 # Anki Word Frequency
+
 Add word frequency to your Anki cards, powered by [wordfreq](https://github.com/rspeer/wordfreq).
 
 Frequency value is logarithmically scaled for readability, 
 defined [here](https://github.com/rspeer/wordfreq/blob/ce5307748723ddfb47eec26c3ece2eb8216c897a/README.md#usage).
 
 Supported languages listed [here](https://github.com/rspeer/wordfreq/blob/ce5307748723ddfb47eec26c3ece2eb8216c897a/README.md#sources-and-supported-languages).

 ## Usage
 1. Add a new field named "Frequency" (defined in config) to your card type.
 1. Select target cards in the browser, they should have a field named "Front" (also configurable).
 1. Right click and choose your language under "Word Frequency" tab to update the frequency field.

 ## Known Issues
 - Tested on Windows, should support most variants of Linux and MacOS.
 - Some custom tokenizers in the dependencies write logs to *stderr* (e.g. `jieba`), this will get displayed in a error popup window in Anki, but can be safely ignored.
