+/**
+ * This configuration file for commitlint extends the default configuration
+ * provided by '@phase2/outline-config/commitlint.config'.
+ *
+ * The process of extending the configuration works in two steps:
+ *
+ * 1. Creating a Baseline Default:
+ *    The default configuration is a set of rules defined in
+ *    '@phase2/outline-config/commitlint.config'. These rules provide a
+ *    baseline standard for commit messages, ensuring consistency and
+ *    readability across all commits.
+ *
+ * 2. Allowing Project-Specific Alterations:
+ *    By extending the default configuration in this file, we allow for
+ *    project-specific alterations. This means that while the baseline rules
+ *    are followed, there is flexibility for the project to define its own
+ *    rules or override the default ones. This is done by adding or modifying
+ *    rules in this file.
+ *
+ * If a project decides it doesn't need the default configuration, it can
+ * completely overwrite it by not extending '@phase2/outline-config/commitlint.config'
+ * and defining its own rules from scratch.
+ *
+ * The use of the spread operator (...) before 'defaultConfig' ensures that
+ * the rules from the default configuration are correctly imported and
+ * applied in this file.
