How to open a .md file

An .md is a text file. You can open it two ways — one instant, one more convenient for building your library.

Way 1 — as an ordinary text file (right away, nothing to install)

• Windows: right-click the file → Open with → Notepad. (Or rename the extension from .md to .txt and double-click.)
• Mac: open it with TextEdit.
• Anywhere: drag the file into a text editor, or even into a browser window.

You'll see the content with the Markdown marks (#, -, **): it's all there, readable.

Way 2 — with Obsidian (to read it formatted and keep it in a library)

Obsidian is a free app that reads folders of .md files, shows them formatted (headings, lists, bold rendered nicely) and lets you link them to each other.

1. Download Obsidian from obsidian.md and install it.
2. Create (or open) a vault: it's simply a folder on your computer.
3. Put the downloaded .md file inside that folder.
4. Open it in Obsidian: you see it formatted, and you can search it, annotate it, link it to your other skills.

That's how you build your library of skills and prompts, locally, all searchable.

Note

If you downloaded the .txt version, it opens exactly the same way (it's text): Notepad/TextEdit works fine; Obsidian, on the other hand, prefers .md files.
