const GETTING_STARTED = `Everything here is plain Markdown in this folder. No account, no sync, nothing leaves this computer.

A quiet place to write. Pages nest like folders, tags live in each file's front matter, and search runs against a local index.

## Write the way you think

- Type \`/\` on any line to add a heading, to-do, quote, toggle or code block.
- Start a line with \`#\`, \`-\`, \`[]\`, \`>\` or three backticks and it turns into that block as you type.
- Hover a block and drag the handle on its left to move it.
- Press <kbd>Ctrl</kbd> <kbd>K</kbd> to search every note or run a command.

## First steps

- [x] Pick a folder for your notes
- [ ] Write one page, however short
- [ ] Try the light theme from the switch in the sidebar

<details>
<summary>Where do my files actually live?</summary>

Each page is a \`.md\` file in this folder. A page with sub-pages gets a folder of the same name. The search index sits in \`.notes/index.sqlite\`; delete it any time and it rebuilds on launch.
