All PlanetJune patterns are clearly written in English language, using standard (US) crochet terminology. To prevent confusion, every PlanetJune pattern includes a table of abbreviations used within the pattern that shows the standard stitch names and their equivalent stitch names in UK crochet terminology. For example, my sc (a single crochet in standard/US) is a double crochet stitch in UK/Aus terminology.
