Navigation trail: ["JMeterProjectPages"] - ["JMeterDevelopment"]

Some developer docs are already available at [ JMeter Developer Manual]. They are mostly a how-to/recipe on how to create new components.

I've found that the actually difficult bit about JMeter is to understand its architecture, which has unexpected turns. This Wiki page is an attempt at documenting it. Getting content in is more important than structuring or writing it nicely. It would be even greater if we could record some rationale for the design decisions, too.
