# Updating you code Because we use autoloading mechanisms, and because we use templates, there is one little step you will have to take **every single time** right after you pull the last changes from our repository: ``` composer update ``` This will ensure that all dependencies are up to date and that the autoloading mechanism is updated to find all its classes in the right places. Sadly, composer is a very slow and memory-hungry process with Chamilo, so make sure you have at least 2GB of RAM available just for that process, and that you work on something else in the meantime... --- # 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.chamilo.org/1.11.x/developer-guide/participating_to_the_development/updating_you_code.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.
