 Read R datasets from Python.
 
 ..
 	Github does not support include in README for dubious security reasons, so
 	we copy-paste instead. Also Github does not understand Sphinx directives.
+	.. include:: docs/index.rst
 	.. include:: docs/simpleusage.rst
+
+The package rdata offers a lightweight way to import R datasets/objects stored
+in the ".rda" and ".rds" formats into Python.
+Its main advantages are:
+
+- It is a pure Python implementation, with no dependencies on the R language or
+  related libraries.
+  Thus, it can be used anywhere where Python is supported, including the web
+  using `Pyodide <https://pyodide.org/>`_.
+- It attempt to support all R objects that can be meaningfully translated.
+  As opposed to other solutions, you are no limited to import dataframes or
+  data with a particular structure.
+- It allows users to easily customize the conversion of R classes to Python
+  ones.
+  Does your data use custom R classes?
+  Worry no longer, as it is possible to define custom conversions to the Python
+  classes of your choosing.
+- It has a permissive license (MIT). As opposed to other packages that depend
+  on R libraries and thus need to adhere to the GPL license, you can use rdata
+  as a dependency on MIT, BSD or even closed source projects.
