+# Obsidian
+
+Obsidian vault = a normal folder on disk.
+
+Vault structure (typical)
+- Notes: `*.md` (plain text Markdown; edit with any editor)
+- Config: `.obsidian/` (workspace + plugin settings; usually don’t touch from scripts)
+- Canvases: `*.canvas` (JSON)
+- Attachments: whatever folder you chose in Obsidian settings (images/PDFs/etc.)
+
+## Find the active vault(s)
+
+Obsidian desktop tracks vaults here (source of truth):
+- `~/Library/Application Support/obsidian/obsidian.json`
+
+`obsidian-cli` resolves vaults from that file; vault name is typically the **folder name** (path suffix).
+
+Fast “what vault is active / where are the notes?”
+- If you’ve already set a default: `obsidian-cli print-default --path-only`
+- Otherwise, read `~/Library/Application Support/obsidian/obsidian.json` and use the vault entry with `"open": true`.
+
+Notes
+- Multiple vaults common (iCloud vs `~/Documents`, work/personal, etc.). Don’t guess; read config.
+- Avoid writing hardcoded vault paths into scripts; prefer reading the config or using `print-default`.
+
+## obsidian-cli quick start
+
+Pick a default vault (once):
+- `obsidian-cli set-default "<vault-folder-name>"`
+- `obsidian-cli print-default` / `obsidian-cli print-default --path-only`
+
+Search
+- `obsidian-cli search "query"` (note names)
+- `obsidian-cli search-content "query"` (inside notes; shows snippets + lines)
+
+Create
+- `obsidian-cli create "Folder/New note" --content "..." --open`
+- Requires Obsidian URI handler (`obsidian://…`) working (Obsidian installed).
+- Avoid creating notes under “hidden” dot-folders (e.g. `.something/...`) via URI; Obsidian may refuse.
+
+Move/rename (safe refactor)
+- `obsidian-cli move "old/path/note" "new/path/note"`
+- Updates `[[wikilinks]]` and common Markdown links across the vault (this is the main win vs `mv`).
+
+Delete
+- `obsidian-cli delete "path/note"`
+
+Prefer direct edits when appropriate: open the `.md` file and change it; Obsidian will pick it up.
