 ## Features
 
 - **Config-driven startup**: Loads defaults from `config.yaml` with environment overrides.
-- **Interactive chat loop**: (In progress) command-driven conversation with persistent history.
-- **Extensible architecture**: Structured packages under `internal/` for config, app wiring, chat, storage, OpenAI client, UI, and telemetry.
+- **Interactive chat loop**: Command-driven conversation with OpenAI-compatible models.
+- **Persistent history**: Sessions and messages are stored in SQLite, allowing `/open` and `/rename` commands.
+- **Session naming assistance**: The assistant suggests descriptive session names that you can adopt.

+### Usage
+
+After launching, type messages at the prompt. The following commands are available:
+
+- `/help` – display available commands.
+- `/reset` – clear the current in-memory conversation.
+- `/list` – list saved sessions with summaries.
+- `/open <name>` – load a previously saved session by name.
+- `/rename <name>` – assign a new name to the current session (use suggestions or provide your own).
+- `/exit` – quit the application.
+
+The assistant proposes session name suggestions after the first reply in a session. Use `/rename <suggested-name>` to accept them quickly.
+
+### Persistence
+
+Goaichat uses SQLite for storage. On first run, the application applies migrations from `internal/storage/migrations/`. Sessions are automatically created when you begin chatting, and every message is stored for later retrieval.
+
+By default the database is stored at `$HOME/.local/share/goaichat/goaichat.db`. You can override the location via the `storage.path` or `storage.base_dir` settings in `config.yaml`.
