 # 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.
