-This compiled version of SlickGrid has been obtained with the Google Closure
-Compiler, using the following command:
-
-java -jar compiler.jar --js=slick.core.js --js=slick.grid.js --js=slick.editors.js --js_output_file=slick.grid.min.js
-
-There are two other files required for the SlickGrid view to work properly:
-
- * jquery-ui-1.8.16.custom.min.js 
- * jquery.event.drag-2.0.min.js
-
-These are included in the Recline source, but have not been included in the
-built file to make easier to handle compatibility problems.

-Please check SlickGrid license in the included MIT-LICENSE.txt file.

-     Cell/row DOM manipulations are done directly bypassing jQuery's DOM manipulation methods.
-     This increases the speed dramatically, but can only be done safely because there are no event handlers
-     or data associated with any cell/row DOM nodes.  Cell editors must make sure they implement .destroy()
-     and do proper cleanup.

+# Welcome to SlickGrid
+
+Find documentation and examples in [the wiki](https://github.com/mleibman/SlickGrid/wiki).
+
+
+**UPDATE:  March 5th, 2014 - I have too many things going on in my life right now to really give SlickGrid support and development the time and attention it deserves.  I am not stopping it, but I will most likely be unresponsive for some time.  Sorry.**
+
+## SlickGrid is an advanced JavaScript grid/spreadsheet component
+
+Some highlights:
+
+* Adaptive virtual scrolling (handle hundreds of thousands of rows with extreme responsiveness)
+* Extremely fast rendering speed
+* Supports jQuery UI Themes
+* Background post-rendering for richer cells
+* Configurable & customizable
+* Full keyboard navigation
+* Column resize/reorder/show/hide
+* Column autosizing & force-fit
+* Pluggable cell formatters & editors
+* Support for editing and creating new rows.
+* Grouping, filtering, custom aggregators, and more!
+* Advanced detached & multi-field editors with undo/redo support.
+* “GlobalEditorLock” to manage concurrent edits in cases where multiple Views on a page can edit the same data.
+* Support for [millions of rows](http://stackoverflow.com/a/2569488/1269037)
