[Cin] Translate CinelerraGG in spanish

I'm Spanish and I've been trying Cinelerra GG for a few days and I liked it so much that I decided to write a series of tutorials about the application. I have noticed many errors and misspellings in the Spanish translation, how can I help to correct and improve the translation? I am an audiovisual technician and my programming knowledge is very low. If you tell me the steps to follow I can help.
