 **To Reproduce**
 
-1. Provide copyable *text* (not an image) that reproduces the issue.
-2. Provide a `chroma` command-line invocation to reproduce the issue with the above input text. eg. for Hugo the (rough) equivalent would be `chroma -s monokailight --html --html-lines --html-lines-table --html-inline-styles <source>`
+Either:
+
+1. Reproduce your issue in the [Chroma Playground](https://swapoff.org/chroma/playground/), then click the _copy_ icon to copy a shareable link for your issue. Consider using `[markdown links](URL)` to minimise the visual noise of the links.
+2. Provide input text and a command-line invocation of `chroma` that reproduces your problem. eg. For Hugo this might be something like `chroma -s monokailight --html --html-lines --html-lines-table --html-inline-styles <source>`
