LICENSE file
Usually all projects start as private repo’s. A private repository does not need a LICENSE.md
file, it is always concidered proprietary.
If you work on a public repository, by convention it will follow the MIT license, and it should include a copy of this file in your repository: https://github.com/linkorb/skeleton/blob/master/LICENSE
The composer.json
file should also refer to the MIT license using this snippet:
"license": "MIT"
