+# postcss-icss-find-imports
+
+A PostCSS plugin for finding import statements in CSS that follows the ICSS specification, __but not removing them from the AST__, eg. for implementing dependency discovery.
+
+This code was adapted from [css-loader](https://github.com/webpack-contrib/css-loader) and modified to work as a stand-alone plugin.
+
+This documentation is rudimentary and will probably be improved at some point. Feel free to open an issue if something is unclear!

+
+## API
+
+Exports a plugin that is compatible with PostCSS 8.
+
+Takes no options upon initialization.
+
+When applied, it will find import statements in the code, exposing them as the following types of `messages` (from plugin `postcss-icss-parser`):
+
+- `import`: an import statement.
+	- `url`: The path/URL being imported from.
+
+The import statements __are not removed__ from the AST.
