### Installing the nightly release on an HarmonyOS device

The official nightly releases on [GitHub](https://github.com/servo/servo/releases) or [servo.org](https://servo.org/download/) are suitable for installation on OpenHarmony devices without additional steps. It is possible to install them on an HarmonyOS5 (or later) device, but the `hap` must self-signed first using the `hdc` tool.

but the hap must self-signed first using the hdc tool.

After the suggestions, this is incorrect now. hdc is just like adb, and only handles interaction with the device (e.g. in this case you use hdc to install the signed package).
We don't yet have steps for how to self-sign - I'd be fine with leaving how to do the self-sign undocumented right now (because I would still need to investigate what the best course here is).

I guess we just change the last line to:
It is possible to install them on an HarmonyOS5 (or later) device but the hap must be self-signed first.

Sure, but i agree with jonathan. We may need some docs how to self-sign. I'm trying it. :)
