 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
