Hibari 1.1 adds rudimentary Instapaper support. Right-clicking on links will offer an “Instapaper” menu item if you've entered your Instapaper username and password. There’s currently no UI for entering your Instapaper credentials—you need to use our defaults commands.
Open up Terminal, located in /Applications/Utilities/. Paste in the following two commands, substituting your credentials, and hit Return. Finally, restart Hibari.
defaults write com.violasong.Hibari instapaperUsername forrestgump
defaults write com.violasong.Hibari instapaperPassword fruitcompany
If you don’t have password, put in a blank one like this:
defaults write com.violasong.Hibari instapaperPassword ''
