Installation instructions are complete

Incomplete or missing installation instructions force every new developer to reverse-engineer the setup from source — inspecting package.json, searching for environment variables, and guessing at post-install steps. This breaks the adoption funnel at its first step. iso-25010:2011 analysability measures exactly this: the effort required to understand a system before using it. Vibe-coded projects frequently include generic boilerplate like a bare 'npm install' with no package name, no repository URL, and no mention of required setup steps that follow.

Add an Installation section with the exact command needed. If the package is published to a registry, name it. If it must be cloned, show both steps:

## Installation

```bash
npm install your-package-name

Or from source:

git clone https://github.com/org/repo.git
cd repo
npm install

Include any post-install steps (database migrations, `.env` setup, seed data) before the first run command. Instructions must reference the actual package name, not a placeholder.
