Hi @Fernanda1 thanks for reaching out! 
I invite you to take a look at our Translator’s Toolkit; there, you’ll find all the information you need to get started with us, including how to claim and submit tasks 
Also, taking our Introduction to Humanitarian Translation Course is a great way to start with us and learn more about TWB! It’s a self-paced course and you’ll receive a certificate once completed 
Thanks for your support, Fernanda! Do let us know if you have any questions
