+## Principles
+
+- active task is tracked automatically
+- progress through subdivision rather than guessing
+- TBI: show/hide closed/done tasks
+
+Recommendation: Flat hierarchy, using tags for filtering (TBI)
+
+## Reference
+
+TASK add syntax: `NAME: TAG1 TAG2`
+
+- `TASK` - create task
+- `.` - clear filters and reload
+- `.TASK` - filter / activate (by id or name) / create & activate task
+- `.NUM` - set view depth - how many subtask levels to show
+
+Dots can be repeated to move to parent tasks
+
+- `:[IND][COL]` - add / remove property column COL to IND or end
+- `>` - Complete active task and move to parent
+- `<` - Close active task and move to parent
+- TBI: `-TEXT` - add text note (comment / description)
+
+### Columns
+
+- `id`
+- `parentid`
+- `name`
+- `state`
+- `desc` - accumulated notes of the task
+- `path` - name including parent tasks
+- `rpath` - name including parent tasks up to active task
+- `time` - time tracked
+- `ttime` - time tracked including subtasks
+- TBI: `progress` - how many subtasks are complete
+
+For debugging: `props` - Task Property Events
+
 ## Plans
 
+- Expiry (no need to fetch potential years of history)
+- Web Interface, Messenger bots
 - TUI - Clear terminal?
