The process is managed by a custom layer of node scripts and Electron-optimized configuration templates. Completed Installation packages are deployed to GitHub Releases. Builds for all platforms and architectures take about 5 minutes. Backed by the open-source-friendly guys at Travis and AppVeyor and running electron-packager under the hood.
