 A Cytoscape.js extension that wraps the [qTip jQuery library](http://qtip2.com)
 
+**It is recommended that, where possible, you use [`cytoscape-popper`](https://github.com/cytoscape/cytoscape.js-popper) with `tippy.js` instead of `cytoscape-qtip`.**
+
+- The [`qtip2`](https://github.com/qTip2/qTip2) library that this extension wraps is no longer maintained by its author.
+- `qtip2` does not have proper support for npm+webpack and npm+browserify, whereas `cytoscape-popper` does -- as do `popper.js` and `tippy.js`.
+- `cytoscape-popper` does not require `jquery`.
+- `qtip2` requires the use of `jquery@1` or `jquery@2`, which are both no longer maintained.
