# Configuring installation behaviour of a package sfp provides various features to alter the installation behaviour of a package. These behaviours have to be applied as an additional property of a package during build time. The following section details each of the parameters that is available. {% hint style="info" %} sfp is built on the concept of immutable artifacts, hence any properties to control the installation aspects of a package need to be applied during the build command. Installation behaviour of an package cannot be controlled dynamically. If you need to alter or add a new behaviour, please build a new version of the artifact {% endhint %} --- # 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.flxbl.io/flxbl/sfp/building-artifacts/configuring-installation-behaviour-of-a-package.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.
