# Contributing to Data Migration Tool code

Contributions to the Data Migration Tool codebase are done using the fork & pull model.
This contribution model has contributors maintaining their own copy of the forked codebase (which can easily be synced with the main copy). The forked repository is then used to submit a request to the base repository to “pull” a set of changes. For more information on pull requests please refer to [GitHub Help](https://help.github.com/articles/about-pull-requests/).

Contributions can take the form of new components or features, changes to existing features, tests, documentation (such as developer guides, user guides, examples, or specifications), bug fixes or optimizations.

The Data Migration Tool development team will review all issues and contributions submitted by the community of developers in the first in, first out order. During the review we might require clarifications from the contributor. If there is no response from the contributor within two weeks, the pull request will be closed.


## Contribution requirements

1. Contributions must adhere to the [Magento coding standards](https://devdocs.magento.com/guides/v2.2/coding-standards/bk-coding-standards.html).
2. Pull requests (PRs) must be accompanied by a meaningful description of their purpose. Comprehensive descriptions increase the chances of a pull request being merged quickly and without additional clarification requests.

3. PRs which include new logic or new features must be submitted along with:
* Unit/integration test coverage
* Proposed [documentation](http://devdocs.magento.com) updates. Documentation contributions can be submitted via the [devdocs GitHub](https://github.com/magento/devdocs).
