+In order to use Magic Set Editor, you need to have libraries for wxGTK version
+2.8. This can be acquired from the Ubuntu/Debian package libwxgtk2.8-0. If you
+are using another distribution, you can probably find the library in a package
+somewhere. You also need Hunspell, which is in Ubuntu/Debian libhunspell-1.2-0.
+
+Due to wxWidgets sucking, there is a fair chance that this will not work out of
+the box on non-Ubuntu systems. If this is the case, please download the source
+package and compile it yourself.
+
+To install Magic Set Editor, please extract this tarball if you haven't already,
+and then run the install script. If run as root, it will install MSE to
+/usr/local/share/magicseteditor, if not, to ~/.magicseteditor. Fonts will be
+installed to /usr/local/share/fonts or to ~/.fonts.
+
+MSE will also place a symlink in either /usr/local/bin or ~/bin. They can be
+removed without affecting the install, and removing the installation directory
+will completely purge the system of MSE, except that some users' configuration
+files will still remain in ~/.magicseteditor for each user.
+
+You can override the installation, font, or symlink targets with the environment
+variables MSE_INSTALL_DIR, MSE_FONTS_DIR, and MSE_EXEC_SYMLINK respectively.
