` declaration, and also `@value` declarations.
+- Support is added for sass `$variables`.
+- Support is added for single-line comments (`//`).
+- Support is added for `@custom-env` at-rules.
+- Support is added for unknown nesting at-rules, as well as unknown `@custom-`
+  prefixed at-rules.
