### Web services
[Helium services](https://github.com/imputnet/helium-services) are Helium's

the browser setup experience seen at `helium://setup` on first launch.

repo handles non-free assets used in Helium, such as search engine icons and
icons of other browsers.

[Helium Legal](https://github.com/imputnet/helium-legal) repo includes the
source for [Terms of Use](https://helium.computer/terms) and
[Privacy Policy](https://helium.computer/privacy) documents, along with their
full change history.

## Development
macOS and Linux are our primary development platforms, so they're the
recommended development environment for community contributions.

[> See development docs in macOS repo](https://github.com/imputnet/helium-macos/blob/main/docs/building.md#development-build-and-environment)

Linux packaging includes a similar development script, so the same guide
can be applied there too.
