I use the DataTables download page to add the packages I require for my project and then use the 'Download' tab at the bottom to receive the files to put in my project. I put the full DataTable folder that's been extracted into my project /libraries/ folder. Upon looking into the folder I received it does not include the licence agreement file for MIT which (unless my understanding is wrong) I need to include in my project as per the licence?
Maybe the line about keeping the copyright agreement on https://datatables.net/license/ is enough? I just thought you had to include the actual licence file directly in your project?
Also after looking at the licencing page I'm pretty sure it means I can use it in a commercial proejct (I want to sell something which uses datatables) but just wanted to treble check this is the case.
