+  [[active developers/companies contribute to the project||USeCases/CommunityHealth#dev-count]]? ERP5 is a company based free software(not community based). Nexedi is the developer company. And I think there are some companies which can support/use ERP5.

-- Is there good [[developer documentation|UseCases/CommunityHealth#dev-docs]]?
-- How easy it to [[engage as a developer with the community|UseCases/CommunityHealth#dev-welcoming]]?
+- Is there good [[developer documentation|UseCases/CommunityHealth#dev-docs]]? Not so much. Source code and test code is the best documents.
+- How easy it to [[engage as a developer with the community|UseCases/CommunityHealth#dev-welcoming]]? Since ERP software is never implemented for personal use, all ERP developers do it as their job. If somebody want to engage as a developer, he/she need a real ERP project and requires a lot of experience.
