{info}
You will find documentation about these different parts in the space associated with your Petals distribution.
A Petals distribution is an archive with Petals ESB and all of its supported and compatible tools and components. The only exception is Petals Studio, which is too big to be included in the distribution, and therefore available separately. This notion of Petals dsitribution exists since the version 4.0 of Petals ESB. Previously, elements were released in several archives.
