-the one for Geany 1.22. If you send me an udpated and tested
-`geany-themes-0.2x.x.zip` or `geany-themes-0.2x.x.tar.bz2` file (or both),
-I will check them out and add them as updated download links here in the

+Installation
+------------
 
-Unix-like Installation
-----------------------
+**Note:** the following instructions will overwrite any themes with
+the same filename you have already installed, so if you have customized
+any of them, you will lose your customizations if you don't back them
+up first.
 
-Extract the tarball and copy all of the files in the `colorschemes` directory
-to your `~/.config/geany/colorschemes/` directory. Create that directory if it
-doesn't already exist.
+### Unix-like Systems
 
-Windows Installation
---------------------
+Extract the zip file, tarball or checkout with Git to a local 
+directory. In this directory you will find a sub-directory named 
+`colorschemes` which contains all of the color scheme files. Copy all of 
+these `*.conf` files into the directory named 
+`~/.config/geany/colorschemes/`, where `~` means your personal home 
+directory. Create the `~/.config/geany/colorschemes/` directory if it
+does not already exist.
 
-Extract the tarball and copy all of the files in the `colorschemes` directory
-to your `C:\Users\YourUserName\AppData\Roaming\geany\colorschemes` directory.
-Create this directory if it doesn't already exist.
+After copying the files you can choose a new theme by selecting
+`Change Color Scheme...` from Geany's `View` menu.
 
-**Note:** The Windows directory paths above are for Windows 7, they might be
-different for other Windows versions (see the Geany manual).
+### Windows
 
-**Note:** Both of the above instructions will want to over-write your existing
-colorschemes which you might have customized. Be sure to backup any files in
-those directories that you do not want over-written.
+Installing the themes on Windows is the same as with Unix-like systems 
+with the exception that the target directory will be different. With 
+Windows 7, the directory should be named
+`C:\Users\YourUserName\AppData\Roaming\geany\colorschemes`, but the 
+exact path may vary depending on your Windows configuration and/or 
+version. Refer to [the Geany Manual][man-paths] for more information on 
+configuration file paths.

+Documentation
+-------------
 
 If you want to add a theme, read the [ADDING-A-THEME.md][add-theme] file. If you
 are a package maintainer, consult the [MAKING-A-RELEASE.md][make-release] file. For
 all other cases, consult the official Geany documentation.
 
-Known Bugs
-----------
-
-## Backwards-compatiblity
-
-These color schemes are not compatible with older version of Geany, including
-its old filetypes files, which you may have customized and are found in
-your per-user configuration folder. All bets are off if you mix and match
-old filetypes/color schemes and the color schemes here. The best way to
-handle it is to simple move your old filetypes out of the way, copy the ones
-you want to customize from Geany's system data folder and hand-copy over the
-non-`[styling]` groups from the old filetypes file into the new one.
-
-## Ubuntu Unity
-
-There is a conflict in Geany's code when you are using Unity's DBUS menu (that
-global menu at the top of the screen). The fix for this is available in the
-1.22 release of Geany. To work around the problem in older versions, you can
-ensure that the environment variable `UBUNTU_MENUPROXY` is set to `0` before
-running Geany. This will disable Unity from stealing Geany's main menu and
-will leave it within Geany's main window. You should be able to edit your
-launchers for Geany to run like this `UBUNTU_MENUPROXY=0 geany`. You can even
-make a Bash alias if you wish.
+Other Themes
+------------
 
-Geany Themes was created and is maintained by Matthew Brush <matt@geany.org>.
+You can also also sometimes find bleeding edge themes which have yet to 
+be fully integrated into the repository by looking at the
+[Issues on Github][issues] labelled with the [`new-theme`][new-themes] label.
+There may also be some unofficial themes on [the wiki][wiki-themes].
+
+Be wary of old-style themes you may find in random places on the 
+Internet as they may only be compatible with old Geany versions before 
+1.22 and will likely result in grief. If the file doesn't contain a 
+section called `[theme_info]` it almost sure to be an incompatible 
+older theme. See below for more details.
+
+Compatibility
+-------------
+
+These color schemes are not compatible with older version of Geany 
+prior to 1.22, including its old filetypes files, which you may have 
+customized and are found in your per-user configuration folder. All 
+bets are off if you mix and match old filetypes/color schemes and the 
+color schemes here. The best way to handle it is to simple move your 
+old filetypes out of the way, copy the ones you want to customize from 
+Geany's system data folder and hand-copy over the non-`[styling]` 
+groups from the old filetypes file into the new one.
