Frequently asked questions

Short answers to what people usually want to know first.

Where can I find documentation for a product?
Documentation lives in each product's GitHub repository, starting from README.md. Products with a dedicated documentation site link to it from their product page. Showcases cover each product in a real deployment.
What should I do when I run into a problem or an unexpected bug?
Open an issue on the product's GitHub repository. Include steps to reproduce, expected and actual behavior, environment details, and error messages. Check existing issues first for a matching report.
What's the expected response time for bug fixes or feature requests?
We aim to respond to bug reports and feature requests within a few days. Complex issues and busy periods take longer. Pull requests with a fix or feature are welcome.
What's the cost of using these products?
All Melosso products are free and open source. You can use, modify, and share them under their respective open-source licenses at no cost.
What ways can I contribute to the products?
Submit pull requests with fixes or features, improve documentation, report issues, or answer questions from other users. Repositories with a CONTRIBUTING.md file list their own guidelines. Starring a repository on GitHub also increases its visibility.

Questions or ideas?

We're a small team. For bugs, GitHub issues are the fastest path to a fix.
