Copyright

Applying the Apache 2.0 license to work

To apply the Apache 2.0 license to your work, two separate files need to be created in the root of the repository:

(1) a “NOTICE” file containing the following boilerplate notice:

Copyright <creation date> Intersect MBO

Licensed under the Apache License, Version 2.0 (the "License”). 
You may not use this file except in compliance with the License. 
You may obtain a copy of the License at http://www.apache.org/licenses/LICENSE-2.0.txt

either express or implied. See the License for the specific

(2) a “LICENSE” file containing the full license text which can be obtained from here.

Rationale

Apache 2.0 is a permissive license that is widely deployed and backed by a strong community. Apache 2.0 allows users the freedom to use the software for any purpose, to distribute it, to modify it, and to distribute modified versions of it under the terms of the license, without any concern about royalties.

A key advantage of the Apache 2.0 license is that it contains provisions that are absent from many other free and open source licenses (including the MIT license) and which provide more clarity to contributors and users alike.

However, for text we can typically be much less restrictive. For this a permissive license like Creative Commons is much more appropriate.
