+# Griffel processor for wyw-in-js
+
+A processor for [wyw-in-js](https://github.com/Anber/wyw-in-js) for that performs build time transforms for `makeStyles` & `makeResetStyles` [`@griffel/react`](../react).

+
+<!-- END doctoc generated TOC please keep comment here to allow auto update -->
+
+## Install
+
+```bash
+yarn add --dev @griffel/tag-processor
+# or
+npm install --save-dev @griffel/tag-processor
+```
+
+## How to use it?
+
+This package cannot be used solely, it should be paired with `@griffel/babel-preset` or `@griffel/webpack-loader`
+
+- For library developers, please use [`@griffel/babel-preset`](../babel-preset)
+- For application developers, please use [`@griffel/webpack-loader`](../webpack-loader)
+
+### Handling Griffel re-exports
+
+```js
+import { makeStyles, makeResetStyles } from 'custom-package';
+```
+
+By default, the processor handles imports from `@griffel/react` & `@fluentui/react-components`, to handle imports from custom packages settings you need to include meta information to a matching `package.json`:
+
+```json
+{
+  "name": "custom-package",
+  "version": "1.0.0",
+  "wyw-in-js": {
+    "tags": {
+      "makeStyles": "@griffel/tag-processor/make-styles",
+      "makeResetStyles": "@griffel/tag-processor/make-reset-styles"
+    }
+  }
+}
+```
+
+> **Note**: "custom-package" should re-export following functions from `@griffel/react`:
+>
+> - `__styles`
+> - `__css`
+> - `__resetStyles`
+> - `__resetCSS`
