Thanks for submitting your kubectl plugin to Krew!
One of the krew-index maintainers will review it soon. Note that the reviews for new plugin submissions may take a few days.

In the meanwhile, here are a few tips to make your plugin manifest better:

• Make sure your plugin follows the best practices.
• Eliminate redundant wording form shortDescription (it should be max 50 characters).
• Try to word wrap your description to 80-character lines (no usage examples, please).

Thanks for your patience!
