                         PCBVAULT QUICK START GUIDE
========================================================================

Welcome to PCBVault. This manual outlines the core features and workflows
to help you get started with secure, offline-first PCB version management.

------------------------------------------------------------------------
1. SECURITY & ARCHITECTURE (OFFLINE-FIRST)
------------------------------------------------------------------------
* Zero-Knowledge Encryption: All project names, descriptions, file
  metadata, and raw engineering files are encrypted locally using AES-256.
* Local Storage: Your databases and files never leave your computer or
  your private network. They are stored in your user application directory
  or a configured local NAS folder.
* Master Password: Your master password derives your local encryption key.
  Keep it safe. If lost, your data cannot be recovered by anyone.

------------------------------------------------------------------------
2. GETTING STARTED
------------------------------------------------------------------------
* Account Creation: When you first launch PCBVault, you will create a
  local username and master password.
* Create a Vault: Click "Create New Vault" to choose a directory on your
  computer where PCBVault will store your encrypted databases and files.

------------------------------------------------------------------------
3. MANAGING PROJECTS & REVISIONS
------------------------------------------------------------------------
* Project Workspace: Drag and drop your project files (KiCad, Altium, etc.)
  directly into designated slots.
* Pessimistic Locking (Check-out/Check-in):
  - When you want to edit files, click "Check Out". This locks the files 
    for you, preventing other team members (on shared folders) from 
    making conflicting changes.
  - When you are finished, save your changes with revision notes, and 
    click "Check In" to release the lock and create a linear snapshot.
* Gerber & PDF Viewers: Use the built-in viewers to inspect layout files 
  and schematic PDFs directly inside the app.
* Digital Signatures: Finalized releases can be cryptographically signed
  by authorized engineers to verify design approval.

------------------------------------------------------------------------
4. LICENSE ACTIVATION
------------------------------------------------------------------------
To unlock unlimited projects or team features:
1. Copy the license key block provided to you in your email/checkout.
2. In the app, navigate to Settings -> License.
3. Paste the license key block into the Activation Input and click 
   "Activate".
4. The app will verify the cryptographic signature locally and activate 
   your plan.
