 ### Caching
 
-In-memory caching of `details` data is provided by default via the `cachetools <https://cachetools.readthedocs.io/en/latest/>`_ library. This uses an LRU (least recently used) cache with a TTL (time to live) by default. This means that values will be cached for the specified duration; if the cache's max size is reached, cache values will be invalidated as necessary, starting with the oldest cached value.

+### Lite API
+
+The library gives the possibility to use the [Lite API](https://ipinfo.io/developers/lite-api) too, authentication with your token is still required.

+The IP details returned are slightly different from the Core API middleware, though the arguments are identical.

+To use it add `'ipinfo_django.middleware.IPinfoLiteMiddleware'` to `settings.MIDDLEWARE` in `settings.py`:

+```python
+MIDDLEWARE = [
+  'django.middleware.security.SecurityMiddleware',
+  'django.contrib.sessions.middleware.SessionMiddleware',
+  ...
+  'ipinfo_django.middleware.IPinfoLiteMiddleware',

+```
+
+We also provide an async Lite API middleware to be used under ASGI. Use `'ipinfo_django.middleware.IPinfoAsyncLiteMiddleware` in that case.
