+            [`Redis`](http://redis.io/) is an open-source, in-memory key-value data structure store. Redis offers a set of versatile in-memory data structures (strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes, and streams) that allow the creation of many custom applications. Key use cases for Redis include database, caching, session management and message broker.
+
+            Lowdefy integrates with Redis using the one of the recommended [Node.js clients (node-redis)](https://github.com/redis/node-redis).

+
+            Connection types:
+              - Redis
+
+            ### Redis
+
+            #### Properties
+            - `connection: object | string `: __Required__ - Connection object or string to pass to the [`redis client`](https://github.com/redis/node-redis) redis client.
+
+            The connection object accepts will be passed to the redis client verbatim, so check out the [configuration instructions](https://github.com/redis/node-redis/blob/master/docs/client-configuration.md).
+
+            #### Examples
+
+            ###### Redis with connection object:
+            ```yaml
+            connections:
+              - id: redis
+                type: Redis
+                properties:
+                  connection:
+                    username: 
+                      _secret: REDIS_USERNAME
+                    password: 
+                      _secret: REDIS_PASSWORD
+                    database:
+                      _secret: REDIS_DATABASE
+                    socket:
+                      host:
+                        _secret: REDIS_HOST
+                      port:
+                        _secret: REDIS_PORT
+            ```
+            Environment variables:

+            LOWDEFY_SECRET_REDIS_DATABASE = 4
+            LOWDEFY_SECRET_REDIS_HOST = redis.server.com
+            LOWDEFY_SECRET_REDIS_PORT = 5000
+            ```
+
+            ###### Redis with connection string:
