# Contributor Licence Agreement (CLA)

We ask every contributor to sign a lightweight Contributor Licence
Agreement before we can merge a pull request.  The CLA does **not**
transfer copyright — you keep full ownership of your work.  It simply
grants the TrustGraph project a perpetual, royalty-free licence to
distribute your contribution under the project's
[Apache 2.0 licence](https://www.apache.org/licenses/LICENSE-2.0), and
confirms that you have the right to make the contribution.  This
protects both the project and its users by ensuring every contribution
has a clear legal footing.

When you open your first pull request, the
[CLA Assistant](https://cla-assistant.io/trustgraph-ai/trustgraph) bot
will post a comment asking you to review and sign the agreement —
it only takes a moment and you only need to do it once.
