              As the name suggests, Octocat Classifier is used to determine whether a given image contains an Octocat. It is trained with images from the [Octodex](1), images shared with [#MyOctocat on Twitter](2), and [photographs of laptops with :octocat: stickers on them]().

              ## Installation

              ```
              git clone https://github.com/jasonetco/octocat-classifier
              ```
            
           ~/octocat-classifier gh repo create octocat-classifier
           Created repository jasonetco/octocat-classifier on GitHub
           Added remote https://github.com/jasonetco/octocat-classifier.git

           ~/octocat-classifier git push origin main

Find and fix vulnerabilities before you merge

Learn more about advanced security
  • Secure your code as you write it. CodeQL’s code scanning automatically reviews every change to your codebase and identifies known vulnerabilities before they ever reach production.

    Step 3
    Step 2
    Step 1
    Code injection alert
  • Keep your secrets. We automatically scan repositories for OAuth tokens, API keys, personal tokens, and more. If we find one, we’ll notify you and the partner that issued it to invalidate the secret.
