There are a lot of addons in Plone for sliders/banners/teasers. We thought there should be a better one and created collective.behavior.banner.
Like many ad-dons it has not yet been released on pypi but only exists as code on github.
The training-buildout hold a section [sources] that tells buildout to download a specific ad-don not from pypi but from some code repository (usually github):
collective.behavior.banner = git https://github.com/collective/collective.behavior.banner.git firstname.lastname@example.org:collective/collective.behavior.banner.git rev=af2dc1f21b23270e4b8583cf04eb8e962ade4c4d
Pinning the revision saves us from being surprised by changes in the code we might not want.
After adding the source, we need to add the egg to buildout:
And rerun ./bin/buildout
