 One of the best javascript datagrid [SlickGrid](https://github.com/mleibman/SlickGrid) which was originally developed by @mleibman is now available to Angular. I have used a few datagrids and slickgrid beats most of them in terms of functionalities and performance (it can easily deal with even a million row).
 
 ### Angular Compatibility
-- version `1.x.x` for Angular 4 to 6 (*ng6, need `rxjs-compat` as shown in this [post](https://github.com/ghiscoding/Angular-Slickgrid/issues/36#issuecomment-395710915))
+- version `1.x.x` for Angular 4 to 6 
+   - Angular 6, is only supported through `rxjs-compat` as shown in this [post](https://github.com/ghiscoding/Angular-Slickgrid/issues/36#issuecomment-395710915). It's preferable to upgrade to Angular 7+ as soon as possible. 
 - version `2.x.x` for Angular 7+
 
 ### SlickGrid Source
-We will be using [6pac SlickGrid fork](https://github.com/6pac/SlickGrid/) (the most active fork since the original @mleibman fork was closed some time ago by his author personal reasons).

 ### Goal
 The goal is of course to be able to run SlickGrid within Angular 4+ but also to incorporate as much as possible the entire list of functionalities (and more) that SlickGrid offers (you can see a vast list of samples on the [6pac SlickGrid examples](https://github.com/6pac/SlickGrid/wiki/Examples) website).

 #### Material Theme
 Technically speaking, `Material` theme is not provided, but it should still work. 
-The styling might need some adjustments to make it look like `Material` but there's over 200+ [SASS variables](https://github.com/ghiscoding/Angular-Slickgrid/blob/master/dist/styles/sass/_variables.scss), 
-so I'm sure making a theme is doable and if you do, please, please contribute it as a new theme to the project. Thank you.
