 ## Architecture
 
-- `index.ts` — CLI entry point, orchestration
+- `src/index.ts` — LMC CLI entry point, orchestration
+- `src/tts.ts` — TTSC CLI entry point (text-to-speech, Kokoro pipeline via `uv run`)
+- `src/config.ts` — `initConfig()`, `loadConfig()`: manages `~/.lmc_config.json`
+- `src/conversation.ts` — `Conversation` class: load/save to `~/.lmc_convo.json`
+- `src/errors.ts` — `handleTopLevel()`: TTY-aware error wrapping
+- `src/prompts.ts` — `commitDiff()`, `reviewFile()`, `reviewDiff()`, `file()`: prompt builders
 - `src/render/index.ts` — `Renderer` class: streams LLM response, buffers markdown, renders to stdout/stderr
-- `src/render/markdown.ts` — `renderMarkdown()`: syntax-highlighted markdown via `@comark/ansi` + Shiki
+- `src/render/markdown.ts` — `renderMarkdown()`: markdown via `marked` + Shiki + `@cliffy/table`
+- `src/render/codeToANSI.ts` — Shiki token output to ANSI escape sequences
 
 ## Gotchas
 
-- **Bun only** — not Node. Use `Bun.file()`, `Bun.argv`, `Bun.sleep()`.
+- **Node.js** — Use modern Node APIs (`node:fs/promises`, `node:stream/consumers`, etc.).
 - **No tests** — none exist.
-- **Biome config**: double quotes, space indent, auto-import-organize on. Run `bun run check` before committing.
+- **Biome config**: double quotes, space indent, auto-import-organize on. `pnpm run check` also runs `tsc --noEmit`.
+- **Build tools**: rolldown for ESM bundles, esbuild for CJS binaries, `node --build-sea` for SEA single-executable apps.
+- **TTS**: requires Python with `uv` — Kokoro pipeline lives in `tts/`.

-To install dependencies:
+A CLI tool for LLM chats with terminal native streaming.
+
+## Features
+
+- **Streaming markdown rendering** — incremental rendering with syntax highlighting
+- **Conversation persistence** — chat history saved to JSON
+- **Model configuration** — persist model preferences to JSON
+- **Reasoning display** — thinking tokens rendered _in style_ on stderr
+- **Usage stats** — input/output tokens and tokens/sec rate after each response
+- **TTY-aware** — automatically disables markdown rendering when output is piped
+- **Text-to-speech** — `ttsc` sub-command for streaming TTS via Kokoro model
+
+## Requirements
+
+- [pnpm](https://pnpm.io) v11+
+- [Node.js](https://nodejs.org) v22+
+- [uv](https://docs.astral.sh/uv/) — only for `ttsc` (text-to-speech)
+
+## Installation
 
 ```bash
-bun install
+# Bundle and install locally
+pnpm build
+pnpm add --global .
+
+# Build a single-file exe
+pnpm build:bin
+cp dist/lmc dist/ttsc /somewhere/bin/
+
+# For ttsc only
+cp -r tts ~/.ttsc
 ```
 
-To run:
+_Package to come later_
+
+## Usage
+
+### Chat (lmc)
 
 ```bash
-bun run index.ts
+lmc [options] <prompt...>
 ```
 
-This project was created using `bun init` in bun v1.3.11. [Bun](https://bun.com) is a fast all-in-one JavaScript runtime.
