Getting Started with Apache Camel? This post is for you. But I am not going to dive into how to write the Camel route, there are plenty of materials out there that do a better job than me. A good place to get started is the one and only Camel Blog, it gives you all the latest and greatest news from the community. If you want to start from the basics, I highly recommend Camel in Action II Book. It has everything you need to know about writing Camel. Or join the Camel community mailing list or Zulip to ask questions, it's very friendly and welcoming.
If you are a returning Camel rider, I would go through this post, where it will get you up to speed on what to expect. Another good resource is the FAQ page. I found the majority of the getting started enquiries can be found here.
