 Options:
 
-- `targetFormat` - the format to output, can be either `'truetype'`, `'woff'`, or `'woff2'`.
+- `targetFormat` - the format to output, can be either `'sfnt'`, `'woff'`, or `'woff2'`.

+For backwards compatibility reasons, `'truetype'` is supported as an alias for `'sfnt'`.
 
 ## Why not use harfbuzzjs directly?
 
 This middle-man module only really exists for convenience.
 
 - `harfbuzzjs` is deliberately low-level bindings for HarfBuzz. While very flexible, it means that you need a series of hard-to-get-right incantations to move data in and out of the WebAssembly heap and carry out a subsetting operation. See [harfbuzz/harfbuzzjs#9](https://github.com/harfbuzz/harfbuzzjs/issues/9).
-- The subsetting routines in HarfBuzz only support the Truetype format. `subset-font` adds support for reading and writing WOFF and WOFF2 via the [`fontverter`](https://github.com/papandreou/fontverter) library.
