02 COLOR_MARKERS

Highlight important text with colour markers. All 4 markers are free for everyone:

Available markers

:danger: Red Critical warnings, destructive actions

:warn: Orange Cautions, potential issues

:tip: Green Best practices, recommendations

:info: Blue Additional information, notes

Usage example

## Git Undoing Changes

`git restore file` — Discard uncommitted changes
:warn: This permanently discards local changes

`git reset --hard HEAD~1` — Undo last commit
:danger: This deletes commit history—use with caution

`git stash` — Temporarily save changes
:tip: Use `git stash pop` to restore later

:info: Always create a branch before risky operations

Place the marker at the start of a line, followed by a space and your text.

04 QUICK_TIPS

Standard Markdown works. Headings (#, ##), lists (- or *), bold (**text**), code (`command`)—it all renders correctly.

Plan your columns. Most trifolds look best with 2-3 sections per column. Use  to control the split.

Use em dashes. Write command — description (em dash with spaces) rather than hyphens for cleaner output.

Target 400-500 words. This fills a trifold nicely. Too little looks sparse; too much overflows.

Preview before printing. The generator shows exactly how your PDF will look.
