 ## Usage
 
-Once installed you will have access to different executables:
-- `bundle-phobia`: to query package size.
-   Just invoke it with a list of package names and some options.
-- `bundle-phobia-install`: to conditionally install package if weight constraint are respected. This is a wrapper on `npm install`
+Once installed you will have access a single executable `bundle-phobia` (aliased to `bundle-phobia-cli` for `npx usage`), with two commands: 
+- `stats` to query package size. This is the default command, just invoke it with a list of package names and some options.
+   ```
+    $ bundle-phobia lodash react
+   ```
+- `install`: to conditionally install package if weight constraint are respected. This is a wrapper on `npm install`
+   ```
+    $ bundle-phobia install lodash react
+   ```
 
 Note that you can specify a version along with the package range such as an
 instance exact version `[email protected]` or range version `ora@^3.0.0`.
