Contributing to Mobilizon

How we collaborate

First off, thank you for considering contributing to Mobilizon!

Our aim for this project is to make you feel welcome as a contributor. We hugely value the comments and contributions of community members in the various publicly-accessible areas in use, which currently are:

How to communicate with others?

As you may know, English is not the only language in the community and communicating in various languages can be quite tricky. Some might not understand what you're saying, while others have a hard time writing in a language that is not their primary language.

If you haven't noticed yet, French is sometimes used as a language for communication in various channels. This is because a huge part of our community speaks French, as Framasoft is a French organization.

We don't want to impose French as the only language in the project, though, because we would lose a ton of potential users and contributors that can help us make Mobilizon better.

You can write what you would like to tell us in the language you're most comfortable with and then use automagic translation to translate your message to English. It's far from perfect, but if we can understand the main idea you wanted to expose, it's sufficient.

Of course, you can and should express yourself directly in English if you're confident doing so!


This project is part of Framasoft's Contributopia Campaign, creating and offering tools designed with a different set of values.

How Can I Contribute

Submitting Feature Requests, Enhancement Suggestions or Bug Reports

This section guides you through submitting โœจ feature requests, ๐Ÿ’„ enhancement suggestions, and ๐Ÿ› bug reports for Mobilizon - anything from errors and crashes, to minor improvements, to completely new features.

When you post an issue, please include as many details as possible. Fill in the issue template (available below) to help us resolve issues faster.

Before making a submission

Please go through the checklist below before posting any โœจ ๐Ÿ’„ ๐Ÿ›

  • Check if you're using the latest version of Mobilizon and all its relevant components and if you can get the desired behaviour by changing some config settings.
  • Perform a cursory search in the issue tracker to see if the enhancement has already been suggested. If it has, add a comment to the existing issue instead of opening a new one.
  • Never report security related issues, vulnerabilities or bugs including sensitive information to the issue tracker, or elsewhere in public. Instead, sensitive bugs must be sent by email to tcit plus mobilizon at framasoft dot org.


If you find a Closed issue that seems like it is the same thing that you're experiencing, open a new issue and include a link to the original issue in the body of your new one.

Suggesting Features & Enhancements

If you find yourself wishing for a feature that doesn't exist in Mobilizon, you are probably not alone. There are likely others out there with similar needs.

Open an issue providing the following information:

  • Use a clear and descriptive title for the issue to identify the suggestion.
  • Provide a description of the suggested enhancement with as many details as possible, including the steps that you imagine you (as a user) would take if the feature you're requesting existed.
  • Describe the current behaviour and explain which behaviour you would like to see instead, and why.
  • Include screenshots and animated GIFs which help demonstrate the steps or point out the parts of Mobilizon which your suggestion is related to. You can use a tool called LICEcap to record GIFs on macOS and Windows, and Silentcast or Byzanz on Linux.
  • Provide specific examples to demonstrate the enhancements. If possible, include drawings, screenshots, or GIFs of similar features in another app.
  • Explain why this enhancement would be useful to most participants of Mobilizon and isn't something that can or should be implemented as a community extension.
  • List some other communities, platforms or apps where this enhancement exists.

Reporting Bugs ๐Ÿ›

Open an issue providing the following information by filling in the issue template below, explaining the problem and including additional details to help maintainers reproduce the problem:

  • Use a clear and descriptive title for the issue to identify the problem.
  • Describe the exact steps which reproduce the problem in as many details as possible. For example, start by explaining where you started in Mobilizon, and then which actions you took. When listing steps, don't just say what you did, but explain how you did it. For example, if you moved the cursor to the end of a line, explain if you used the mouse or a keyboard shortcut, and if so which one?
  • Provide specific examples to demonstrate the steps. Include links to pages, screenshots, or copy/pasteable snippets, which you use in those examples. If you're providing snippets in the issue, use Markdown code blocks.
  • Describe the behaviour you observed after following the steps and point out what exactly is the problem with that behaviour.
  • Explain which behaviour you expected to see instead and why.
  • Include screenshots and animated GIFs which show you following the described steps and clearly demonstrate the problem. You can use LICEcap to record GIFs on macOS and Windows, and Silentcast or Byzanz on Linux.
  • If you're reporting a crash, include a crash report with error logs.
  • If the problem wasn't triggered by a specific action, describe what you were doing before the problem happened and share more information using the guidelines below.

