 The responsibilities of these tools are:
 - To copy files from the `node-modules` folder to the `media` folder.
 - Do any transformations on the copied files.
-- Update the version numbers on the XML files of the TinyMCE and CodeMirror editors.
-- Copy files from the `build/media_source` folder to the `media` folder.
+- Copy files from the `media_source/` folder to the `media` folder.
 - Transform any modern JS to ES2017 and transpile it to ES5.
 - Transform any SCSS file to the respective CSS file.
 
 For some of these operations, conventions were established to simplify and speed up the process.
 
-## Javascript
-There are three options here:
-- Modern Javascript files must have an extension `.es6.js`.
-  This allows ESLint to check the code style, Joomla is using the Airbnb preset https://github.com/airbnb/javascript.
-  It also instructs Rollup to do the transforms for ES2017. This step creates both normal and minified files.
-  Production code WILL NOT have the `.es6` part for ES2017+ files.
+Read more at [CMS Media source](../media_source/README.md).
 
-- Web Component Javascript files must have an extension `.w-c.es6.js`.
-  This allows ESLint to check the code style and instructs Rollup to do the transforms for ES2017. This step creates normal and minified files. The difference with the `.es6` files is that the tools will automate the minification of the CSS (assuming that the appropriate SCSS file exists), which is then injected into the JS file in place of the placeholder `{{CSS_CONTENTS_PLACEHOLDER}}` (ie: `build/media_source/system/js/joomla-core-loader.w-c.es6.js`)
-  Production code WILL NOT have the `.w-c.es6` part for ES2017+.
 
-- Legacy Javascript files must have an extension `.es5.js`.
-  This instructs ESLint to skip checking this file.
-  Also, it instructs the tools to create a minified version (production code WILL NOT have the `.es5` part)
-
-- Javascript files with only an extension `.js`.
-  These files will be ignored by the build tools.
-
-## SCSS
-- SCSS files starting with `_` will not become entry points for SCSS.
-  SCSS files will be transformed to CSS, both normal and minified versions.
-
-## CSS
-- CSS files will only get minified.
+## NPM Commands
 
+- `npm run builders-list` Show list of available builders in order of execution.
+- `npm run build` Build assets with production env. Extra arguments are required. Check [CMS Media source](../media_source/README.md#building-assets).
+- `npm run build:dev` Build assets with development env. Extra arguments are required. Check [CMS Media source](../media_source/README.md#building-assets).
+- `npm run watch` Start files watcher for specified asset with production env. Example `npm run watch -- -n com_content` for `com_content` assets.
+- `npm run watch:dev` Start files watcher for specified asset with development env.
+- `npm run lint:js` Checks the code style for the JavaScript/Vue files
+- `npm run lint:testjs` Checks the code style for the JavaScript/Vue files under `tests/System` used for testing.
+- `npm run lint:css` Checks the code style for all SCSS files.
+- `npm run gzip` Creates `.gz` files for all the `.min.js` and `.min.css`.
 
-## NPM Commands
-- `npm run build:js`: compiles ALL the JS (excluding Bootstrap and Media Manager).
-- `npm run build:js -- build/media_source/com_actionlogs`: compiles ALL the JS ONLY in the folder `build/media_source/com_actionlogs`.
-- `npm run build:css`: compiles ALL the SCSS.
-- `npm run build:css -- templates/cassiopeia`: compiles ALL the SCSS ONLY in the folder `templates/cassiopeia`.
-- `npm run build:bs5`: Builds the Bootstrap Javascript components.
-- `npm run build:com_media`: Builds the Media Manager Vue Application.
-- `npm run build:com_media:dev`: Builds the Media Manager Vue Application but in DEV mode, (no minification, no es5 and all flags for the vue devtools)
-- `npm run lint:js`: Checks the code style for all the Javascript/Vue files.
-- `npm run lint:js -- --fix`: Checks and fixes the code style for all the Javascript/Vue files (might not fix everything).
-- `npm run lint:css`: Checks the code style for all SCSS files.
-- `npm run lint:css -- --fix`: Checks and fixes the code style for all SCSS files (might not fix everything).
-- `npm run gzip`: Creates `.gz` files for all the `.min.js` and `.min.css`.
-- `npm run versioning`: Creates the correct version hash for all the assets inside the joomla.asset.json files (excluding templates).
 
 ## Working Efficiently with the Joomla Build Tools
 
 Usually, the scope of a single contribution to the project should be limited. For example: fixing a CSS bug, a Javascript bug, some Markup, or a bug that involves changes in all these areas. The build tools were created so that you spend less time on compiling assets than testing a possible solution.
 
-*Embrace the watchers*
-Let the computer help you succeed faster and safer. There are 2 watchers at the moment: one for the Media Manager (client app based on VueJS) and another one that handles templates and the source (build) folder.
-
-Assuming that you are working on the Media Manager, you can run in your terminal (already in the root folder of the Joomla repo) `npm run watch:com_media`. This watcher will automatically recompile the app on every save (there is a debounce of 0.3s, so if you have autosave it will be a clever way to minimise the wait).
-
-Assuming that you are working on the Web Authentication JavaScript, you can run in your terminal (already in the root folder of the Joomla repo) `npm run watch -- build/media_source/plg_system_webauthn`. This watcher will automatically recompile any JavaScript file inside the folder `build/media_source/plg_system_webauthn/js` on every save. But there's more! Since you asked the watcher to check the parent folder (eg `build/media_source/plg_system_webauthn`), you can also edit the SCSS files in the `build/media_source/plg_system_webauthn/scss` or the CSS files in `build/media_source/plg_system_webauthn/css`. The same example for editing some SCSS in the Cassiopeia template would require a command like: `npm run watch -- templates/cassiopeia/scss`.
-
 Once you get your code doing what it is meant to do, make sure that you check you are not breaking any of the Code Style rules by running `npm run lint:css -- --fix` and `npm run lint:js -- --fix` (the `-- --fix` will try to fix anything that's not trivial).
 
 Happy coding

+# CMS Media source
+
+The folder contains source files of CMS client-side resources (Stylesheets, JavaScripts, Images and other assets) needed for extensions to work.
+Each folder is for a specific extension with a few exceptions like `vendor`, `system`.
+
+## Building assets
+
+Before using the assets they must first be built/compiled and placed under `media/` folder.
+
+Following command helps to build, they will call builder associated with each asset:
+- `npm run build -- -a` Build all assets. Will go through all resources and will build each asset.
+- `npm run build -- -n <resource_name>,<resource_name>` Build only specific asset.
+
+Additionally, each builder may provide their own task, that can be executed separately without running the whole rebuild.
+In default configuration the builder uses following tasks:
+- `clear` remove all associated files from `media/`.
+- `copy` copy static files to `media/`
+- `css` process Stylesheets files. Copy or compile to CSS when needed (example for SCSS etc.).
+- `js` process JavaScript files. Copy or compile to JS when needed (example for `.es6.js` and `.vue` etc.).
+- `gzip` prepare compressed version of css,js files.
+
+To execute specific task use `-t` argument:
+- `npm run build -- -a -t <task_name>,<task_name>` Will apply specified task to all asset builders.
+- `npm run build -- -n <resource_name>,<resource_name> -t <task_name>,<task_name>` Will apply specified task to specified asset builders.
+
+Use watchers while developing an extension allows to automatically refresh the assets while editing.
+- `npm run watch -- -n <resource_name>` Will start watching files changes for specific asset.
+
+## Adding new assets
+
+To add new resource follow next steps:
+- Create folder under `media_source/` with name of future asset. Example for `com_example` it will be `media_source/com_example/`.
+- Add Stylesheets, JavaScript and other needed files for the asset.
+- Add the resource name in to `build/build-modules-js/builders-registry.mjs` into the list of `builders` so CLI know it exists.
+- (Optionally) When need extra processing add custom builder into the root of the newly created folder `media_source/com_example/builder.mjs`.
+- Source files of complex Application (for example Vue based script) place under `src/` like `media_source/com_example/src/` and use custom builder to build the Applictaion.
+
+Done. And do not forget to run build.
+
+### Note about JavaScript and Stylesheets
+
+#### Javascript
+
+- Modern JavaScript files must have an extension `.es6.js`.
+  This allows ESLint to check the code style, Joomla is using the Airbnb preset https://github.com/airbnb/javascript.
+  It also instructs Rollup to do the transforms for ES2017. This step creates both normal and minified files.
+  Production code WILL NOT have the `.es6` part for ES2017+ files.
+
+- Legacy JavaScript files must have an extension `.es5.js`.
+  This instructs ESLint to skip checking this file.
+  Also, it instructs the tools to create a minified version (production code WILL NOT have the `.es5` part)
+
+
+#### SCSS
+- SCSS files starting with `_` will not become entry points for SCSS.
+  SCSS files will be transformed to CSS, both normal and minified versions.
+
+### Custom builder
+
+By default, each resource uses `DefaultModuleBuilder` class to build its asset.
+However, each resource may have own `builder.mjs` script with custom logic.
+To use custom builder add `builder.mjs` with custom logic in to the root of the resources' folder.
+
+#### Anatomy of custom builder
+
+Each builder receives the base path (path to `media_source/`) and target path (path to `media/`) as input, also cmd options.
+The builder should provide list of tasks which it is able to run and expose public methods for each task to do so.
+
+**ATTENTION**: While coding the custom builder avoid writing in to folders outside the current asset scope. This could lead to unexpected collisions.
+
+Example builder:
+
+```javascript
+export default class ExampleModuleBuilder
+{
+	tasksBuild = ['clear', 'copy', 'css', 'js'];
+	tasksExtras = ['gzip'];
+
+	constructor(name = '', basePath = '', targetPath = '', options = {}) {
+		if (!name) {
+			throw new Error(`Argument "name" is required for ModuleBuilder.`);
+		}
+
+		if (!basePath || !targetPath) {
+			throw new Error(`Arguments "basePath" and "targetPath"  is required for "${name}" ModuleBuilder.`);
+		}
+
+		this.name = name;
+		this.basePath = path.join(basePath, name);
+		this.targetPath = path.join(targetPath, name);
+		this.options = options;
+	}
+
+	getAllTasks() {
+		return [ ...this.tasksBuild, ...this.tasksExtras ];
+	}
+
+	getBuildTasks() {
+		return this.tasksBuild;
+	}
+
+	// The methods to execute each task
+	async clear() {}
+	async copy() {}
+	async css() {}
+	async js() {}
+	async gzip() {}
+}
+```
+
+The list of tasks is not strict, and depending on the builder needs.
+However, it is required the builder to implement `getBuildTasks()` so the main script knows which tasks need to run while running the complete build.
+Method `getAllTasks()` is optional, needed only when builder have tasks that can be executed from CLI but which does not participate in the complete build.
+
+To simplify the coding it is possible to extend `DefaultModuleBuilder` class.
+
+```javascript
+import DefaultModuleBuilder from '../../build/build-modules-js/builder/default-module-builder.mjs';
+
+export default class ExampleModuleBuilder extends DefaultModuleBuilder {
+	async js() {
+		await super.js();
+
+		// Run custom code
+	}
+}
+```
