+# Personal man page
+
+This repo is for my personal man page. It uses `pandoc` to process markdown into a manpage. See https://gabmus.org/posts/man_pages_with_markdown_and_pandoc
+
+1. create a markdown file for the manpage. We save it in section 7: _Miscellaneous Information Manual_, so it needs to be named `[name].7.md`.
+
+2. create a file in man page format using pandoc:
+   ```sh
+   pandoc --standalone -t man cheatsheet.7.md -o cheatsheet.7
+   ```
+3. Then symlink to the appropriate man file directory:
+
+   ```sh
+   ln -s /Users/hugh/coding/man/cheatsheet.7 /usr/local/share/man/man7/
+   ```
+Now you can run `man cheatsheet` and see your man page!
