You preferably install it through a NuGet package. Please see http://world.episerver.com/add-ons/episerver-languages/.
Thanks a lot for your reply.
I have already installed this in my project solution but after installation when I have gone to "Add gadget" section one pop-up has opened. In the pop-up there is a search textbox. In this search textbox when I am typing the word 'languages' I am not able to find any gadget. Will you please tell me how do I add 'language' gadget by following this step?
You don't have to use the search, you typically only have 5 to 10 gadgets so scrolling to find it shouldn't be a problem. Here's a guide how to manage gadgets in edit mode http://webhelp.episerver.com/latest/platform/managing-gadgets.htm
Anyone please help me how to add Language gadgets in Episerver CMS. This is very urgent for my project.
So please help.
Thank in advance.
