Admonitions and Callouts

GitHub-native alert syntax renders as semantic callouts.

[!NOTE] Useful information that readers should know, even when skimming.

[!TIP] Use callouts to highlight next steps, shortcuts, or recommended workflows.

[!IMPORTANT] Key information readers need before they continue.

[!WARNING] Urgent information that needs attention before taking action.

[!CAUTION] Risky choices or destructive actions should be called out clearly.

Task list
