The software is really easy to use, but here is a general rundown:

when you double click the .exe file which will be called "Schedule_Renders.exe" it opens a window which is the control panel as well as your file explorer where you will have to choose what .blend files you want to schedule for rendering. You can schedule as many as you want by simply setting up a time for one file then browsing for another.

When choosing what time you want it to render you have a few options:

year month day (you can optionally check a box that says "Today" which will block those out) if you do check the "Today" box then you will have the option to either set a specific time like 9:32am (Sorry I know some of you only use 24 hour clock).

Additionally you can also choose to set an actual timer so you can set a timer for 40 minutes instead of naming a specific time (I would recommend this method if you're going to schedule multiple projects).

This software does NOT work for MacOS.

This software is open source and free so please feel free to share it and spread the word I do not care what you do with it it's all yours.
