+# FAQ
+
+## Integrations
+
+
+### Can you create an integration for service X?
+
+You can request new integrations to be added to our forum. There is a special section for that where
+other users can also upvote it so that we know which integrations are important and should be
+created next. [Feature Request](https://community.n8n.io/c/feature-requests/nodes)
+
+
+### An integration exists already but a feature is missing. Can you add it?
+
+Adding new functionality to an existing integration is normally not that complicated. So the chance is
+high that we can do that quite fast. Simply post your feature request in the forum and we will see
+what we can do. [Feature Request](https://community.n8n.io/c/feature-requests/nodes)
+
+
+### How can I create an integration myself?
+
+Information about that can be found in the [CONTRIBUTING guide](https://github.com/n8n-io/n8n/blob/master/CONTRIBUTING.md)
+
+
+## License
+
+
+### What license does n8n use?
+
+n8n is licensed under [Apache 2.0 with Commons Clause](https://github.com/n8n-io/n8n/blob/master/packages/cli/LICENSE.md)
+
+
+### Why does n8n has the Commons Clause attached to the license?
+
+I love Open Source and the idea that everybody can use and extend what I wrote for free. But as much
+as money can not buy you love, love can sadly literally not buy you anything. Especially does it not pay for rent, food, health insurance, and so on.
+And even though people can theoretically contribute to a project are the main drivers which push a project
+forward the most time very few and normally the creators or the company behind the project. So to make sure that
+the project improves and stays alive long term did the Commons Clause get attached. That makes sure that
+no other person/company can make money directly with n8n. Especially not in the way it is planned
+to finance further development. For 99.99% of the people it will not make any difference at all but at
+the same time does it protect the project.
+
+As n8n itself depends on and uses a lot of other Open Source projects it is only fair and in our interest
+to also help them. So it is planed to contribute a certain percentage of revenue/profit every month to these
+projects. How much exactly is not decided yet.
+
+Started already with the first very small monthly contributions via [Open Collective](https://opencollective.com/n8n). It is not much yet as revenue is zero and profit in minus but it is at least a start. I hope to be able to ramp that up substantially over time.
+
+
+### Is n8n really Open Source?
+
+No, according to the definition of the [Open Source Initiative (OSI)](https://opensource.org/osd)
+is n8n currently not Open Source. The reason is that [Commons Clause](https://commonsclause.com) which takes away some rights got attached to the Apache 2.0 license.
+The source code is however open and people and companies can use it totally free.
+What is however not allowed is to make money directly with n8n. So you can for example not charge
+other people to host or support n8n.
+
+The support part is mainly there because it was already in the license and I am not a lawyer. So to make it simpler do I hereby grant anybody the right to do consulting/support without prior permission as long as it is less than 30.000 USD per year.
+
+If you have bigger things planned simply write an email to [license@n8n.io](mailto:license@n8n.io).
+
+
+### Why do you call n8n Open Source if the Open Source Initiative (OSI) says it is not?
+
+Because it is the best description and people know what Open Source is. It explains the best and fastest
+what can be done with the license n8n uses.
+
+If you ask people what it means when a project is Open Source they will mention things like:
+
+ - The source code is open
+ - Everybody can use it for free
+ - It can be extended
+
+Those are the things people associate with Open Source and what they care about most. And all of the
+above can be done with n8n. So there is currently simply no better term to explain it fast and simple.
+
+It is however also very important to me to not mislead anybody. That is why I try to mention everywhere
+directly that the [Commons Clause](https://commonsclause.com) got applied. So that the 0.01% of the people
+who care about that difference know about it.
