Description

Its a bit out of date
https://camel.apache.org/manual/latest/building.html

Also remove the stuff about mvn idea:idea as we dont really support this way. Just open the pom.xml file from IDEA.

And add note about not opening the entire source code as its a big project, but open each module you work on individually.

And update the pre-requisitie and so on.
