+## Generating Test Files
+
+If there is a test file that needs to be added, a plain text `.txt` generally needs to be created as well. 
+
+**To run this script:**
+
+1. Run `Set-ExecutionPolicy RemoteSigned` OR `Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass` in Powershell (PS) Admin 7.0
+2. Have the PS script in the root of the repo
+3. Run `.\generate_txt.ps1 .\test_files\EXT_TYPE\FOLDER` (ex. `.\generate_txt.ps1 .\test_files\docx\apachepoi`) 
+
+*_Note: When generating more `.txt` files after the initial execution, Word should NOT be opening._
+
+**If Word is opening, follow these steps:**
+
+1. Uncomment [L27-29](https://github.com/SheetJS/js-word/blob/master/generate_txt.ps1#L27-L29) in the script 
+2. Comment [L26](https://github.com/SheetJS/js-word/blob/master/generate_txt.ps1#L26) in the script
+3. Rerun the script
+4. Undo Step 1 and 2
+
+_There should be `.skip` files for the password protected documents, and Word shouldn't open twice._
+
+**Outputs that are expected from this script, are the following:**
+
+- Word should be opening and closing (to grab and save the contents as .txt)
+- There should be .txt files being generated in the same folder that you ran the script
+
+**Edge cases to consider**:
+
+- The script will fail for documents that are broken (Word will prompt a notification to handle this)
