How to use:

To use the extension. You must do the following: 1. Generate and Save a GitHub Token

  • Create a fine-grained personal access token on GitHub
  • Ensure Public repository access
  • Open Kuraji settings page
  • Paste generated token into text field, and click "Save Token" (This should be done because GitHub API rate limits unauthorized requests to 60/hr. Authorized increases that to 1000/hr. One single anime episode lookup could use 20+ requests.)

3. (Optional) Pair with a Japanese Popup Dictionary like Yomitan to assist in your language learning.
