 the code in the project is formatted in the same way. The following rules

-- use tabs instead of spaces
+- use tabs instead of spaces (set your editor to show tabs as two spaces.) Only
+  exceptions are Makefiles, that need spaces in some places (for example the

 - trailing whitespaces must be eliminated

+Developing Packages
+-------------------
+
+If you want to develop your own external Gluon package, the best way would be 
+to start with an existing package from the gluon repository and adapt it, for 
+example use the package ``gluon-web-mesh-vpn-fastd`` as a base
+
+- rename all occurrences of your example package
+- adapt the upgrade script to your needs
+- to create new config values that may be editable with ``uci`` create a file 
+  in ``/ect/config/your_new_config`` with just one section
+
+::
+
+  config main 'settings'
+
+
+- to fill this section with values from the ``site.conf`` edit the upgrade 
+  script for your package and add the same section as the filename of the config
+  file in your ``site.conf``:
+
+::
+
+  your_new_config {
+    new_value = 'example'

+Upgrading Packages from 2016.2.x
+--------------------------------
+
+The site.conf and external packages to be rewritten in some parts and Gluon now
+doesn't use LuCI for its Config Mode anymore, but our own fork
+"gluon-web", which is significantly smaller (as lots of features we don't
+need have been removed) for detailed changes see section `/web/`_.
+
+- the function ``gluon_luci.escape()`` must be replaced with ``pcdata()`` and
+  ``urlescape()`` with ``urlencode()``
+- the dependencies in the ``Makefile`` must be adapted: replace
+  ``DEPENDS:=gluon-luci-theme`` with ``DEPENDS:=gluon-web-theme``, ``luci-base``
+  with ``gluon-web`` and ``gluon-luci-admin`` with ``gluon-web-admin`` ...
+- ``i18n.translate()`` => ``translate()``
+- ``luci.template.render_string()`` =>
+  ``renderer.render_string()``
+- i.e. ``s:option(cbi.Value, "_altitude" ...`` =>
+  ``o = s:option(Value, "altitude" ...``
+- ``o.rmempty`` => ``o.optional``
+- adapt the paths: ``/lib/gluon/setup-mode/www`` =>
+  ``/lib/gluon/web/www``
+- includes: ``require 'luci.util'`` => ``require 'gluon.web.util'``, 'luci.i18n' and 'gluon.luci' => 'gluon.util'
+- ``local uci = luci.model.uci.cursor()`` => ``local uci = require("simple-uci").cursor()``
+- In ``site.mk`` all pakages with ``-luci-`` in its name must be replaced with
+  ``-web-`` (exception: ``gluon-luci-portconfig`` =>
+  ``gluon-web-network``
+- the Makefile now has to reside in a subfolder within the repository, all
+  files and folders needed for inclusion need to be in that same subfolder

+      directly in the ``mesh_vpn`` section.
