+# =============================================================

+# Purpose:
+# --------
+# This script configures Configure iOS simulators and Android emulators to connect to
+# new.expensify.com.dev over https for local development.
+#
+# Background:
+# -----------
+# We plan to change the URL to serve the App on the development environment from
+# localhost:8082 to new.expensify.com.dev. This can be accomplished by adding a new entry
+# to the laptop's hosts file along with changes made in the PR.
+# However, we're not sure how we can access the App on Safari or Chrome on iOS or Android
+# simulators.
+#
+# How this script helps:
+# ----------------------
+# This script streamlines the process of adding the certificates to both android and
+# ios platforms.
+#
+# Usage:
+# ------
+# To run this script, pass the platform on which you want to run as a command-line
+# argument which can be the following:
+# 1. ios
+# 2. android
+# 3. all (default)
