+# Remark plugin npm2yarn
+
+## Motivation:
+
+Transforms npm bash command code blocks to Docusaurus tabs:
+
+The following (remove the `//`):
+
+````bash
+// ```bash npm2yarn
+// npm run build
+// ```
+````
+
+Becomes:
+
+![npm2yarn tabs example](./example.png)
+
+**Note**: it only works when used with Docusaurus themes that have the `Tabs` and `TabItems` components.
+
+## Install
+
+```bash
+npm install @docusaurus/remark-plugin-npm2yarn`
+```
+
+It is a Remark plugin, **not a Docusaurus plugin**, so you have to install it as a Remark plugin in the config of your Docusaurus plugins.
+
+```js
+module.exports = {
+  presets: [
+    [
+      '@docusaurus/preset-classic',
+      {
+        docs: {
+          // ...