Provide more context by answering these questions:

  • Did the problem start happening recently (e.g. after updating to a new version) or was this always a problem?
  • If the problem started happening recently, can you reproduce the problem in an older version? What's the most recent version in which the problem doesn't happen?
  • Can you reliably reproduce the issue? If not, provide details about how often the problem happens and under which conditions it normally happens.
  • If the problem is related to an event, comment or actor (eg. user or group), does the problem happen for all of them or only some? Does the problem happen only when working with local (originating from your Mobilizon instance) or remote ones, with anything specific about the object? Is there anything else special about the actors or events in question?

Include details about your configuration and environment:

  • Which version of each component are you using?
  • What's the name and version of the OS you're using?
  • Are you running in a virtual machine? If so, which VM software are you using and which operating systems and versions are used for the host and the guest?


A common misconception about contributing to free and open source projects is that you need to contribute code. In fact, itโ€™s often the other parts of a project that are most overlooked. Youโ€™ll do the project a huge favour by offering to pitch in with these types of contributions!

Even if you like to write code, other types of contributions are a great way to get involved with a project and meet other community members. Building those relationships may open up unexpected opportunities.

Do you like to design? ๐ŸŽจ

  • Restructure layouts to improve the project's usability.
  • Conduct user research to reorganise and refine the project's navigation or menus.
  • Create art for icons and app screens.

Do you like to write? โœ

  • Write and improve the project's documentation.
  • Write tutorials for the project.
  • Curate a wiki page of examples showing how the project can be used.

Do you like organising? ๐Ÿ“ฅ

  • Link to duplicate issues, and suggest new issue labels, to keep things organised.
  • Go through open issues and suggest revisiting or closing old ones.
  • Ask clarifying questions on recently opened issues to move the discussion forward.

Do you like helping people? ๐Ÿ™‹

  • Answer questions about the project on forums and other sites.
  • Answer questions for people on open issues.

Do you like to translate? ๐ŸŒ

Create an account and start translating from english to another language: you need to translate both the frontend and backend projects.


If you don't find your language in the list of translations already started, you may add your language yourself (on the bottom of the language list).

Do you like helping others code? ๐Ÿ‘

  • Review code on other people's submissions.
  • Write tutorials for how a project can be used.
  • Offer to mentor another contributor.

Do you like to code? ๐Ÿ”ฉ

  • Find an open issue to tackle.
  • Offer to help write a new feature.
  • Improve tooling, testing & deployment options.
  • Read the next section for guidelines.

Contributing Code

Unsure where to begin contributing? You can start by looking through issues tagged with:

Local development

Mobilizon can be developed locally. For instructions on how to do this, please see the documentation.

Coding & git practices

  • We use GitLab's merge requests as our code review tool.
  • We encourage any dev to comment on merge requests and we think of the merge request not as a "please approve my code" but as a space for co-developing.
  • We develop features on separate branches identified by issue numbers.
  • We don't currently use release branches or tags because we don't have release management at this phase of development.

How to make changes

  • Make your changes on a separate branch which includes an issue number e.g. 1234-some-new-feature where 1234 is the issue number where the feature is documented. Make sure the branch is based on main.
  • Do not commit changes to files that are irrelevant to your feature or bugfix.
  • Use commit messages descriptive of your changes.
  • Push to your own repository fork.
  • Create a merge request at GitLab.

Git commit messages

  • Limit the first line to 72 characters or less, referencing relevant issue numbers.
  • Be as descriptive as you want after the first line.
  • Consider starting the commit message with an applicable emoji (see Issue & Commit Categories below).

Merge requests

  • Follow the code styleguides.
  • Document new code based on the documentation styleguide.
  • Each merge request should implement ONE feature or bugfix. If you want to add or fix more than one thing, submit more than one merge request.
  • Fill in the merge request template below.
  • Include relevant issue number(s) in the merge request title.
  • Include screenshots or animated GIFs in your merge request whenever possible.
  • End all files with a newline.

Template for merge requests

  • Description of the change
  • Applicable issue numbers
  • Alternate designs/implementations
  • Benefits of this implementation
  • Possible drawbacks
  • Why should this be part of a core component?
