# License Information


<p>OGRE is released under an <a href="http://www.opensource.org/">open source</a> license, specifically the MIT License.

<p>Under  the <a href="../LICENSE">MIT License</a> you may use Ogre for any purpose you wish, without warranty, and modify it if you require, subject to one condition:</p>
<ol>
    <li>"The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software."</li>
</ol>

In practice this means that whenever you distribute your application, whether as binary or as source code, you must include somewhere in your distribution the text <a href="../LICENSE">in this file</a>. This might be in the printed documentation, as a file on delivered media, or even on the credits / acknowledgements of the runtime application itself; any of those would satisfy the requirement.

# Licenses for 3rd-party libraries used in OGRE

Several 3rd-party libraries are used in OGRE for various purposes, and the licensing details of each are given here.

## Core Dependencies

These are the libraries which the core of OGRE depends on, and are
therefore prerequisites for any use of OGRE. None of these libraries
have been modified from their original distributions, and they are all
licensed under liberal terms. You should read the detail of the
licenses when distributing an application since most require you to
include the license in your documentation. All the license texts are
included in the Docs/licenses folder.
