 Platform translation strings are stored as JSON in the [core](https://github.com/home-assistant/core) repository. These files must be located adjacent to the component/platform they belong to. Components must have their own directory, and the file is simply named `strings.json` in that directory. This file will contain the different strings that will be translatable.

 Unlike localized strings merged in the `home-assistant` repository, custom integrations cannot take advantage of Lokalise for user-submitted translations. However, custom integration authors can still include translations with their integrations. These will be read from the `translations` directory, adjacent to the integration source. They are named `<language_code>.json` in the `translations` directory, e.g., for the German translation `de.json`.

 The main repository located at [github.com/home-assistant/operating-system/](https://github.com/home-assistant/operating-system/) contains Buildroot customizations via the [br2-external mechanism](https://buildroot.org/downloads/manual/manual.html#outside-br-custom) as well as helper scripts and GitHub Action CI scripts. The main repository uses the Git Submodule mechanism to point to Buildroot itself. While most customizations can be done by the br2-mechanism, some modifications are made to Buildroot itself. For that reason we also maintain a fork of Buildroot under [github.com/home-assistant/buildroot/](https://github.com/home-assistant/buildroot/). The aim is to keep the amount of patches on-top of upstream Buildroot minimal.

 Home Assistant Operating System uses [RAUC](https://rauc.io/) as the update system. RAUC is an image based update system designed for embedded systems. It has support for multiple boot slots thus supporting A/B style update mechanism. The update system integrates with popular bootloaders such as U-Boot but also allows integration with custom boot flows via scripts. It uses X.509 cryptography to sign and verify update bundles.
