+## `@tailwindcss/postcss` plugin API
+
+### Changing where the plugin searches for source files
+
+You can use the `base` option (defaults to the current working directory) to change the directory in which the plugin searches for source files:
+
+```js
+import tailwindcss from "@tailwindcss/postcss"
+
+export default {
+ plugins: [
+  tailwindcss({
+    base: path.resolve(__dirname, "./path")
+  })
+ ]
+}
+```
+
+### Enabling or disabling Lightning CSS
+
+By default, this plugin detects whether or not the CSS is being built for production by checking the `NODE_ENV` environment variable. When building for production Lightning CSS will be enabled otherwise it is disabled.
+
+If you want to always enable or disable Lightning CSS the `optimize` option may be used:
+
+```js
+import tailwindcss from '@tailwindcss/postcss'
+
+export default {
+  plugins: [
+    tailwindcss({
+      // Enable or disable Lightning CSS
+      optimize: false,
+    }),
+  ],
+}
+```
+
+It's also possible to keep Lightning CSS enabled but disable minification:
+
+```js
+import tailwindcss from '@tailwindcss/postcss'
+
+export default {
+  plugins: [
+    tailwindcss({
+      optimize: { minify: false },
+    }),
+  ],
+}
+```
+
+### Enabling or disabling `url(…)` rewriting
+
+Our PostCSS plugin can rewrite `url(…)`s for you since it also handles `@import` (no `postcss-import` is needed). This feature is enabled by default.
+
+In some situations the bundler or framework you're using may provide this feature itself. In this case you can set `transformAssetUrls` to `false` to disable this feature:
+
+```js
+import tailwindcss from '@tailwindcss/postcss'
+
+export default {
+  plugins: [
+    tailwindcss({
+      // Disable `url(…)` rewriting
+      transformAssetUrls: false,
+
+      // Enable `url(…)` rewriting (the default)
+      transformAssetUrls: true,
+    }),
+  ],
+}
+```
+
+You may also pass options to `optimize` to enable Lighting CSS but prevent minification:
+
+```js
+import tailwindcss from '@tailwindcss/postcss'
+
+export default {
+  plugins: [
+    tailwindcss({
+      // Enables Lightning CSS but disables minification
+      optimize: { minify: false },
+    }),
+  ],
+}
+```
