 The following tokens are suitable for uploading:
 
-* The [Repository Upload Token](https://docs.codecov.com/docs/codecov-uploader#upload-token): Found on the settings page of your repository, also viewable on the `/new` page when setting up a repository on Codecov for the first time. 
-* The [Global Upload Token](https://docs.codecov.com/docs/codecov-uploader#organization-upload-token): Found on your organization settings page (e.g., `https://app.codecov.io/account/<scm>/<org>/org-upload-token`).

 # How to Use Local Upload
 
-The CLI also supports "dry run" local uploading. This is useful if you prefer to see Codecov status checks and coverage reporting locally, in your terminal, as opposed to opening a PR and waiting for your full CI to run. Local uploads do not interfere with regular uploads made from your CI for any given commit / Pull Request.

 ## Static Analysis
 
-The CLI can perform basic static analysis on Python code today. This static analysis is meant to power more future looking Codecov features and, as such, is not required or in active use today. As more functionality dependent on static analysis becomes available for use, we will document static analysis in detail here.
