+# sequin
+
+> Make ANSI escape sequences human-readable.
+> Useful for debugging, learning, or inspecting terminal output.
+> More information: <https://github.com/charmbracelet/sequin>.
+
+- Describe ANSI escape sequences from a string:
+
+`printf "{{Ciao, Baby.
+}}" | sequin`
+
+- Inspect colorized output from another command (e.g., `ls`):
+
+`ls -l --color=always | sequin`
+
+- Examine a file containing ANSI sequences (e.g., a TUI golden file):
+
+`cat {{path/to/file.golden}} | sequin`
+
+- Execute a command directly within a fake TTY to inspect its output:
+
+`sequin -- {{ls -l go.*}}`
+
+- Highlight raw ANSI sequences inline for easier reading:
+
+`git -c status.color=always status -sb | sequin -r`
