+### What is this?
+
+It is simple, fast and clean Django's email backend which supports async sending of emails in parallel threads. Keep it simple! It has various analogs, you can google for it yourself.
+
+### Requirements
+
+Django async email backend requires futures library. So you need to install it with `pip install futures`.
+
+### Django configuration settings
+
+This is simple backend so you need to configure django to use our backend and you can alter pool size with `EMAIL_BACKEND_POOL_SIZE`.
+
+``` python
+EMAIL_BACKEND = 'utils.email.EmailBackend'
+EMAIL_BACKEND_POOL_SIZE = 15 # default value
+```
