The following is a set of guidelines for contributing to crowdAI. These are just guidelines, not rules, use your best judgement and feel free to propose changes as a pull request.
This project adheres to the Contributor Covenant code of conduct. By participating, you are expected to uphold this code. Please report unacceptable behavior to [email protected].
This section guides you through submitting a bug report for crowdAI. Following these guidelines helps maintainers and the community understand your report 📝, reproduce the behavior 💻 💻, and find related reports 🔎.
Before creating bug reports, please check this list as you might find out that you don't need to create one. When you are creating a bug report, please include as many details as possible. If you'd like, you can use this template to structure the information.
- Check the [FAQs on the forum](TO-DO: Addline) for a list of common questions and problems.
- Perform a cursory search to see if the problem has already been reported. If it has, add a comment to the existing issue instead of opening a new one.
Bugs are tracked as GitHub issues. After going through the necessary first steps, you can create an issue on and provide the following information.
Explain the problem and include 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 how you started crowdAI, e.g. which command exactly you used in the terminal, or how you started crowdAI otherwise. When listing steps, don't just say what you did, but explain how you did it.
- Provide specific examples to demonstrate the steps. Include links to files or GitHub projects, or copy/pasteable snippets, which you use in those examples. If you're providing snippets in the issue, use Markdown code blocks.
- Describe the behavior you observed after following the steps and point out what exactly is the problem with that behavior.
- Explain which behavior you expected to see instead and why.
- Include screenshots and animated GIFs which show you following the described steps and clearly demonstrate the problem. If you use the keyboard while following the steps, record the GIF with the Keybinding Resolver shown. You can use this tool to record GIFs on macOS and Windows, and this tool or this tool on Linux.
- If you're reporting a crash, include a crash report with a stack trace from the operating system. Include the crash report in the issue in a code block, a file attachment, or put it in a gist and provide link to that gist.
- If the problem is related to performance, include a CPU profile capture and a screenshot with your report.
- 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 of crowdAI) or was this always a problem?
- If the problem started happening recently, can you reproduce the problem in an older version of crowdAI? What's the most recent version in which the problem doesn't happen? (TO-DO: Add links to older versions of crowdAI)
- Can you reliably reproduce the issue? If not, provide details about how often the problem happens and under which conditions it normally happens.
Include details about your configuration and environment:
- Which version of crowdAI are you using? (TO-DO: Add how to figure out the exact version of crowdAI)
- Are you running crowdAI 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?

We welcome contributions, and are especially interested in welcoming Beginner issues.
For installation, prerequisites include postgresql and rvm. Click here for a complete list and instructions.
- Fork our repo from https://github.com/crowdAI/crowdai.
- In the console, download a copy of your forked repo with
git clone https://github.com/your_username/crowdai.gitwhereyour_usernameis your GitHub username. - Enter the new crowdai directory with
cd crowdai. - Install gems with
bundle installfrom the rails root folder, to install the gems you'll need. You may need to first runbundle updateif you have older gems in your environment from previous Rails work. - Make a copy of
config/application.yml.exampleand place it atconfig/application.yml. - Run
rake db:migrateto migrate schema to our database then runrake db:seedto seed our database created using postgres. - Run the redis server using
sudo systemctl start redis. - Run the webpack-dev-server using
./bin/webpack-dev-server. - By default, start rails with
rails serverfrom the Rails root and open http://localhost:3000 in a web browser.
For some, it will be necessary to prepend your gem-related commands with bundle exec.
For example, bundle exec rails server.
Adding bundle exec ensures you're using the version of passenger you just installed with Bundler.
bundle exec rake db:migrate, bundle exec rake db:seed are other examples of where this might be necessary.

When contributing to an open source project you might hit some problems, have some of those Eureka moments, and you simply might want to have a quick chat with us. You can always reach out to us at [email protected] and you are always welcome to join the crowdAI Community banter on our Gitter channel at https://gitter.im/crowdAI/Lobby
As a young open source organization we continue to learn a lot along the way. Writing this Contributors Guidelines was one such learning experience, where we learnt so much from the Contributors Guidelines of one of our favorite open source projects, Atom.
