Obsidian is two things:

1. **A folder of plain markdown files on your hard drive** — yours, portable, editable in any text editor.
2. **A friendly editor that links those files together** with backlinks, graph view, and plugins.

That's it. There's no proprietary database. No cloud account required. No vendor lock-in. If Obsidian disappeared tomorrow, your notes would still open in VS Code, Notepad, or any text editor.

## Your specific setup

Your vault lives at:

```
C:\Vault\WhittechAI
```

Open File Explorer and navigate there. You'll see folders like `00-Inbox`, `10-Daily`, `20-Projects`. Each one contains `.md` files — plain text with light formatting. Open any of them in Notepad. You'll see:

```markdown
# Today's note

- [ ] Pick up dry cleaning
- [x] Send the proposal

Some thoughts...
```

That's a complete Obsidian note. The hash makes a heading. The bullet-dash-square-bracket makes a task. The rest is prose. No magic.

## Why this matters

Because your notes will outlive any single app. Your vault works:

- **Without internet** — it's all local
- **Without Obsidian** — open the `.md` files in anything
- **Across decades** — markdown predates Obsidian by 20 years and isn't going anywhere
- **Without paying** — Obsidian is free for personal use

Compare to Notion, Roam, Evernote — all proprietary databases. Export and you get a different file format than what you put in. With Obsidian, what you write is what you get.

## The vault as a folder

Your vault is **just a folder**. That has consequences:

- Want to back it up? Copy the folder.
- Want to sync with your phone? Use any file sync tool (you picked Syncthing).
- Want to version it? `git init` inside the folder.
- Want to grep it? `rg "search term" C:\Vault\WhittechAI` works fine.
- Want to programmatically edit it? Any tool that writes text files works — including Claude Code via the Obsidian MCP.

This is why the workflows on this site work. Claude isn't talking to a special API. It's reading and writing `.md` files in a folder, and Obsidian sees the changes instantly.

## What's in a vault

Looking at your `C:\Vault\WhittechAI` right now:

```
00-Inbox/          Stuff to triage
10-Daily/          One note per day
20-Projects/       Active work
30-Areas/          Ongoing responsibilities
40-Resources/      Reference material
50-Archive/        Done / dead
60-People/         Personal CRM
70-Meetings/       Meeting notes
80-Content/        Drafts + published
90-Templates/      Note skeletons
_setup/            How this stack works
```

That's a vault. Numbered folders so they sort alphabetically. PARA-ish, with extras.
