Add custom Language in AEM 6.5

While making language copy for a site. We are provided an extensive list of languages.
This list of languages can be found at /libs/wcm/core/resources/languages

However, sometimes we need to add a custom language of own.

To do so we simply have to perform below steps
Step 1: Override languages node from /libs to /apps

Since it is highly recommended that we don't change anything in /libs directly , rather we should overlay/override them to /apps.

So first we will override the entire node structure to /apps


Step 2: Add custom language to the languages node


Step 3: Change configuration in ConfigMgr
Search and open Day CQ WCM Language Manager and change language path from libs to apps


Step 4: Restart AEM instance
The changes will not yet reflect unless we restart the AEM instance.
After restarting go to sites console and try to make a language copy for a we-retail.



Select create language copy and then click next


Then in the Target Languages dropdown, you will see your custom language added.
