 # shadcn-ui
 
+A CLI for adding components to your project.
+
 ## Usage
 
+Use the `init` command to initialize dependencies for a new project.
+

+
+```bash
+npx shadcn-ui init
 ```
+
+## add
+
+Use the `add` command to add components to your project.
+
+The `add` command adds a component to your project and installs all required dependencies.
+
+```bash
+npx shadcn-ui add [component]
+```
+
+### Example
+
+```bash
+npx shadcn-ui add alert-dialog
+```
+
+You can also run the command without any arguments to view a list of all available components:
+
+```bash
 npx shadcn-ui add
