# Setup your IDE {#setup-ide}

In the Appendix, you can find some hints that might be useful for
[PhpStorm: Setup](https://docs.typo3.org/permalink/t3contribute:phpstorm-setup).

## Coding Guidelines {#coding-guidelines}

There is an `.editorconfig` file in the TYPO3 core repository.
See [https://editorconfig.org/](https://editorconfig.org/) for more information.

Please note that the rules in `.editorconfig` are very minimal. So, additionally,
setup your editor / IDE to use the recommendation as described in the
[Coding Guidelines of TYPO3](https://docs.typo3.org/m/typo3/reference-coreapi/main/en-us/CodingGuidelines/Index.html#cgl).

See [PhpStorm setup CGL](https://docs.typo3.org/permalink/t3contribute:phpstorm-setup-cgl) for information about setting up
PhpStorm to comply with the Coding Guidelines.
