+Auto-generating a locustfile
+============================
+
+You can use `har2locust <https://github.com/SvenskaSpel/har2locust>`_ to generate locustfiles based on a browser recording (HAR-file).
+
+It is particularly useful for beginners that are not used to writing their own locustfile, but also highly customizable for more advanced use cases.
+
+.. note::
+
+    har2locust is still in beta. It may not always generate correct locustfiles, and its interface may change between versions.
