+# Open Source projects using Catch2
+
+Catch2 is great for open source. It is licensed under the [Boost Software
+License (BSL)](../LICENSE.txt), has no further dependencies and supports
+two file distribution.
+
+As a result, Catch2 is used for testing in many different Open Source
+projects. This page lists at least some of them, even though it will
+obviously never be complete (and does not have the ambition to be
+complete). Note that the list below is intended to be in alphabetical
+order, to avoid implications of relative importance of the projects.
+
+_Please only add projects here if you are their maintainer, or have the
+maintainer's explicit consent._
