Home Assistant Development Documentation
This is the source for the Home Assistant Development documentation.
Updating the docs
Documentation is built using Docusaurus.
Editing on GitHub
Small changes to text can be made directly on GitHub. At the bottom of each page there is an "Edit This Page" link which will load the document in GitHub ready for changes. This method doesn't easily allow for additional documents or images to be added.
Preparing a local environment
There are two options for developing the documentation on a local system.
Visual Studio Code and devcontainer
The easiest way to get started with development is to use Visual Studio Code with devcontainers. This approach will create a preconfigured development environment with all the tools you need. This approach is enabled for all Home Assistant repositories.
Prerequisites
- git
- Docker
- For Linux, macOS, or Windows 10 Pro/Enterprise/Education use the current release version of Docker
- Windows 10 Home requires WSL 2 and the current Edge version of Docker Desktop (see instructions here). This can also be used for Windows Pro/Enterprise/Education.
- Visual Studio code
- Remote - Containers (VSC Extension)
More info about requirements and devcontainer in general
Getting started
- Fork the repository.
- Clone the repository to your computer.
- Open the repository using Visual Studio code.
When you open this repository with Visual Studio code you are asked to "Reopen in Container", this will start the build of the container.
If you don't see this notification, open the command palette and select Remote-Containers: Reopen Folder in Container
.
Tasks
The devcontainter comes with some useful tasks to help you with development, you can start these tasks by opening the command palette and select Tasks: Run Task
then select the task you want to run.
When a task is currently running (like Preview
for the docs), it can be restarted by opening the command palette and selecting Tasks: Restart Running Task
, then select the task you want to restart.
When using devcontainers and starting a preview via yarn start
, script/setup
or the Task in Code, a browser window will not be opened automatically, instead you will need to open a browser window to localhost:3000. If port 3000 was already in use, Docusaurus will use the next available port. You can check the port used in the terminal window of Visual Studio Code. Look for the line Project is running at http://0.0.0.0:XXXX/
where XXXX
3000 or greater, open a browser window to <http://localhost:XXXX>
.
Setting Up Your Own Environment
Running the documentation locally requires NodeJS and Yarn to be installed. Inside a cloned fork of this repository, run:
$ script/setup
Or in Windows, just run:
yarn
This will install docusaurus amongst other things.
Running docs locally
$ script/server
In Windows, just run
yarn start
It will start a server at localhost:3000.
Adding a page
- Create new page in
docs/
- Add new doc to
sidebars.js
