If you run into trouble with GitHub rate limits, set the GITHUB_TOKEN environment variable like this:

jobs:
  tests:
    env:
      GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
    # etc...

Speed

If available, the fastest way to install is with the binary: tag (e.g. binary:1.4.0 or binary:stable). See nightlies.txt for a list of available versions.

Implementation

By default, this action uses choosenim to install Nim.

You can also explicitly request a particular build method by prefixing the version with a tag (e.g. git: as above). See .github/workflows/main.yml for examples.
