4.3 Third Party’s Content

Before up-loading any Third Party’s Content, you must make sure that you have the right to up-load them on CP2K Lab, which is an open environment.

4.5 Contributions Under Repository License

Whenever you make a contribution to any CP2K Lab application repository containing notice of a license, you license your contribution under the same terms, and you shall make sure that you have the right to license your contribution under those terms. If you have a separate agreement to license your contributions under different terms, such as a contributor license agreement, that agreement will supersede.

However, you waive these rights and agree not to assert them against Mr. Schütt, to enable Mr. Schütt to reasonably exercise the rights granted in Section 4, but not otherwise.
