 - [Statiq Framework](https://github.com/statiqdev/Statiq.Framework) and most other peripheral Statiq projects such as the [web site](https://github.com/statiqdev/statiqdev.github.io) are provided under a permissive MIT open-source license. This scheme is commonly referred to as "[open-core](https://en.wikipedia.org/wiki/Open-core_model)" because the core of the project is available as open-source while expanded capabilities are offered under more restrictive terms.
 
+## How do I purchase a private license for one or more developers?
+
+Please purchase licenses from the Statiq website at [https://www.statiq.dev/support/](https://www.statiq.dev/support/).
+
+If you require an invoice, please [contact me](mailto:dave@daveaglick.com) and I can send you one that contains payment
+instructions and a link for direct payment. Please include your billing name (or company name), billing email address,
+billing postal address, how many licenses should be included on the invoice, and any other details.

+**Note that only commercial use requires a license**. If you are only using Statiq Framework or are using Statiq Web or other Statiq projects that are licensed under the public license but aren't exceeding the small business thresholds of employees and revenue, you don't need a private license. Other than the small business employee and revenue clause, the public license is essentially the same as any other permissive open-source license. Explicit exceptions are also provided in the public license for non-commercial and trial use to make that distinction clear.

 ## I still have concerns about the vagueness and lack of legalese in the license.
 
 The simplicity of the license is intentional.
