# Linking source files of the TYPO3 Core {#linking-core-source}

Any file within the TYPO3 Core can be linked to their source file on GitHub using
the text role `t3src`.

You can link classes like the
[EXT:core/Classes/Pagination/SlidingWindowPagination.php (GitHub)](https://github.com/typo3/typo3/blob/main/typo3/sysext/core/Classes/Pagination/SlidingWindowPagination.php)
and any other file type like
[EXT:core/Resources/Private/Templates/ErrorPage/Error.html (GitHub)](https://github.com/typo3/typo3/blob/main/typo3/sysext/core/Resources/Private/Templates/ErrorPage/Error.html).
