You're absolutely right, and as a result the guide section of Parabot has a ton of well written guides for everyone to use!
That said, in the case that I'm mistaken and there is not one - or that it's out of date, I'll do my best to explain it here!
Creating a batch file is as easy as -
1. Right click your desktop, and hover over the, "New..." function popout. On that pop-out, you should see "Text Document." Clicking this will open a new, blank text document. This will be our work space.
2. In this blank text document, you have the ability to list specific parameters that the client will follow when the text document is saved as a, "batch file."
3. For the purpose of this short tutorial - as the poster above recommended testing, we will input, "java -jar parabot.jar -dev" into the document.
4. We will then click File>Save As> and provide the File Name: "run.bat" and change the Save as type: "All Files"
5.On your desktop, you should now see a white box, with a translucent cog in the middle - otherwise known as a batch file.
6. After that, you will download the Parabot client from the main website. After that, you will need to navigate to Documents, on your computer to where the Parabot client is saved. You will rename the client to, "parabot".
7. Finally, you will drag your newly created, "run," batch file into the, "Parabot," folder in Documents. ****NOTE - Do not try to put the batch file inside of the parabot client file, it simply needs to be in the Parabot FOLDER.
8. Now that you've successfully moved your "run," file into your Parabot folder, you should be able to double click the, "run," file.
***additional information - If you'd like to access this run file from the desktop, simply right click your run file in Documents, and create a shortcut that you can place on the desktop. BOTH the, "run," file and, "parabot," client must be present in Documents.
