 | **Crawl with extra browser tweaks** | `crwl https://site.com -p my-profile -b "headless=true,viewport_width=1680"` | CLI overrides go on top of the profile. |
 | **Same but via explicit sub-command** | `crwl crawl https://site.com -p my-profile` | Identical to default alias. |
 | **Use profile from inside Profile Manager** | `crwl profiles` → choose **4** → pick profile → enter URL → follow prompts | Handy when demo-ing to non-CLI folks. |

 ## Output Formats
 
-- `all` - Full crawl result including metadata
-- `json` - Extracted structured data (when using extraction)
+- `all` - Full crawl result as formatted JSON, including HTML, markdown, and metadata (default)
+- `json` - Extracted structured data only (requires an extraction strategy)
 - `markdown` / `md` - Raw markdown output
 - `markdown-fit` / `md-fit` - Filtered markdown for better readability
 
+Use `-O <file>` to write the output to a file instead of the terminal.
+
+> **Note:** `-o json` prints only the extracted data, so it needs an extraction strategy (`-j` or `-e`, optionally with `-s`). Without one, the CLI exits with an error. Use `-o all` (the default) for the full crawl result as JSON.

 ## Complete Examples
 
-1. Basic Extraction:
+1. Full Crawl Result as JSON:
 ```bash
 crwl https://example.com \
     -B browser.yml \
     -C crawler.yml \
-    -o json
+    -o all \
+    -O result.json
 ```
 
 2. Structured Data Extraction:
