Update README, use Markdown.

Remove unnecessary files with obsolete links.

Remove instructions from HACKING, as they contained old versions of
dependencies. It is now only a coding style guide.

+GDM - GNOME Display Manager
+===========================
+http://wiki.gnome.org/Projects/GDM/
+
+The GNOME Display Manager is a system service that is responsible for
+providing graphical log-ins and managing local and remote displays.
+
+## Building and installing
+To build and install GDM from source, just execute the following commands:
+
+```
+$ ./autogen.sh
+$ ./configure
+$ make
+$ sudo make install
+```
+
+## Contributing
+You can browse the code, issues and more at GDM's [GitLab repository].
+
+If you find a bug in GDM, please file an issue on the [issue tracker]. Please
+try to add reproducible steps and the relevant version of GDM.
+
+If you want to contribute functionality or bug fixes, please open a Merge
+Request (MR). For more info on how to do this, see GitLab's [help pages on
+MR's]. Please also follow the GDM coding style, which is documented in
+`HACKING`.
+
+If GDM is not translated in your language or you believe that the
+current translation has errors, you can join one of the various translation
+teams in GNOME. Translators do not commit directly to Git, but are advised to
+use our separate translation infrastructure instead. More info can be found at
+the [translation project wiki page].
