When I started learning about Phoenix, I did what most developers would do … I went looking for the documentation on how to code against the existing code base. What I came to learn was that there was very little being offered in this area, so you have to ask on the forums or you have to figure it out on your own.
Don’t get me wrong, the crew over at the Phoenix Club Forum are great as there wouldn’t be a CE Phoenix without them. I strongly suggest that if you are a user of Phoenix, you should support them and Go Pro.
