If you wish to forge-on with EndNote you’ll need to: 1) export your Mendeley library and import the references into EndNote, then 2) use EndNote to insert citations in the document (replacing the Mendeley citations).
1. To convert your Mendeley library to an EndNote library refer to the knowledgebase article http://endnote.com/kb/108063: “Transferring records from Mendeley Desktop”.
2. For a quick tutorial on EndNote X7’s features including inserting citations refer to the training video “How to use EndNote in 7 Minutes” at http://endnote.com/training ,
