 This extension allows you to **execute all lines inside `run()` up to the line where the cursor currently is** in the VS Code **Interactive Window**.
 
 ## Usage
-1. Place your cursor anywhere inside `run()`.
-2. Press **Cmd+Enter**.
-3. The extension will **automatically select and execute the code inside run() up to the cursor**.
+* If the cursor is anywhere outside the `run()` function, press `cmd+Enter` to execute the entire script in the interactive window. After doing this, the cursor will be moved to the beginning of the `run()` function.
+  * This is useful when you just opened a new data step script and haven't yet initialized an interactive window.
+* Once an interactive window has already been initialized, if the cursor is inside the `run()` function, press `cmd+Enter` to execute all the code inside the function until the current line (the current line will also be executed).
+  * This is useful while working on a data step, when you want to quickly test the entire content of `run()` from the beginning.
