+We welcome contributions!
+
+Due to the fact that we intend to release Uplift on the Unity Asset Store, we will need to address copyright properly.
+
+We haven't yet decided if we go for a [Contributor License Agreement (CLA)](https://en.wikipedia.org/wiki/Contributor_License_Agreement) or a [Developer's Certificate of Origin (DCO)](https://developercertificate.org/).
+
+We will most probably decide this when we get our first external contribution, if any! So before you start, please take contact with us to discuss this.
+
+Thanks!
+
+The DragonBox team
