+# WARNING: TRY TO KEEP THIS FILE AS LEAN AS POSSIBLE
+# The rules:
+# - think twice before adding installer that takes long time (builds are already slow)
+# - do not add any steps that are flaky (builds will become flaky)
+# - try adding a dependency under a language-specific section first (reduces latency and increases build stability)
+# - only add stuff that you absolutely need for your builds to work (add comment to explain why its needed)
