Thanks @JuanitoFatas , but I doubt this fix will last long, as this page's content is automatically re-generated from the relevant agent source code, which converts the forward ticks (in the agent source code) to backticks in the resulting Markdown/HTML of the docs.

We can't really change this to HTML tags in the agent source because these descriptions are used in the command line help options (i.e. buildkite-agent start --help), where these tags are likely to be rendered literally as is.

It might be worthwhile investigating if the relevant script that does this conversion for the docs can change the pairs of forward ticks to <code></code> tags in the resulting Markdown (for the HTML).

@gilesgas You’re right I fixed in the wrong place 🤦🏻‍♂️

No worries @JuanitoFatas , this can't be fixed until the relevant cli2md.rb script has been updated to handle forward ticks, which I also just discovered are called 'prime' symbols. Thanks again for caring!
