+# WHAT DO YOU NEED TO USE THIS SCRIPT?
+#
+# 1. Install gcloud locally on the computer: https://cloud.google.com/sdk/docs/install-sdk
+#    - Make sure to use these two commands at the end to use it properl (replacing path_to_the_google-cloud-sdk with the actual path to the folder where gcloud is intalled):
+#      source 'path_to_the_google-cloud-sdk/path.zsh.inc'
+#      source 'path_to_the_google-cloud-sdk/completion.zsh.inc'
+# 2. The JSON file stored in 1Password under "Google service account credentials — mbd-translation-service"
+# 3. Authenticate the service account using the JSON file (replace path_to_json_file with the path to the file):
+#      gcloud auth activate-service-account --key-file=path_to_json_file/mbd-translation-service-894707d1513b.json
+# 4. Delete the JSON file once you are authenticated.
+
+
+# HOW TO USE THIS SCRIPT
+#
+# 1. Once the "mbd-translation-service@mbd-translation-service.iam.gserviceaccount.com" service account is authenticated, you can use this script.
+# 2. Optionally, check if the correct account is logged in with this command : gcloud auth list. You should see this:
+#      mbd-translation-service@mbd-translation-service.iam.gserviceaccount.com
+# 3. In terminal, cd into the directory where this script is located, presumably the gtfs.org repo, then inside the scripts folder.
+# 4. The script assumes the source language is always english, and will translate in all the other languages it knows.
+# 5. You need to search and replace backticks (`) for \` to escape them otherwise they will interfere with the command by closing the argument too soon.
+#    - Use a simple text editor like TextEdit for this.
+# 4. Call the command like this:
+#      ./google-api-translator.sh "This is some text to translate."
+# 5. Copy and paste the results into a text editor and use the script to clean it up of the usual mistakes.
+#    - Inspect the translations for any other errors that might have been introduced and is not fixed by the script mentioned above.
+# 6. When pasting in the final file, confirm visually that the markdown is not broken. Always refer to the English version as a reference.
+
+
+# HOW TO UPDATE THE GLOSSARIES
+#
+# 1. Edit the .csv files for each of the language(s) you wish to add an entry to
+#    - For "do not translate" entries, you need to add the same entries to all the files.
+# 2. Commit and do a PR, have it reviewed and approved.
+# 3. Merge into "main" on the repo.
+# 4. A GitHub action will start the process of updating the glossaries. Allow up to 30 minutes for this to complete before using this script.
+
+
+# Array of target languages
+target_languages=("fr" "es" "ru" "ja" "id" "de" "pt_BR" "ko" "zh" "zh_TW")
+
+# Prefix for the name of a glossary
+glossary_name_prefix="mobilitydata-glossary-en-to-"
+
+# Argument provided to the script
+input_string="$1"
+
+# Replace apostrophes with '"'"'
+processed_string=$(echo "$input_string" | sed "s/'/'\"'\"'/g")
