How is software licensed to MIT? I am in the process of licensing my software and I don't know how or what to do to do it. I have seen how software can be licensed under the GPL.
The GNU GPL states that a notice like this should be placed at the beginning of every source code file:
Copyright (C)
This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.
This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
You should have received a copy of the GNU General Public License along with this program. If not, see http://www.gnu.org/licenses/
You just have to include this file along with the rest of your code:
https://opensource.org/licenses/MIT
You can specify at the beginning of each file that the license is MIT, but I don't consider it mandatory.
This is generic and applies to any software license.
