+# Releasing
+There are bash scripts found in the `/scripts` folder that details out the commands to publish the release files for the project.
+Primarily there is the `release.sh` script to publish the release builds, and the `macos.sh` to create the macOS packages. Both of these scripts are used in the 
+github release hook.
+
+## release.sh
+`/scripts/release.sh` will perform a `dotnet publish` to create a release binary for multiple platforms (`win-x64`, `osx-arm64`, `osx-x64`, `linux-arm64`, `linux-x64`)
+the releases are then placed into the `/build/` folder with each platform release under their own respective sub-directory. 
+
+## macos.sh
+`/scripts/macos.sh` is a separate script that is meant to be run after the release builds are generated from `/scripts/release.sh`. This script takes the generated release binaries and packages them into a `.app` for macOS
+The script itself takes in one of two arguments: `--x64` and `--arm64` to determine which macos package to generate. The output is then placed inside the `/build/` folder as `/build/osx_{platform}_macapp/TableauMigration.app`
