-## Instructions
+## Instrucciones
 
-Now that you have built an ARIMA model, build a new one with fresh data (try one of [these datasets from Duke](http://www2.stat.duke.edu/~mw/ts_data_sets.html). Annotate your work in a notebook, visualize the data and your model, and test its accuracy using MAPE.
