How to contribute

Modules

If you need to have some features that we don’t have yet, we recommend that you make a module. This is a Ruby on Rails engine with some APIs specific to Decidim (for registering with the menus, integration with spaces like Participatory Processes or Assemblies, with /admin or /api, etc).

As a base you can use these modules, although check first that the version is compatible with your current Decidim version. Also you should know that until v1.0.0 We’re under development and these internal APIs can change. We recommend that you extensively test your module.

Authorizations Strategies

One specific thing regarding these kind of applications is the authorization/verification logic. Here are some examples:

Other special verifications:

Following our license

If you plan to release your application you’ll need to publish it using the same license: GPL Affero 3. We recommend doing that on GitHub before publishing, you can read more on "http://producingoss.com/en/governments-and-open-source.html#starting-open-for-govs[Being Open Source From Day One is Especially Important for Government Projects]". If you have any trouble you can contact us on Gitter.

Example applications

Since Decidim is a ruby gem, you can check out the dependent repositories to see how many applications are on the wild or tests that other developers have made. Here’s a partial list with some of the projects that have used Decidim:
