This is a browser extension that lets you shorten long urls.
I had to make a change to the manifest.json since the browser was being so damn picky about it.
First you need to get the extension's files into a folder on your pc
Either run git clone https://github.com/tech128/Akari.git
or click the code button and download the zip and extract it somewhere
Now all you need to do to install it is load the unpacked extension in the browser extensions page
edge://extensions
chrome://extensions
Paste either of those into a new window or tab depending upon if you're running edge or chrome
Turn on developer options, then click load unpacked extension
Navigate to where you placed the files for the extension and select folder
That should be it, the extension should be loaded
You might have to click on the extension button at the top right and click a visibility button to make it visible on the toolbar
