 `vip-go-ci` is a PHP-program that can be called for latest commits pushed to Pull-Requests on GitHub, looking for problems in the code using PHP linting, [PHPCS](https://github.com/squizlabs/PHP_CodeSniffer/), and a [SVG scanner](https://github.com/Automattic/vip-go-svg-sanitizer) -- and then posting back to GitHub comments and reviews, detailing the issues found. `vip-go-ci` can also automatically approve Pull-Requests that contain already-approved files (registered in a special database) and/or contain file-types that are approvable by default.
 
-`vip-go-ci` is to be called from the commandline, using several arguments specifying the repository and commit-ID to scan, and various other options. During execution, `vip-go-ci` will provide a detailed log of its actions and what it encounters. The program expects a fully-functional git-repository to be stored locally on the computer running it, were from it can extract various information.

 It has different behaviours for different scanning-methods. For PHP linting, it will loop through every file existing in the code-base, and post a generic Pull-Request comment for any issues it finds with the PHP-code. In case of PHPCS scanning, however, it will scan only the files affected by the Pull-Request using PHPCS, and for any issues outputted by PHPCS, post a comment on the commit with the issue, in the form of a 'GitHub Review' (this includes inline comments and a review-message). SVG scanning behaves similar to PHPCS scanning. What scanning is performed can be customised on the command-line.
