Easy Method to update the revised VBA modules in Excel 2013

Hello All,
I have created an VBA enabled template to automate few things which is being used by nearly 40 people everyday.Also this template has few data in it always.
I keep revising this the VBA codes every now and then (Based on suggestions received) and then send the revised template to all 40 people. In turn, these 40 people copy their existing data from old to new template which takes some time.

I actually want to know, is there any better way to update these revised modules to all 40 users in one shot..? I mean, some patches kind of a thing.?
Instead sending revised template verytime, i can send these patches and ask them to update it. By this, all user don't have to move their data.

I hope i am clear with my concern.

Please help and provide me Step by step process to do this.

Thanks,
Madvesh

No, not really. One possible approach is to create your code as an add-in and just get the users to install the newer version of it.

A more complex idea is one that Bruce McPhearson came up with on his Excel Ramblings blog - he uses github to host his code then adds code to the workbook to pull this down, this is somewhat more advanced though

Can you please explain detailed steps to create add-in..? and how i can make use of this to fix my issue?
