+### Consumers
+
+```Bash
+JOB_CONCURRENCY=5
+...
+MAX_CONNECTIONS_PER_TORRENT=10
+...
+CONSUMER_REPLICAS=3
+```
+
+These are totally subjective to your machine and network capacity. The above default is pretty minimal and will work on most machines.
+
+`JOB_CONCURRENCY` is how many films and tv shows the consumers should process at once. As this affects every consumer this will likely cause exponential
+ strain on your system. It's probably best to leave this at 5, but you can try experimenting with it if you wish.
+
+`MAX_CONNECTIONS_PER_TORRENT` is how many peers the consumer will attempt to connect to when it is trying to collect metadata.
+Increasing this value can speed up processing, but you will eventually reach a point where more connections are being made than
+your router can handle. This will then cause a cascading fail where your internet stops working. If you are going to increase this value
+then try increasing it by 10 at a time.
+
+> Increasing this value increases the max connections for every parallel job for every consumer. For example
+> with the default values above this means that Knight Crawler will be on average making `(5 x 3) x 10 = 150` connections at any one time.

+
+`CONSUMER_REPLICAS` is how many consumers should be started. This is the ultimate decider in how fast you will be able to
+add films and tv shows to your database. However, this is also going to be the most intensive service you will run.
+The default of 3 is a reasonable starting amount. It will work on almost every system.
