+# PRD 0054: Install script
+
+- **Status:** Draft
+- **Author:** didericis
+- **Created:** 2026-06-06
+- **Issue:** #197
+
+## Summary
+
+Add a proper Python package distribution and a thin `install.sh` bootstrapper so users can install bot-bottle with a single command without cloning the repo.
+
+## Problem
+
+There is currently no install path for new users. The only way to run bot-bottle is to clone the repo and invoke `cli.py` directly. This blocks any HN-style public demo: readers want `curl | sh` or `pipx install`, not a manual clone-and-configure flow.
+
+## Goals / Success Criteria
+
+- `curl -fsSL <url>/install.sh | sh` (or equivalent) leaves a working `bot-bottle` command on PATH.
+- Python-native users can install with `pipx install bot-bottle` or `uv tool install bot-bottle`.
+- `install.sh` validates prerequisites (Python ≥ 3.11, Docker) and exits with a clear message if they are missing. It does not silently install Docker.
+- `install.sh` runs `bot-bottle doctor` (or equivalent diagnostic) after install to confirm the environment is ready.
+- The package has no runtime pip dependencies (stdlib-only, matching the existing constraint).
+
+## Non-goals
+
+- Bundling a Python runtime or producing a standalone binary.
+- Automatic Docker installation.
+- Plugin architecture changes (out of scope; see issue #197 for future direction).
+- Publishing to PyPI in this PR — the package structure is the deliverable; publishing is a separate step.
+
+## Design
+
+### Package structure
+
+Add a minimal `pyproject.toml` at the repo root:
+
+```toml
+[project]
+name = "bot-bottle"
+version = "0.1.0"
+requires-python = ">=3.11"
+dependencies = []
+
+[project.scripts]
+bot-bottle = "bot_bottle.cli:main"
+```
+
+The existing `bot_bottle/` package and `cli.py` entry point already contain the logic; this just wires up the standard entry point. `cli.py` may need a small refactor to expose a `main()` callable if it uses `if __name__ == "__main__"` only.
+
+### `install.sh`
+
+A thin bootstrapper that:
+
+1. Checks `python3 --version` ≥ 3.11; exits with instructions if not met.
+2. Checks `docker info` exits 0; exits with instructions if Docker is not running.
+3. Installs via `pipx` if available, otherwise falls back to `pip install --user`.
+4. Runs `bot-bottle doctor` to verify the install.
+
+The script must be idempotent (safe to re-run) and must not require `sudo`.
+
+### `bot-bottle doctor`
+
+A new subcommand that checks and reports:
+
+- Python version.
+- Docker daemon reachability.
+- Whether `~/.bot-bottle/` config directory exists.
+
+Exits 0 if all checks pass, non-zero otherwise.
+
+## Open questions
+
+- Where should `install.sh` be hosted for the `curl | sh` path? (Options: raw Gitea, a separate static host, GitHub releases if/when the repo is mirrored.) Resolve before shipping.
+- Should `version` in `pyproject.toml` be driven by a git tag at build time (e.g. via `hatch-vcs`) or kept as a static string? Static is simpler for now.
