How to add external training in chatterbot

I created a very simple bot to learn how to use chatterbot. This library already comes with a training, but I wanted to put an extra training with the import of a corpus in Portuguese that I found in github.

from chatterbot import ChatBot

bot = Futaba(
"Terminal",
storage_adapter="chatterbot.storage.SQLStorageAdapter",
logic_adapters=[
"chatterbot.logic.MathematicalEvaluation",
"chatterbot.logic.TimeLogicAdapter",
"chatterbot.logic.BestMatch"
],

input_adapter="chatterbot.input.TerminalAdapter",
output_adapter="chatterbot.output.TerminalAdapter",
database_uri="../database.db"
)

print("Type something to begin...")

while True:
    try:
        bot_input = bot.get_response(None)
    except (KeyboardInterrupt, EOFError, SystemExit):
        break

That's all I have.

How can I import this corpus into my chatbot?
