+
+Create an API token at [hackmd.io/settings#api](https://hackmd.io/settings#api), then configure:

+```bash
+# Interactive login (saves to ~/.hackmd/config.json)
+hackmd-cli login
+
+# Or via environment variable
+export HMD_API_ACCESS_TOKEN=YOUR_TOKEN
+```
+
+For HackMD EE instances, also set the API endpoint:
+
+```bash
+export HMD_API_ENDPOINT_URL=https://your.hackmd-ee.endpoint
+```
+
+## Commands
+
+### Authentication
+
+```bash
+hackmd-cli login              # Set access token interactively
+hackmd-cli logout             # Clear stored credentials
+hackmd-cli whoami             # Show current user info
+```
+
+### Personal Notes

+hackmd-cli notes --noteId=<id>
+
+# Create note
+hackmd-cli notes create --content='# Title' --title='My Note'
+hackmd-cli notes create --readPermission=owner --writePermission=owner
+
+# Create from file/stdin
+cat README.md | hackmd-cli notes create
+
+# Create with editor
+hackmd-cli notes create -e
+
+# Update note
+hackmd-cli notes update --noteId=<id> --content='# New Content'
+
+# Delete note
+hackmd-cli notes delete --noteId=<id>
+```
+
+### Team Notes
+
+```bash
+# List team notes
+hackmd-cli team-notes --teamPath=<team-path>
+
+# Create team note
+hackmd-cli team-notes create --teamPath=<team-path> --content='# Team Doc'
+
+# Update team note
+hackmd-cli team-notes update --teamPath=<team-path> --noteId=<id> --content='# Updated'
+
+# Delete team note
+hackmd-cli team-notes delete --teamPath=<team-path> --noteId=<id>
+```
+
+### Teams & History
+
+```bash
+hackmd-cli teams              # List accessible teams
+hackmd-cli history            # List browsing history
+```
+
+### Export
+
+```bash
+hackmd-cli export --noteId=<id>    # Export note content to stdout
+```
+
+## Permissions
+
+Available permission values:
+
+| Permission Type | Values |

+--output=yaml        # YAML output
+--output=csv         # CSV output (or --csv)
+--no-header          # Hide table headers
+--no-truncate        # Don't truncate long values
+--columns=id,title   # Show specific columns
+--filter=name=foo    # Filter by property
+--sort=title         # Sort by property (prepend '-' for descending)
+-x, --extended       # Show additional columns
+```
+
+## Common Workflows
+
+### Sync local file to HackMD
+
+```bash
+# Create new note from file
+cat doc.md | hackmd-cli notes create --title="My Doc"
+
+# Update existing note from file
+cat doc.md | hackmd-cli notes update --noteId=<id>
+```
+
+### Export note to local file
+
+```bash
+hackmd-cli export --noteId=<id> > note.md
+```
+
+### List notes as JSON for scripting
+
+```bash
+hackmd-cli notes --output=json | jq '.[] | .id'
+```
+
+### Find note by title
+
