This pattern is suitable for an intermediate crocheter.
The download includes two patterns, one with UK and the other with US crochet terms.
The instructions are clear and have the stitch count for each row. There is a link to a video tutorial. There are also photo tutorials for some of the less basic stitches.
There is no gauge as such for this shawl, just adjust your hook size to get a fabric that you are happy with.
