+What is lxml?
+=============
+
+lxml is the most feature-rich and easy-to-use library for processing XML and HTML in the Python language.
+It's also very fast and memory friendly, just so you know.
+
+For an introduction and further documentation, see `doc/main.txt`_.
+
+For installation information, see `INSTALL.txt`_.
+
+
+Support the project
+-------------------
+
+Most people who use lxml for their daily work do so because they like using it.
+If you like it, send us a flattr.

+
+However, if you are using lxml for your work and feel like you should
+give a bit of your own benefit back to support the project, consider
+sending us money through PayPal.  Please read the Legal Notice below.

+
+Note that Flattr keeps 10% of the money for itself, so do not send
+any larger amounts through Flattr.  Use PayPal for donations instead,
+or contact `Stefan Behnel`_ for other ways to support the lxml project,
+as well as commercial support, customisations and trainings.
