 ## Fabric.js
 
+If you are still using Fabric.js v5 because you are maintaining a complex project you don't want to migrate, we made an effort to keep old documentation online.
+Please keep in mind the Fabric.js development team moved on to v6 and beyond and does not have time to keep updated 2 versions.
+All the resources of Fabric.js v5 are deployed [here](https://fabric5.fabricjs.com)] while (fabricjs.com)[https://fabricjs.com] focuses on v6 onward.

 Using Fabric.js, you can create and populate objects on canvas; objects like simple geometrical shapes — rectangles, circles, ellipses, polygons, or more complex shapes consisting of hundreds or thousands of simple paths. You can then scale, move, and rotate these objects with the mouse; modify their properties — color, transparency, z-index, etc. You can also manipulate these objects altogether — grouping them with a simple mouse selection.
