I'm developing new WP theme and would wont to make it autoupdateble.
Coulden't find eny info in WP Docs, foud solution in some API, but that api removes all existing files in WP theme and delivers a new one.
But I'm looking for something that can change only 1 folder in WP theme.
Can you halp me with that, some doc from WP or something else to reed (perhaps PHP) how to deal with my problem!?
