Magento XML build-up in plain english?

问题

I've been reading about Magento and I understand the core flow of its request cycle etc.. (configuration based MVC and class overriding and such..) However, I cannot seem to find a good article/documentation on the specifics of things - especially when it comes to different nodes required to build the config.xml for custom module etc..OR anything on XML build-up. If anybody could direct me to the "real good stuff"..article, documentation, tutorial..anything please.

Thanks
