Hey, thank you very much for this! Much appreciated.

I'm wondering, does it need updating for every new release? Or did you automate it in some way?

If it isn't, maybe we can make it part of this repo so new releases get published automatically. Would you be up for creating a PR on this? It shouldn't be hard since goreleaser seems to support it already: https://goreleaser.com/customization/aur/

Then we can also add it to installation documentation.

At the moment I simply download the compiled release of v1.0.0 from the releases page. So each new release would require an updated PKGBUILD.
One could make a -git instead of a -bin package which actually compiles the project and always points to the latest commit.

GoReleaser sounds pretty exciting, didn't know it existed! I'd be happy to create a PR for a GitHub Actions workflow which publishes a new PKGBUILD for each release :-)
Is there already a SSH private key which can be referenced in the config file?
