 ### Setup
 
-1. Open `Rename and Move PT STMT.bat` in Notepad
-2. Set the `ROOT` variable to your actual folder path:
-   ```bat
-   set "ROOT=C:\Users\Melissa\Documents\Patients"
-   ```
-3. Save and double-click to run
+1. Place `Rename and Move PT STMT.bat` in the root patient folder
+2. Double-click to run — it automatically uses the folder it lives in as the root
+
+### Dry Run
+
+The script defaults to **dry run mode** — it will print every action it would take without touching any files. To run for real, open the file in Notepad and change:
+
+```bat
+set "DRYRUN=1"
+```
+to:
+```bat
+set "DRYRUN=0"
+```
+
+Dry run output looks like:
+```
