+### Logging Options
+```js
+// Use this to get more detailed logging when posting
+// Errors will always be logged
+blapi.setLogging({
+  extended: true
+});
+```
+
+```js
+// If you have your own logger that you want to use pass it to BLAPI like so (the variable "log" in this example)
+// !Important: The logger needs to export the following methods: log.info(), log.warn() and log.error()
+blapi.setLogging({
+  extended: true,
+  logger: log
+})
+```
+```js
+// If you want to pass in only your custom logger but dont want extended logging to be enabled you would do:
+blapi.setLogging({
+  logger: log
+})
+```
