 # FAQ
 
+## Commercial Guidelines
+
+### Are you open to commercial partnerships and collaborations?
+
+We are working to commercialize Immich and we'd love for you to help us by making Immich better. FUTO is dedicated to developing sustainable models for developing open source software for our customers. We want our customers to be delighted by the products our engineers deliver, and we want our engineers to be paid when they succeed.
+
+If you wish to use Immich in a commercial product not owned by FUTO, we have the following requirements:
+
+- Plugin Integrations: Integrations for other platforms are typically approved, provided proper notification is given.
+
+- Reseller Partnerships: Must adhere to the guidelines outlined below regarding trademark usage, and proper representation.
+
+- Strategic Collaborations: We welcome discussions about mutually beneficial partnerships that enhance the value proposition for both organizations.
+
+### What are your guidelines for resellers and trademark usage?
+
+For organizations seeking to resell Immich, we have established the following guidelines to protect our brand integrity and ensure proper representation.
+
+- We request that resellers do not display our trademarks on their websites or marketing materials. If such usage is discovered, we will contact you to request removal.
+
+- Do not misrepresent your reseller site or services as being officially affiliated with or endorsed by Immich or our development team.
+
+- For small resellers who wish to contribute financially to Immich's development, we recommend directing your customers to purchase licenses directy from us rather than attempting to broker revenue-sharing arrangements. We ask that you refrain from misrepresenting reseller activities as directly supporting our development work.
+
+When in doubt or if you have an edge case scenario, we encourage you to contact us directly via email to discuss the use of our trademark. We can provide clear guidance on what is acceptable and what is not. You can reach out at: questions@immich.app
