# ci4-cms-erp/ci4ms architecture > Architecture diagram of the GitHub repository ci4-cms-erp/ci4ms, generated by GitDiagram from its file tree, README and a sample of source files (last updated 2026-11-14). It is an AI-made overview: check details against the source. - Interactive diagram: https://gitdiagram.com/ci4-cms-erp/ci4ms - Repository: https://github.com/ci4-cms-erp/ci4ms ## Overview CI4MS is a modular CodeIgniter CMS. A visitor enters through the home route and receives public content; authenticated administrators manage content and site modules through the backend. Separate capabilities include RBAC, media and themes, notifications, migrations, backups, and signed updates. The graph combines documented product stages with source-index-supported links; it does not infer controller-to-storage calls for unsampled modules. Main entry points: [`app/Config/Events.php`](https://github.com/ci4-cms-erp/ci4ms/blob/master/app/Config/Events.php) (Event Wiring), [`app/Config/DefaultRoutes.php`](https://github.com/ci4-cms-erp/ci4ms/blob/master/app/Config/DefaultRoutes.php) (Route Loader), [`modules/Settings/Controllers/Settings.php`](https://github.com/ci4-cms-erp/ci4ms/blob/master/modules/Settings/Controllers/Settings.php) (Site Settings), [`modules/Pages/Controllers/Pages.php`](https://github.com/ci4-cms-erp/ci4ms/blob/master/modules/Pages/Controllers/Pages.php) (Page Management) ## Diagram (Mermaid) ```mermaid flowchart TD subgraph group_public["Public CMS"] node_home["Home Controller
