The github plugin itself should show up under Filters: Enhance.

If it isn't there, open the plugin in a text editor. Make sure the first line in the plugin text is

#!/usr/bin/env python

In Windows, Python files won't appear in a menu if this initialization string isn't the first line. Depending on how you copied from github, there may be other lines above the initialization line.

For most SCM and PY files, there is a registration section, usually at the end of the file. Part of the several-line entries will indicate where the installed plugin will appear in the main GIMP menus. in this case it is "<Image>/Filters/Enhance/Super-xBR(py)..." .

Yeah it doesn't work if you right-click and copy the .py to your plug-ins folder.
Open the file in GitHub page, so that you can copy/paste the code to your text editor (I'm using notepad++ on Windows) and save as SuperxBR.py. Then it will work.
Or download the attachment. Had to zip because you can't upload python files.

I just tried out this upscaler for the first time. It is dog slow and uses 3 passes. It also produces very poor quality upscale that is very pixelated. I wouldn't waste my time with this.

According to wikipedia xBR family of scaling algorithms are specifically meant for low-res pixel-art (emulators etc.), results with normal images may be therefore unsatisfactory. I only tested that it works.

Ok, that explains it. I don't do pixel art, so have no need for this.

It worked by copying and pasting into new .py text file.

It took one hour to run and results were comparable to gmic Anti aliasing.
Oh well, back to using Waifu2x I guess.

Thanks for the replies guys:)
