+--- Creating a New Extension ---
+
+To create a new extension, add a subdirectory in extensions.
+Then create a Makefile.am like the one in example, replacing
+the EXTENSION_ID with the basename of your extension, which
+must match the UUID in metadata.json.
+If you need additional files, add them to EXTENSION_EXTRA.
+
+Then modify extensions/Makefile.am and configure.ac. It should
+be pretty self-explanatory.
+
+Don't forget to add any translatable file to po/POTFILES.in, and
+then you're done.
+The Gettext domain you should choose is gnome-shell-extensions,
+not gnome-shell, unless you're sure there is the string you
+need in gnome-shell.
+
+--- Coding Style ---
+
+Generally, we follow GJS coding style (you can find it at
+http://git.gnome.org/browse/gjs/tree/doc/Style_Guide.txt), which
+in short is: indent 4 spaces, no tabs, space after comma, no space
+after function call.
+
+The Emacs mode line for this
+/* -*- mode: js2; js2-basic-offset: 4; indent-tabs-mode: nil -*- */
+
+Imports should be at the top, in two groups, one for standard
+imports (like imports.lang or imports.dbus) and introspection,
+the other for Shell API. Within the same group, put everything
+in alphabetic order.

-## Creating a New Extension
-
-To create a new extension, add a subdirectory in extensions. Then create
-a meson.build from the provided [template](extensions/meson.build.template).
-If you need additional sources, add them to extension_sources. Similarily add
-GSettings schemas to extension_schemas and other files to extension_data.
-
-Then modify the [toplevel Meson file](meson.build) to add the new
-extension name in the appropriate set (that is one of classic_extensions,
-default_extensions or all_extensions).
-
-Don't forget to add any translatable file to po/POTFILES.in, and

-
- * places-menu
