+# The script is based on tutorial written by Antonis Tsakiridis published at:
+# https://medium.com/@atsakiridis/continuous-deployment-for-ios-using-travis-ci-55dcea342d9
+#
+# It is intended to be executed through the Travis CI REST API call, as it
+# requires few arguments which are mandatory with no default values provided:
+# PR_REPO_SLUG - the Github name of the repo to be merged into the origin/master
+# PR_BRANCH - the branch to be merged, if set to "master" no merge will happen
+# IPA_DEPLOY_LOCATION - the location understandable by the "scp" command
+# executed at the end of the script to deploy the output .ipa file
+# LIB_JITSI_MEET_PKG (optional) - the npm package for lib-jitsi-meet which will
+# be put in place of the current version in the package.json file.
+#
+# Other than that the script requires the following env variables to be set
+# (reading the tutorial mentioned above will help in understanding the
+# variables):
+#
+# APPLE_CERT_URL - the URL pointing to Apple certificate (set to
+# http://developer.apple.com/certificationauthority/AppleWWDRCA.cer by default)
+# DEPLOY_SSH_CERT_URL - the SSH private key used by the 'scp' command to deploy
+# the .ipa. It is expected to be encrypted with the $ENCRYPTION_PASSWORD.
+# ENCRYPTION_PASSWORD - the password used to decrypt certificate/key files used
+# in the script.
+# IOS_DEV_CERT_KEY_URL - URL pointing to provisioning profile certificate key
+# file (development-key.p12.enc from the tutorial) encrypted with the
+# $ENCRYPTION_PASSWORD.
+# IOS_DEV_CERT_URL - URL pointing to provisioning profile certificate file
+# (development-cert.cer.enc from the tutorial) encrypted with the
+# $ENCRYPTION_PASSWORD.
+# IOS_DEV_PROV_PROFILE_URL - URL pointing to provisioning profile file
+# (profile-development-olympus.mobileprovision.enc from the tutorial) encrypted
+# with the $ENCRYPTION_PASSWORD.
+# IOS_SIGNING_CERT_PASSWORD - the password to the provisioning profile
+# certificate key (used to open development-key.p12 from the tutorial).
+# IOS_TEAM_ID - the team ID inserted into build-ipa-.plist.template file in
+# place of "YOUR_TEAM_ID".
