 - for systems where text can be copied to the clipboard at the same time as images, if `*ocr_ignore*` is copied with an image, the image will be ignored
 - optionally, notifications can be enabled in the config file to show the text with a native OS notification
 - optionally, you can speed up the online providers by installing fpng-py: `pip install fpng-py` (requires a developer environment on some operating systems/Python versions)
+- optionally, you can improve filtering of non-Japanese text for screen capture by installing transformers: `pip install transformers`
 - idle resource usage on macOS and Windows when reading from the clipboard has been eliminated using native OS polling
 - a config file (to be created in `user directory/.config/owocr_config.ini`, on Windows `user directory` is the `C:\Users\yourusername` folder) can be used to configure the script, as an example to limit providers (to reduce clutter/memory usage) as well as specifying provider settings such as api keys etc. A sample config file is provided [here](https://raw.githubusercontent.com/AuroraWright/owocr/master/owocr_config.ini)
