 ![Dotkernel Admin File Structure!](https://docs.dotkernel.org/img/admin/file-structure-dk-admin.jpg)
 
-## Main directories
-
-* `bin` - Executable files from CLI
-* `config` - Various configuration files
-* `data` - Should contain project-related data (AVOID storing sensitive data on VCS)
-* `log` - Storage of log files generated by dot-error-log library
-* `public` - Publicly visible files. The webserver need to have this folder as www-document root folder.
-* `src` - Should contain the source code files
-* `test` - Should contain the test files
-
 ## Special purpose folders
 
-* `.github`  - Contains workflow files
+* `.github` - Contains GitHub workflow files
 * `.laminas-ci` - Contains laminas-ci workflow files
 
-## `src` directory
+## `bin` folder
 
-This directory contains all source code related to the Module.
-It should contain the following directories, if they are not empty:
+This folder contents are
 
-* Handler - Action classes (similar to Controllers but can only perform one action)
-* Entity - Database entities
-* Service - Service classes
-* Collection - Database entities collections
-* Repository - Entity repository folder
+* `clear-config-cache.php` - Removes the config cache file `data/cache/config-cache.php`; available only when development mode is enabled
+* `cli.php` - Used to build console applications based on [laminas-cli](https://github.com/laminas/laminas-cli)
+* `doctrine` - Used by the doctrine fixtures to populate the database tables
 
-> The above example lists just a part of the directories in a project, but it should give you an idea of what the structure should look like.
+## `config` folder
 
-Other classes in the `src` directory may include `InputFilter`, `EventListener`, `Helper`, `Command`, `Factory` etc.
+This folder contains all application-related config files:
 
-The `src` directory should also contain 2 files:
+* `cli-config.php` - Command line interface configuration used by migrations, fixtures, crons
+* `config.php` - Registers ConfigProviders for installing packages
+* `container.php` - Main service container that provides access to all registered services
+* `development.config.php.dist` - Activates debug mode; gets symlinked as `development.config.php` when enabling development mode
+* `migrations.php` - Configuration for database migration, like migration file location and table to save the migration log
+* `pipeline.php` - Contains a list of middlewares, in the order of their execution
+* `twig-cs-fixer.php` - Configuration file for Twig code style checker/fixer
 
-* `ConfigProvider.php` - Provides configuration data
-* `RoutesDelegator.php` - Module main routes entry file
+### `config/autoload` folder
 
-## `templates` directory for modules
+This folder contains all service-related local and global config files:
 
-This directory contains the template files, used for example to help render e-mail templates.
+* `app.global.php` - Configures basic app variables
+* `authentication.global.php` - Defines the Admin identity
+* `authorization.global.php` - Configures permissions for user roles
+* `authorization-guards.global.php` - Configures access per route for user roles
+* `cli.global.php` - Configures cli
+* `cors.global.php` - Configures Cross-Origin Resource Sharing, like call origin, headers, cookies
+* `dependencies.global.php` - Config file to set global dependencies that should be accessible by all modules
+* `development.local.php.dist` - Gets symlinked as `development.local.php` when enabling development mode; activates error handlers
+* `doctrine.global.php` - Configuration used by Object–relational mapping
+* `error-handling.global.php` - Configures and activates error logs
+* `local.php.dist` - Local config file where you can overwrite application name and URL
+* `local.test.php.dist` - Local configuration for functional tests
+* `mail.local.php.dist` - Mail configuration; e.g. sendmail vs smtp, message configuration, mail logging
+* `mezzio.global.php` - Mezzio core config file
+* `navigation.global.php` - Configures the top menu
+* `session.global.php` - Configures the session
+* `templates.global.php` - dotkernel/dot-twigrenderer config file
 
-> Dotkernel Admin uses `twig` as Templating Engine.
-> All template files have the extension `.html.twig`.
+## `data` folder
+
+This folder is a storage for project data files and service caches.
+It contains these folders:
+
+* `cache` - Cache for e.g. Twig files
+* `doctrine` - Database migrations and fixtures
+* `geoip` - Holds the GeoLite2 databases
+* `lock` - Contains lock files generated by [`dotkernel/dot-cli`](https://docs.dotkernel.org/dot-cli/v3/lock-files/)
+
+> AVOID storing sensitive data on the repository!
+
+## `log` folder
+
+This folder stores daily log files.
+When you access the application from the browser, (if not already created) a new log file gets created in the format specified in the `config/autoload/error-handling.global.php` config file under the `stream` array key.
+
+## `public` folder
+
+This folder contains all publicly available assets and serves as the entry point of the application:
+
+* `css` and `js` - Contains the css and js file(s) generated by the webpack (npm) from the assets folder
+* `fonts` and `images` - Contain the font and image file(s) copied by the webpack (npm) from the assets folder
+* `uploads` - a folder that normally contains admin avatar images
+* `.htaccess` - server configuration file used by Apache web server; it enables the URL rewrite functionality
+* `index.php` - the application's main entry point
+* `robots.txt.dist` - a sample robots.txt file that allows/denies bot access to certain areas of your application; activate it by duplicating the file as `robots.txt` and comment out the lines that don't match your environment
 
-## `data` directory
+## `src` folder
 
-This directory contains project-related data, like cache and file uploads.
+This folder contains a separate folder for each Module.
 
-We recommend using the following directory structure:
+These are the modules included by default:
 
-* `data/cache` - Location where caches are stored
-* `data/doctrine` - Fixtures and migrations
-* `data/lock` - Lock files generated by [dotkernel/dot-cli](https://docs.dotkernel.org/dot-cli/v3/lock-files/)
+* `Admin` - Contains functionality for managing users with `admin` role; note these are users save in the `admin` database table
+* `App` - Contains core functionality, from authentication, to rendering, to error reporting
+* `Setting` - Contains functionality for saving and reading display settings
+
+### Module contents
+
+Each Module folder, in turn, should contain the following folders, unless they are empty:
+
+* `src/Controller` - Action classes
+* `src/Entity` - Used by database entities
+* `src/Repository` - Entity repository folder
+* `src/Service` - Service classes
+
+The above example is just some of the folders a project may include, but they should give you an idea about the recommended structure.
+Other classes the `src` folder may include are `InputFilter`, `EventListener`, `Helper`, `Command`, `Factory` etc.
+
+The `src` folder in each Module folder normally also contains these files:
+
+* `ConfigProvider.php` - Configuration data for the module
+* `OpenAPI.php` - Detailed descriptions for each endpoint in the OpenAPI format
+* `RoutesDelegator.php` - Module specific route registrations
+
+### `templates` folder for modules
+
+This folder contains the template files, used for example to help render e-mail templates.
+
+> `twig` is used as Templating Engine.
+> All template files have the extension `.html.twig`.
