+For example: `20260131-210000 Task Streamd.md`
 
 Within files, `@`-prefixed markers at the beginning of paragraphs or headings define how a shard is categorized.
 
 ## Commands
 
-- `streamer` / `streamer new` — Create a new timestamped markdown entry, opening your editor
-- `streamer todo` — Show all open tasks (shards with `@Task` markers)
-- `streamer edit [number]` — Edit a stream file by index (most recent first)
-- `streamer timesheet` — Generate time reports from `@Timesheet` markers
+- `streamd` / `streamd new` — Create a new timestamped markdown entry, opening your editor
+- `streamd todo` — Show all open tasks (shards with `@Task` markers)
+- `streamd edit [number]` — Edit a stream file by index (most recent first)
+- `streamd timesheet` — Generate time reports from `@Timesheet` markers
 
 ## Configuration
 
-Streamer reads its configuration from `~/.config/streamer/config.yaml` (XDG standard). The main setting is `base_folder`, which points to the directory containing your stream files (defaults to the current working directory).

 ## Usage
 
-Running `streamer` opens your editor to create a new entry. After saving, the file is renamed based on its timestamp and any markers found in the content.
