1) Login to CRXDE Lite (http://localhost:4502/crx/de), create folder /apps/eaem-touchui-cfm-links-plugin

2) Create node /apps/eaem-touchui-cfm-links-plugin/clientlib of type cq:ClientLibraryFolder, add String property categories with value dam.cfm.authoring.editors, String[] property dependencies with value underscore, granite.shared

3) Create file (nt:file) /apps/eaem-touchui-cfm-links-plugin/clientlib/js.txt, add

                        cfm-rte-links-plugin.js

4) Create file (nt:file) /apps/eaem-touchui-cfm-links-plugin/clientlib/cfm-rte-links-plugin.js, add the following code

(function ($, $document) {
    var EAEM_LINK = "eaemLink",
