+RSS - Email
+-----------
+
+A simple Python script to read posts from an RSS feed and mail them to a given
+email address.
+
+To setup, copy `rssemailconfig.example.py` to `rssemailconfig.py` and edit the
+variables therein.
+
+You could run the script through cron:
+
+```cron
+*/5 * * * * (cd /path/to/rss-email.py && python3 rss-emai.py )
+```
+
+I wrote this since the `rss2email` app had some problem with authentication.
