Complete Build Guide

A comprehensive guide to building your product from your PRD.

❗Before You Start

This guide uses Claude Code (our recommended tool as of January 2026), but your PRD works with any AI coding tool. Make sure you have your coding tool installed and your PRD file ready.

Phase 1: Prepare Your Project

1

Create Project Directory

Create a new folder for your project and navigate into it:

bash
mkdir my-awesome-product
cd my-awesome-product
2

Add Your PRD

Save your PRD markdown file as PRD.md in the project folder.

Tip: You can find your PRD in the email we sent you, or download it from the chat interface.

3

Initialize Git (Optional)

Initialize version control to track changes:

bash
git init
git add PRD.md
git commit -m "Initial commit with PRD"

Phase 2: Start Building

4

Launch Claude Code

Start Claude Code in your project folder:

bash
claude

Claude Code will open an interactive session in your terminal.

5

Load Your PRD

Tell Claude to read and understand your PRD:

text
Read PRD.md and give me a summary of what we're building. Then start with Phase 1 of the implementation.
6

Review Phase Output

After each phase, Claude will show you what it built. Review the code and files created. Ask questions if anything looks wrong:

text
# Example questions you might ask:
"Why did you use this library instead of X?"
"Can you explain the authentication flow?"
"I need this to work differently - can you change..."
7

Proceed to Next Phase

When you're satisfied with the current phase, tell Claude to continue:

text
Looks good! Proceed to Phase 2.

Phase 3: Validate Each Phase

Your PRD includes validation checklists for each phase. Before moving to the next phase, ensure:

  • ✓All tests pass (if tests are included)
  • ✓The feature works as expected when you try it
  • ✓No critical errors in the console
  • ✓The build completes successfully
💡Run Validation Commands

Ask Claude to run the validation checklist for you:

text
Run all the validation commands for this phase and show me the results.

Common Issues

Finishing Up

Once all phases are complete, you should have a working product. Here are some next steps:

  1. Run a final build to ensure everything compiles
  2. Test all features manually
  3. Review the code for any security issues
  4. Deploy to your hosting platform
  5. Set up monitoring and error tracking
