 ## Usage
 
-### Quick Start with npx
-
-Size Limit can be used with npx for quick size checks, but requires the appropriate plugin to be installed first due to its plugin architecture:
-
-1. Install the required plugin as a **dev dependency** (choose based on your needs):
-
-    ```sh
-    npm install --save-dev @size-limit/file  # For simple file size checks
-    # Or for other cases:
-    # npm install --save-dev @size-limit/webpack  # For webpack projects
-    # npm install --save-dev @size-limit/esbuild  # For faster checks
-    ```
-
-2. Run size-limit with **npx**:
-
-    ```sh
-    npx size-limit --limit "10 kB" dist/bundle.js
-    ```
-
-3. Run size-limit with **global** installation instead of npx:
-
-    ```sh
-    npm install --global @size-limit/cli
-    size-limit --limit "10 kB" dist/bundle.js
-    ```
-
-Note: This approach works best for quick checks. For long-term project maintenance and CI integration, we recommend the full installation methods described below.
