+# Create block routines
+An easy way of working with blocks in project base is to create the block through the package.json commands.
+
+## Create a new block
+To create a new block, run the following command in the terminal:
+
+```bash
+npm run create-block
+```
+
+This will prompt you for the block name, and then create the block as a new plugin in the `plugins` directory.
+
+## Create a innerblock block
+To create a new innerblock block, run the following command in the terminal:
+
+```bash
+npm run create-innerblock-block
+```
+
+This will prompt you for the block name, and then create the block as a new plugin in the `plugins` directory.
