+- Provide end users with access to the source code under the same open-source license conditions as provided by Licensor.
+- Clearly state in all marketing and sales materials that the Software is provided under a commercial license from Licensor, and provide a link back to https://changedetection.io.
+- Ensure end users are aware of and agree to the terms of the commercial license prior to resale.
+- Do not sublicense or transfer the Software to third parties except as part of an authorized resale activity.
