+## Instructions
+
+Just download `dotnetfx35installer.exe` and run it. That's it.
+
+**You don't need the installation media. It's packaged in the executable!**
+
+## Rant
+
+It seems like quite a few people have an issue installing the Dotnet Framework 3.5.
+I was one of them. All the guides on how to fix this said to just download a new
+Windows ISO and grab the required installation files and use `DISM` to load it into
+Windows 10. Well, that's dumb. I'm not going to wait two hours just to take a
+couple of files out of the ISO. Spoiler: I did. So here are the files that you need
+to install Dotnet Framework 3.5. I'm not really sure about how legal this is to
+be redistributing these so don't hurt me, Microsoft. I'm really just trying to help
+out here. I'm not stealing anyone's data and I'm not making any money off of this
+redistribution.
+
+I hope this ends up helping someone.
