+# Cross-platform Homebrew formula for SourceGit
+#
+# Note: This formula uses pre-built binaries because SourceGit requires .NET 10,
+# which is not yet available in Homebrew. Once Homebrew adds .NET 10 support,
+# this formula could be refactored to build from source and potentially
+# submitted to homebrew-core.
+#
+# For now, this formula is intended to be used via a third-party tap:
+#   brew tap sourcegit-scm/sourcegit
+#   brew install sourcegit
