+		>BSD 3-Clause Clear</a> is a highly permissive license which allows content licensed under
+		it to be used in any way, whether in source or binary form, and allows sublicensing under a
+		different license, with the only restrictions being the original copyright notice must be
+		kept in order to attribute the original creator of the licensed content, and the name of the
+		project and/or its contributors may not be used to endorse or promote products derived from
+		the original project.<br>
+		BSD 3-Clause Clear is a derivative of <a href="https://spdx.org/licenses/
+		BSD-3-Clause.html"
+		>BSD 3-Clause</a>, which adds an explicit statement clarifying that patent rights are not
+		granted by the license alone, and must be granted separately by the copyright and/or patent
+		holder(s). We prefer this license over the standard BSD 3-Clause license due to this
+		explicit statement which removes any possibility of debate and misunderstanding in regards
+		to patents applied to code using a BSD 3-Clause license.</p>
