+Tarski
+======
+
+[Tarski][tarski] is an elegant, flexible [WordPress][wp] theme developed by
+[Benedict Eastaugh][exl]. As a WordPress extension it is licensed under the
+GPL; please consult the COPYRIGHT file that should have been provided with this
+README for more details.
+
+
+Installing
+----------
+
+Tarski is installed like any other WordPress theme: upload the files to the
+`wp-content/themes` directory of your WordPress installation, and activate it
+from the Appearance page in your WordPress admin panel.
+
+
+Customising
+-----------
+
+Tarski provides its own options page, allowing for the easy customisation of a
+number of aspects of the theme. Just go to the Tarski options page in the
+Appearance section of your WordPress admin panel and adjust the settings.
+
+
+Extending
+---------
+
+Apart from the options which Tarski supports two basic extension mechanisms:
+plugins and child themes. Both of these are provided by WordPress, but Tarski
+improves upon them in several ways, firstly by providing a larger repertoire of
+API hooks which plugins can use, and secondly by allowing users to select
+alternate styles and header images from child themes as well as Tarski itself.
+
+
+### Child themes
+
+Tarski's extensive API and large library of utility functions, allied to the
+customisability provided by its options page, makes it an excellent base for
+building [WordPress child themes][td].
+
+
+### Writing plugins
+
+[Tarski's theme hooks API][hooks] is an extension of the basic WordPress hooks
+API, and allows for major modifications to be made to almost every aspect of
+the theme's functionality. [Writing Plugins for Tarski][plugins] explains the
+process of creating a plugin that modifies some aspect of Tarski, while the
+[Hooks Reference][ref] is a complete API reference. A library of
+[example plugins][examples] rounds out the documentation with example code.
+
+
+Contributing
+------------
+
+Tarski relies on contributions from the community. The main areas of activity
+are: reporting bugs; creating and updating translations; building child themes;
+writing plugins; and lastly, improving the theme itself.
+
+
+### Reporting bugs
+
+Bugs should be reported on the [Tarski issue tracker][issues]. If you're not
+sure whether the behaviour you're observing is caused by Tarski or WordPress,
+or whether it's intentional or not, please post on the [Tarski forum][forum].
+Security issues should be reported [directly to Benedict][contact].
+
+
+### Translations
+
+There are a large number of translations already available for Tarski, but new
+and updated localisation files are always welcome. Please see the
+[localisation page][i18n] for more details.
+
+
+### Core contributions
+
+If you want to contribute directly to the core Tarski code, please
+[fork the project on GitHub][gh], make your changes in a topic branch and send
+a pull request. Contributions are particularly welcome in the following areas:
+
+  * Improving the hooks documentation
+  * Auditing the code for potential security issues
+  * Suggesting API extensions and improvements
+
+Happy hacking!
