+The CodeIgniter framework cannot solve all of the problems that developers will encounter.
+Many users have said they love how small and fast the framework is, so we don't want to
+bloat the core framework. To bridge the gap we are releasing official packages to provide
+additional functionality that not every site will need or want.

+Shield
+******
+
+`CodeIgniter Shield <https://github.com/codeigniter4/shield>`_ is an authentication
+and authorization framework for CodeIgniter 4. It is designed to be secure, flexible,
+and easily extendable to meet the needs of many different types of websites.
+Among the many featues, it includes:
+
+* Session-based authentication
+* Personal access token authentication
+* framework for after login/register "actions" (like Two Factor Authentication, etc)
+* Role-Based Access Control with simple, flexible permissions.
+* Per-user permission overrides,
+* and more...

+Settings
+********
+
+`CodeIgniter Settings <https://github.com/codeigniter4/settings>`_ is a wrapper around
+the configuration files that allows any configuration setting to saved to the database,
+while defaulting to the config files when not custom value has been stored. This allows
+an application to ship with the default config values, but adapt as the project grows
+or moves servers, without having to touch the code.
