 Version 1.0 separates local generation for React and Next.js from the centralized legacy mode. The old config cannot be mixed with the new API in a single CLI invocation.
 
+## Installation
+
+Install the package as a development dependency so the migration uses the version recorded in the project lockfile:
+
+```bash
+npm install --save-dev @gromlab/svg-sprites
+```
+
 ## CLI
 
 The CLI now always requires an explicit `--mode` and a path to the configuration directory:
 
 ```text
-svg-sprites
-→ svg-sprites --mode <mode> <path>
+"sprites": "svg-sprites"
+→ "sprites": "svg-sprites --mode <mode> <path>"
 ```
 
 Choose a mode based on your environment:

 For regular React, use `defineReactSpriteConfig`. A folder and an explicit list of shared SVG files can be combined using `inputFolder` and `inputFiles`.
 
+Add the local CLI with the selected mode to `package.json`, for example:

+```json
+{
+  "scripts": {

+  }
+}
+```
+
+Run it with `npm run sprite:global` before importing the generated component.
+
 The old `publicPath` and `react` options are no longer needed. The generated module is created next to the config and adds its own `.gitignore`, while Vite, Webpack, or Next.js emits the SVG as a separate asset with a content hash.
 
 The `<SvgSprite icon="..." />` component is replaced by a component whose name is derived from `name`:
