 ## Frontend development
 
 ### Classic environment
-
 A complete guide can be found at the following [link](https://www.home-assistant.io/developers/frontend/). It describes a short guide for the build of project.
 
+### Docker environment
+It is possible to compile the project and/or run commands in the development environment having only the [Docker](https://www.docker.com) pre-installed in the system. On the root of project you can do:
+* `sh ./script/docker_run.sh build` Build all the project with one command
+* `sh ./script/docker_run.sh bash` Open an interactive shell (the same environment generated by the *classic environment*) where you can run commands. This bash work on your project directory and any change on your file is automatically present within your build bash.
+
+**Note**: if you have installed `npm` in addition to the `docker`, you can use the commands `npm run docker_build` and `npm run bash` to get a full build or bash as explained above

-# Bundling Home Assistant Frontend
-
-The Home Assistant build pipeline contains various steps to prepare a build.
-
-- Generating icon files to be included
-- Generating translation files to be included
-- Converting TypeScript, CSS and JSON files to JavaScript
-- Bundling
-- Minifying the files
-- Generating the HTML entrypoint files
-- Generating the service worker
-- Compressing the files
-
-## Converting files
-
-Currently in Home Assistant we use a bundler to convert TypeScript, CSS and JSON files to JavaScript files that the browser understands.
-
-We currently rely on Webpack but also have experimental Rollup support. Both of these programs bundle the converted files in both production and development.
-
-For development, bundling is optional. We just want to get the right files in the browser.
-
-Responsibilities of the converter during development:
-
-- Convert TypeScript to JavaScript
-- Convert CSS to JavaScript that sets the content as the default export
-- Convert JSON to JavaScript that sets the content as the default export
-- Make sure import, dynamic import and web worker references work
-  - Add extensions where missing
-  - Resolve absolute package imports
-- Filter out specific imports/packages
-- Replace constants with values
-
-In production, the following responsibilities are added:
-
-- Minify HTML
-- Bundle multiple imports so that the browser can fetch less files
-- Generate a second version that is ES5 compatible
-
-Configuration for all these steps are specified in [bundle.js](bundle.js).
