+Customisations
+**************
+
+There are a few ways you can customise novelWriter youself. Currently, you can add new GUI themes,
+your own syntax themes, and install additional dictionaries.
+
+
+.. _a_custom_dict:
+
+Spell Check Dictionaries
+========================
+
+novelWriter uses `Enchant <https://abiword.github.io/enchant/>`_ as the spell checking tool.
+Depending on you operating system, it may or may not load installed spell check dictionaries.
+
+Linux
+   On Linux, you generally only have to install hunspell or aspell dictionaries on your system like
+   you do for other applications. See your distro's documentation for how to do this.
+
+Windows
+   For Windows, English is included with the installation. For other languages you have to download
+   and add dictionaries yourself. You can find the various dictionaries on the
+   `Free Desktop <https://cgit.freedesktop.org/libreoffice/dictionaries/tree/>`_ website. You should
+   find a folder for your language, if it is available at all, and download the files ending with
+   ``.aff`` and ``.dic``. These files must then be copied to the following location:
+
+   ``C:\Users\<USER>\AppData\Local\enchant\hunspell``
+
+   This assumes your user profile is stored at ``C:\Users\<USER>``. The last one or two folders may
+   not exist, so you may need to create them.
+
+
+.. _a_custom_theme:
+
+Syntax and GUI Themes
+=====================
+
+Adding your own GUI and syntax themes is relatively easy. The themes are defined by simple plain
+text config files with meta data and colour settings.
+
+In order to make your own versions, first copy one of the existing files to your local computer and
+modify it as you like.
+
+* The existing syntax themes are stored in
+  `novelwriter/assets/syntax <https://github.com/vkbo/novelWriter/tree/main/novelwriter/assets/syntax>`_.
+* The existing GUI themes are stored in
+  `novelwriter/assets/themes <https://github.com/vkbo/novelWriter/tree/main/novelwriter/assets/themes>`_.
+
+Remember to also change the name of your theme by modifying the ``name`` setting at the top of the
+file.
+
+For novelWriter to locate the custom theme files, you must copy them to the :ref:`a_locations_data`
+location in your home or user area. There should be a folder there named ``syntax`` for syntax
+themes and just ``themes`` for GUI themes.
+
+Once the files are copied there, they should show up in :guilabel:`Preferences` with the label you
+set as ``name`` inside the file.
+
+Theme CSS Files
+---------------
+
+If you wish, you can also modify the CSS styles of the GUI in addition to change colour settings.
+This is only available for GUI themes, and you do this by creating a file with the exact same file
+name as the ``.conf`` file with colour settings and give it the ``.qss`` extension.
+
+On Windows, file extensions may not be visible by default, so make sure you only have one file
+extension, and don't end up with two.
+
+The QSS files are Qt Style Sheet files. See Qt's
+`The Style Sheet Syntax <https://doc.qt.io/qt-5/stylesheet-syntax.html>`_` documentation for more
+details.

 If you are using Windows or a Debian-based Linux distribtuion, you can install novelWriter from
 package installers. If you are on macOS, you have the option to run novelWriter from a standalone
 folder. See :ref:`a_started_minimal`. This option is also available for Windows and Linux. The
 third option is to install novelWriter from the Python Package Index. See :ref:`a_started_pip`.
 
+Spell checking in novelWriter is provided by a third party library called Enchant_. Generally, it
+should pull dictionaries from your operating system automatically. However, on Windows they must be
+installed manually. See :ref:`a_custom_dict` for more details.

+novelWriter will create a few files on your system outside of the application folder itself. These

+
+
+.. _a_locations_conf:
+
+Configuration
+=============
+
+The general configuration of novelWriter, including everything that is in :guilabel:`Preferences`,
+is saved in one central configuration file. The location of this file depends on your operating
+system. The system paths are provided by the Qt QStandardPaths_ class and its ConfigLocation value.
+
+The standard paths are:
+
+* Linux: ``~/.config/novelwriter/novelwriter.conf``
+* macOS: ``~/Library/Preferences/novelwriter/novelwriter.conf``
+* Windows: ``C:\Users\<USER>\AppData\Local\novelwriter\novelwriter.conf``
+   
+Here, ``~`` corresponds to the user's home directory on Linux and macOS, and ``<USER>`` is the
+user's username on Windows.
+
+.. note::
+   These are the standard operating system defined locations. If your system has been set up in a
+   different way, these locations may also be different.

+.. _a_locations_data:
+
+Application Data
+================
+
+novelWriter also stores a bit of data that is generated by the user's actions. This includes the
+list of recent projects form the :guilabel:`Open Project` dialog. Custom themes are also saved
+here. The system paths are provided by the Qt QStandardPaths_ class and its AppDataLocation value
+on Qt 5.4 or greater, or DataLocation for earlier versions.
+
+The standard paths are:
+
+* Linux: ``~/.local/share/novelwriter/``
+* macOS: ``~/Library/Application Support/novelwriter/``
+* Windows: ``C:\Users\<USER>\AppData\Roaming\novelwriter\``
+   
+Here, ``~`` corresponds to the user's home directory on Linux and macOS, and ``<USER>`` is the
+user's username on Windows.
