+# Manage Local Documentation
+
+Documents from `Vutron` can be viewed in the local environment through the VitePress viewer.
+
+This function works only when the entire project is cloned. If you created the project with `npm init`, the `docs` folder is not included.
+
+Since VitePress and related plugin packages are configured to be selectively installed, they cannot be installed with `npm i`.
+
+Install the relevant packages using the following preconfigured script commands:
+
+```shell
+$ npm run docs:install
+```
+
+You can run the local server where the documents are hosted via the command below.
+
+```shell
+$ npm run docs:dev
+```
