How to install:
Hit the download button
wait 'till it's done downloading (shouldn't take long)
double click the downloaded .crx file
note: if you want to use the theme in for example google chrome portable (not the default Google Chrome) then replace the last step by the following:
open a new tab in Google Chrome (where nothing can be dragged in like with for example onedrive, where if you drag a file from your computer to the site, it will upload it to onedrive). (chrome://newtab)
drag the .crx file from your downloads folder (or where ever you downloaded it to) in Google Chrome.

you get a warning message:
Trust me, it is safe, the crx comes from the internet, probably from someone (me) that you don't know. So trust me
seriously though, I didn't do anything malicious with the .crx file.
