+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.
+
+
+*****
+Cache
+*****
+
+We provide a library with `PSR-6 and PSR-16 Cache Adapters <https://github.com/codeigniter4/cache>`_
+for CodeIgniter 4. This is not required for use, since CodeIgniter 4 comes with a fully-
+functional cache component. This module is only for integrating third-party packages
+that rely on the PSR interface provisions.
+
+
+******
+DevKit
+******
+
+`CodeIgniter DevKit <https://github.com/codeigniter4/devkit>`_ provides all of the
+development tools that CodeIgniter uses to help ensure quality code, including
+our coding standard, static analysys tools and rules, unit testing, data generation,
+file-system mocking, security advisories, and more. This can be used in any of
+your personal projects or libraries to get you rapidly setup with 17 different tools.
+
+
+***************
+Coding Standard
+***************
+
+The `CodeIgniter Coding Standard <https://github.com/CodeIgniter/coding-standard>`_
+holds the official coding standards of CodeIgniter based on PHP CS Fixer and powered by
+Nexus CS Config. This can be used in your own projects to form the basis of a
+consistent set of style rules that can be automatically applied to your code.
