 ## Premise
 
-Each of these examples consists of a common part of code, shared by all examples, which contains all necessary boilerplate code and is not Brickworks-related, and a specific part which actually implements the audio engine. The common code is copied/generated by an external tool called [Tibia](https://github.com/sdangelo/tibia). If you downloaded an official Brickworks release you don't need to care about any of this - all needed files will already be present -, otherwise you first need to [run Tibia as outlined below](#tibia). You might also want to do that if you need to edit the location of third-party dependencies (this is better explained in the following platform-specific instructions).

+## Tibia
+
+### Prerequisites
+
+You need [Node.js](https://nodejs.org/en) and [npm](https://www.npmjs.com/) to be installed.
+
+### Usage
+
+Get [Tibia 0.1.0](https://git.orastron.com/orastron/tibia/releases/tag/v0.1.0), extract the `tibia` folder and place it in the same parent directory as the Brickworks folder. Then either `cd` to the `tibia` folder and `npm install dot`, or install the [dot npm package](https://www.npmjs.com/package/dot) globally and make sure that the `NODE_PATH` environment variable is corretly set to find it.
+
+Now you can `cd` to the `examples` folder and run `./tibia_gen.sh` to copy/generate files for all examples, or otherwise run `./tibia_gen.sh common` to only copy/generate files in `examples/common` or <code>./tibia\_gen.sh *example*</code> to do the same for files in <code>examples/*example*</code>.
+
+If you want to remove all files copied/generated by Tibia, and thus restore the `examples` directory as it would appear in the official repository, run `./tibia_clean.sh` from the `examples` directory.
