   * By default we have set the `threshold` to 0.01, you can increase that value by passing a customDiffConfig as demonstrated below.
   * Please note the `threshold` set in the `customDiffConfig` is the per pixel sensitivity threshold. For example with a source pixel colour of `#ffffff` (white) and a comparison pixel colour of `#fcfcfc` (really light grey) if you set the threshold to 0 then it would trigger a failure *on that pixel*. However if you were to use say 0.5 then it wouldn't, the colour difference would need to be much more extreme to trigger a failure on that pixel, say `#000000` (black)

 ## How it works
-  Given an image (should be either a PNGImage instance or a Buffer instance with PNG data) the `toMatchImageSnapshot()` matcher will create a `__image_snapshots__` directory in the directory the test is in and will store the baseline snapshot image there on the first run.
+  Given an image (should be either a PNGImage instance or a Buffer instance with PNG data) the `toMatchImageSnapshot()` matcher will create a `__image_snapshots__` directory in the directory the test is in and will store the baseline snapshot image there on the first run. Note that if `customSnapshotsDir` option is given then it will store baseline snapshot there instead.
 
   On subsequent test runs the matcher will compare the image being passed against the stored snapshot.
