+# Sonar's Electron dependency downloads itself via a post-install script.
+# When running in Sandcastle or devservers, the module install will fail
+# because we can't reach the internet. Setting the fwdproxy is dangerous, so
+# the next best thing is to install the modules with `--ignore-scripts`.
+# However, we can't run `install-node-modules.sh` like this all of the time.
+# `install-node-modules.sh` uses its args as keys for the "yarn watchman check"
+# cache. So if we run `install-node-modules.sh` outside of this script without
+# the flag, but then this script runs it with the flag, we're going to
+# invalidate the cache.
+
+# If `node_modules` exists, we can't tell if it was created with
+# `--ignore-scripts` or not, so we play it safe, and avoid touching it.
