+========================
+Report Wkhtmltopdf Param
+========================
+
+This module allows you to add new parameters for a paper format which are
+then forwarded to wkhtmltopdf command as arguments. To display the arguments
+that wkhtmltopdf accepts go to your command line and type 'wkhtmltopdf -H'.
+
+A commonly used parameter in Odoo is *--disable-smart-shrinking*, that will
+disable the automatic resizing of the PDF when converting. This is
+important when you intend to have a layout that conforms to certain alignment.
+It is very common whenever you need to conform the PDF to a predefined
+layoyut (e.g. checks, official forms,...).
+
+
+Usage
+=====
+
+#. Go to *Settings* and press 'Activate the developer mode (with assets)'
+#. Go to *Settings - Technical - Reports - Paper Format*
+#. Add additional parameters indicating the command argument name (remember to
+  add prefix -- or -) and value.
