 ### Dotfile Management System
 The repository uses **symlink-based configuration deployment**. When `setup_env.sh` runs:
-1. Each dotfile in `dotfiles/` is backed up if it exists (to `.backup`)
-2. A symlink is created from `~/.<filename>` to the repository's `dotfiles/.<filename>`
-3. This allows version control of configs while keeping them in their expected locations
+1. `deploy_configs` symlinks each dotfile in `dotfiles/` to `~/.<filename>` (backing up any existing file)
+2. `deploy_bin` symlinks every file in `dotfiles/bin/` to `~/.local/bin/<filename>`
+3. This allows version control of configs and user-local scripts while keeping them in their expected locations

 - `td` - Find unchecked todo items using ripgrep
 - `tdp` - Find priority todos (with 🔼 or ⏫)

+- `tstart <tid>` - Start a timer on a task identified by a `^tid-*` block-ref
+- `tstop` - Stop the running timer
+- `treport [filter]` - Show totals per tid, filterable by tid or filename
+- Wrappers use `command td` to bypass the `td` rg alias. The CLI writes one row per entry to `$TD_LOG` (default `./time.csv`, cwd-scoped).
+- Companion nvim integration (in the separate `~/.config/nvim` repo) adds `<leader>ts/tp/tr` keymaps with auto-generated tids.
