 - If possible, use `nexusmods-app` for the package name.
 - We ship a build of `7zz` and use that executable unless you set `NEXUSMODS_APP_USE_SYSTEM_EXTRACTOR=1` when publishing. See [this issue](https://github.com/Nexus-Mods/NexusMods.App/issues/1306#issuecomment-2095755699) for details.
-- Set `INSTALLATION_METHOD_PACKAGE_MANAGER` when publishing. We have an integrated updater that will notify users about new versions. If you set this flag, we'll tell the user to update with their package manager.

+We publish the App using [PupNet](https://github.com/kuiperzone/PupNet-Deploy). Releases are built using GitHub Actions, see [`build-linux-pupnet.yaml`](https://github.com/Nexus-Mods/NexusMods.App/blob/main/.github/workflows/build-linux-pupnet.yaml) for details. PupNet will use `dotnet publish` before packaging the result in some specialized format.
+
+If you don't wish to use PupNet, you should still use `dotnet publish` over `dotnet build`. The arguments we use with `dotnet publish` can be found in [`app.pupnet.conf`](https://github.com/Nexus-Mods/NexusMods.App/blob/main/src/NexusMods.App/app.pupnet.conf). Also see the [`dotnet publish` documentation](https://learn.microsoft.com/en-us/dotnet/core/tools/dotnet-publish#options) for a list of options.
