+
+## Use Agent Context
+
+When working on this project, consult the `agent.md` file for project-specific guidelines, architecture decisions, and development patterns. This file contains curated information that will help you make better decisions aligned with the project's goals and standards.
+
+If the file does not exist, you will need to install it, by running the following command:
+
+```bash
+$ bundle install
+$ bundle exec bake agent:context:install
+```
+
+This command will set up the necessary context files that help you understand the project structure, dependencies, and conventions.
+
+## Ignoring Files
+
+The `.gitignore` file is split into two sections, separated by a blank line. The first section is automatically generated, while the second section is user controlled.
+
+While working on pull requests, you should not add unrelated changes to the `.gitignore` file as part of the pull request.
