+Web Monkey Scripts
+==================
+A collection of user scripts for different browsers. Mainly tested in chrome.
+
+Easiest way to import them is to use their raw URL's from this repo.
+For example; `reddit-hide-sidebar` has its main/index file @
+<https://git.lysator.liu.se/hugo/web-monkey-scripts/blob/master/reddit-hide-sidebar/index.js>
+
+Simply replacing blob => raw gives the actual text file, fit for a direct
+import.
