 deployment.
 
-## Categorising ACRs
+## ACR categories:
 
 ACRs available in Janssen Server can be broadly put into three categories. These categories are just for ease of
 understanding.
 
-### Internal Janssen Server ACR
+### 1. Internal Janssen Server ACR
 
 Janssen server will use internal ACR only if no other authentication method is set or could be invoked.
 This internal ACR, `default_password_auth`, is set to level -1. This means that it has lower
 priority than any other script. This ACR is always available and enabled on any Janssen Server deployment.
 
-This ACR is a simple user-id and password-based authentication mechanism. It'll try to authenticate the end-user
-against locally deployed backend datastore.

+### 2. Pre-packaged ACR for authenticating using external LDAP or Active Directory
 
 All Janssen Server deployments have `default_ldap_server` ACR which can be enabled to perform authentication against a
 remote LDAP-based IDP (e.g. ActiveDirectory). By default, this ACR is disabled. This ACR can only authenticate against
 LDAP-based IDP or a local LDAP.

 Using the Janssen Text base UI (TUI) configuration tool, these values can be configured by navigating to
 `Auth Server`->`clients`->`get clients`->`choose a client and press enter`->`Advanced Client Prop`. On this screen
 populate ACR values in `Default ACR` and `Allowed ACRs`:
