+### What is VAR_SELECT?
+
+It's a way to have translations on word or phrases that can change. To translate all the possibilities, you can follow this example done in Spanish:
+
+This
+
+```
+{VAR_SELECT, select, true {Close} false {Cancel} other {other} }
+```
+becomes
+
+```
+{VAR_SELECT, select, true {Cerrar} false {Cancelar} other {Otro} }
+```
+
+Basically just put the translation in the curly braces, for example `Close` in Spanish is `Cerrar`.
