 As originally planned we've overhauled the secrets configuration. In part to adapt to the new changes and also to make
 the feature much easier to understand.
 
+These changes are separated into two distinct elements:
+
+1. The secrets are now local to where they're used in the configuration instead of in a single location.
+   1. This has the advantage of if you're for example configuring PostgreSQL that you configure the username and 
+      password at the same time.
+2. The implementation specifics have been adjusted so the syntax for all secrets is generally the same.
+3. You're able to include varied secrets instead of the single secret like before.
+
+The following section shows a before and after look at the secret generation method.
+
+Before:
+
+```yaml
+name:
+  key: 'KEY_NAME'
+  value: ""
+  filename: 'FILE_NAME'
+```
+
+After:
+
+```yaml
+secret:
+  ## Disables this secret allowing you to handle it yourself in any way you see fit.
+  disabled: false
+  
+  ## Sets the name of the secret to use. The ~ value indicates the internal secret. Value will be mounted into the 
+  ## '/secrets/<secret_name>/<path>' location, where secret_name for ~ is 'internal'.
+  secret_name: ~

+  ## When using the internal secret this allows setting the value arbitrarily. Only required on the first `helm install`
+  ## or `helm upgrade`, after which it's only required to overwrite it.
+  value: ''

+  ## Key name within the secret which is the mounted location.
