# Configuration file ProjectSend uses a configuration file that includes your database connection settings as well as other personal parameters. This file is never included in the app's zip file to make sure yours is not overwritten. The location of the file is `{root}/includes/sys.config.php` It is unlikely that you'll need to create this file manually, as the installer will detect if it is missing, and launch a wizard that will help you create it while testing your database credentials at the same time. If for some reason you decide to create it yourself, a template exists at `{root}/includes/sys.config.sample.php` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.projectsend.org/about/installation/configuration-file.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
