 ## Usage
 
-To integrate Codecov with your Actions pipeline, specify the name of this repository with a tag number as a `step` within your `workflow.yml` file. This Action also requires you to provide an upload token from [codecov.io](https://www.codecov.io) (tip: in order to avoid exposing your token, store it as a `secret`). Optionally, you can choose to include three additional inputs to customize the upload context.
+To integrate Codecov with your Actions pipeline, specify the name of this repository with a tag number as a `step` within your `workflow.yml` file. This Action also requires you to [provide an upload token](https://docs.codecov.io/docs/frequently-asked-questions#section-where-is-the-repository-upload-token-found-) from [codecov.io](https://www.codecov.io) (tip: in order to avoid exposing your token, store it as a `secret`). Optionally, you can choose to include three additional inputs to customize the upload context.
 
 Inside your `.github/workflows/workflow.yml` file:
 
 ```yaml
 steps:
 - uses: actions/checkout@master
-- uses: actions/codecov-action@v1
+- uses: actions/codecov-action@v1.0.0
   with:
     token: ${{secrets.CODECOV_TOKEN}} #required
     file: ./coverage.xml #optional
     flags: unittests #optional
     name: codecov-umbrella #optional
 ```
->**Note**: This assumes that you've set your Codecov token inside *Settings > Secrets* as `CODECOV_TOKEN`. If not, you can get an upload token for your specific repo on [codecov.io](https://www.codecov.io).
