+# What License Do You Need?
+
+## General License Overview
+
+Open-source projects are an important foundation for the software development ecosystem. Modern applications are depending more and more upon the work of enthusiast and experts. Open-source is not anymore just sharing knowledge and passion with everybody. Over last years, maintaining and developing those projects have became a highly responsible task.
+
+We identify the importance of the QuestPDF library in your projects, and therefore want to make sure you can safely and confidently continue the development. We strongly believe that a dual-licensing model is the best solution for all users: providing the best development experience and feature set for everybody and every project, but also offering stability for every professional and enterprise product.
+
+Being a healthy and growing community is our primary goal that motivates us to pursue professionalism.

+
+## What license do you need?
+
+Suppose you are consuming the QuestPDF library as a Direct Package Dependency for usage in a Closed Source software in the capacity of a for-profit company/individual with more than 1M USD annual gross revenue. In that case, you must purchase the QuestPDF Professional or Enterprise License, depending on the number of software developers.
+
+We love and highly appreciate the .NET Community. Therefore, most users are welcome to use the library entirely for free. If you do not meet the criteria described above, you are eligible to use the QuestPDF Community MIT License, without any limitations, even for commercial usage.
+
+If you still want to support library development, please consider purchasing the Professional License.
+
+Please find all details regarding the QuestPDF license on the [official webpage](https://www.questpdf.com/pricing.html).
+
+Being a healthy and growing community is the primary goal that motivates us to pursue professionalism. Thank you!
