+# Licenses
+
+See [LICENSE]() for the real license.
+This is a simplified version.
+
+There are two licences that cover the various Amulet codebases.
+1) The Amulet Map Editor License
+2) The Amulet Library License
+
+The former applies to the code that makes up the user interface (this repository) and the bundled form of the program and the latter applies to a number of libraries that Amulet uses.
+
+This summary will only cover the former. See the libraries for the latter.
+
+## Motive
+We want everyone to be able to use and contribute to Amulet, however developing the program costs money.
+Pathway are currently sponsoring the project but we need to design the licence to leave open potential income sources.
+
+## License Summary
+- The program is free to use for non-commercial users.
+- The program is free to use for purely educational commercial purposes.
+- If your use case does not fit in the above you should chat to us about a commercial licence.
+- You are allowed to modify the code however you wish and submit changes to us if you like.
+- You are not allowed to redistribute our code unless explicitly licenced to allow otherwise.
+
+
+## Frequently Asked Questions
+
+### Am I allowed to use Amulet to edit my world?
+
+You can use Amulet for free as long as:
+- You are not making money using Amulet.
+- You are not making money from the content made using Amulet.
+
+### Can I make money using Amulet in an education setting?
+You are allowed to use Amulet for free and make money if your usage is purely educational.
+
+Examples of educational usage:
+- Monetising videos or other materials explaining how to use Amulet.
+- Earning an income from teaching how to use Amulet or using Amulet to help teach other subjects.
+
+Any content (eg. worlds or structures) created during that time must be used solely for educational purposes and may not be sold or used in any other commercial environment.
+
+### Can I make money using Amulet?
+
+Commercial usage includes getting paid to use Amulet and the manufacture of content (eg. worlds or structures) that is later monetised.
+
+If you are using Amulet in a commercial setting that does not fit into the educational exception then you should contact us about a commercial licence.
+
+### Can I redistribute or rehost your code?
+No. Unless the code is explicitly licensed to allow otherwise, you cannot redistribute or rehost any code from Amulet.
+
+This includes the code in both source and compiled forms.
+
+The only exception to this is forking the original repository on Github with the aim to modify or improve on the code.
+
+Some files (such as editor operations) are released under the MIT licence to allow redistribution. These files will have the MIT licence at the top of the file.
+
+### Can I modify any part of Amulet?
+You are allowed to modify Amulet however you like.
+
+If you want to make improvements we accept code submissions through pull requests.
+
+### Can I make and sell plugins for Amulet?
+Plugins are extensions to Amulet. 3D Editor Operations are an example of plugins for Amulet.
+
+Operations are programs that can be run from within Amulet Map Editor in the operations tab of the 3D editor.
+
+You are allowed to make, distribute and license your operations however you wish.
+
+You are also allowed to make money through the sale or licensing of your operations if you wish.
+
+Your operations can call Amulet code but may not directly include any Amulet code unless licenced to allow redistribution.
