Local Dev Environment Setup Guide

What a good one includes

• A clear list of system prerequisites, including specific language runtime versions and global package managers required before cloning.
• Copy-and-paste terminal commands for cloning the repository, installing local dependencies, and spinning up necessary background services.
• A dedicated environment variable configuration section detailing how to copy the template file and where to securely acquire development API keys.
• Step-by-step instructions for initializing, migrating, and seeding the local database with dummy data for testing.
• The exact commands to start the local development server and verify it is running via a specific local port or localhost URL.
• A troubleshooting section addressing common failure points like port conflicts, permission errors, and operating system quirks.

Common mistakes to avoid

• Assuming pre-existing global dependencies like Docker, Homebrew, or specific database clients are already installed without listing them in the prerequisites.
• Hardcoding sensitive credentials, API keys, or personal paths directly in the guide instead of referencing a secure environment variable template.
• Allowing the documentation to rot by failing to update setup steps when upgrading major framework versions or changing system dependencies.
• Ignoring operating system differences, leaving Windows or macOS users stuck on bash-specific commands that do not run on their native terminals.
