Exporting and adding members to channels requires the user from which the script is launched to be a Channel admin.

You'd need python3 and pip3 installed and available in your PATH.

Run pip3 install -r requirements.txt from the projects root directory.

1. To run it you need to generate API credentials for your Telegram user, you can do it here, and access your already created ones here
2. Replace your credentials in the script

   api_id = 000000        # YOUR API_ID
   api_hash = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'        # YOUR API_HASH
   phone = '+34000000000'        # YOUR PHONE NUMBER, INCLUDING COUNTRY CODE

Just follow the instructions in the script after running it from your the shell.

Users can be added using:

• Username: Gets temporarily banned with less requests.
• User ID: Gets temporarily banned with more requests.

Temporarily bans last for up to a day in my experience.

Adding users by Username expects a CSV file with one username per line. Adding users by User ID expects a CSV file such as: username,user_id,user_access_hash

No headers are expected in the CSV files

Once you have your CSV prepared, just follow the instructions in the script.
