All the docs say customisation is easy, just make a child theme and edit functions.php. Then, just when you actually need some help, say, an API reference, a list of hooks, an example, ANYTHING, the docs stop and just say to turn on dev mode. WHICH DOES NOT EXIST!
Short of telepathy, how on earth is someone supposed to learn?
You may list as a bullet point that customisation is easy, but that's utter rubbish - I've been bashing my head against this for hours now, and every single avenue of attack is closed off by a total and utterly lack of documentation!
Customising Customizr is INFURIATING!
