This tutorial is in Spanish. After two years between Costa Rica,Panama and Nicaragua,I suppose to be fluent,but I can't put two words together...
However,you can use an online translator to view it.
I found that Google translate works best for Latin American Spanish.
If something doesn't make sense from the translation,leave me a comment and I will ask my husband for help(he grew up in Costa Rica and is always happy to remind me that I should hit the books).
