One of the simplest ways to get PDF's into your Mendeley account is to drag and drop them into the software. Open 'Mendeley Desktop' to half your screen, click once on the file you want to import from your desktop and drag it over your citation listings in Mendeley.
The software automatically extracts citation information such as author, title and journal. If Mendeley cannot auto-fill all those fields, it alerts you that the citation is incomplete. You should always double check the accuracy of the citation information Mendeley extracts from these files for you.
