Welcome to Your Curriculum Command Center

This guide will turn you into a Wiki2web Studio power user. Let's unlock the features designed to give you back your weekends.

The Core Concept: What is a "Kit"?

Think of a Kit as your all-in-one digital lesson plan. It's a single, portable file that contains every piece of content for a topic: your subject categories, a central image, all your flashcards, and all your questions. The true power of the Studio is speed—once a kit is made (or you import one), you are just minutes away from printing an entire set of coursework.

Getting Started is Simple:

  • Create New Kit: Start with a clean slate. Perfect for a brand-new lesson idea.
  • Import & Edit Existing Kit: Load a .json kit file from your computer to continue your work or to modify a kit created by a colleague.
  • Restore Session: The Studio automatically saves your progress in your browser. If you get interrupted, you can restore your unsaved work with one click.

Step 1: Laying the Foundation (The Authoring Tools)

This is where you build the core knowledge of your Kit. Use the left-side navigation panel to switch between these powerful authoring modules.

⚙️ Kit Manager: Your Kit's Identity

This is the high-level control panel for your project.

  • Kit Name: Give your Kit a clear title. This will appear on all your printed materials.
  • Master Image: Upload a custom cover image for your Kit. This is essential for giving your content a professional visual identity, and it's used as the main graphic when you export your Kit as an interactive game.
  • Topics: Create the structure for your lesson. Add topics like "Chapter 1," "Vocabulary," or "Key Formulas." All flashcards and questions will be organized under these topics.

🃏 Flashcard Author: Building the Knowledge Blocks

Flashcards are the fundamental concepts of your Kit. Create them here to define terms, list facts, or pose simple questions.

  • Click "➕ Add New Flashcard" to open the editor.
  • Fill in the term/question and the definition/answer.
  • Assign the flashcard to one of your pre-defined topics.
  • To edit or remove a flashcard, simply use the ✏️ (Edit) or ❌ (Delete) icons next to any entry in the list.

✍️ Question Author: Assessing Understanding

Create a bank of questions to test knowledge. These questions are the engine for your worksheets and exams.

  • Click "➕ Add New Question".
  • Choose a Type: True/False for quick checks or Multiple Choice for more complex assessments.
  • To edit an existing question, click the ✏️ icon. You can change the question text, options, correct answer, and explanation at any time.
  • The Explanation field is a powerful tool: the text you enter here will automatically appear on the teacher's answer key and on the Smart Study Guide, providing instant feedback.

🔗 Intelligent Mapper: The Smart Connection

This is the secret sauce of the Studio. The Mapper transforms your content from a simple list into an interconnected web of knowledge, automating the creation of amazing study guides.

  • Step 1: Select a question from the list on the left.
  • Step 2: In the right panel, click on every flashcard that contains a concept required to answer that question. They will turn green, indicating a successful link.
  • The Payoff: When you generate a Smart Study Guide, these linked flashcards will automatically appear under each question as "Related Concepts."

Step 2: The Magic (The Generator Suite)

You've built your content. Now, with a few clicks, turn it into a full suite of professional, ready-to-use materials. What used to take hours of formatting and copying-and-pasting can now be done in seconds.

🎓 Smart Study Guide Maker

Instantly create the ultimate review document. It combines your questions, the correct answers, your detailed explanations, and all the "Related Concepts" you linked in the Mapper into one cohesive, printable guide.

📝 Worksheet & 📄 Exam Builder

Generate unique assessments every time. The questions and multiple-choice options are randomized automatically. Simply select your topics, choose how many questions you need, and generate:

  • A Student Version, clean and ready for quizzing.
  • A Teacher Version, complete with a detailed answer key and the explanations you wrote.

🖨️ Flashcard Printer

Forget wrestling with table layouts in a word processor. Select a topic, choose a cards-per-page layout, and instantly generate perfectly formatted, print-ready flashcard sheets.

Step 3: Saving and Collaborating

  • 💾 Export & Save Kit: This is your primary save function. It downloads the entire Kit (content, images, and all) to your computer as a single .json file. Use this to create permanent backups and share your work with others.
  • ➕ Import & Merge Kit: Combine your work. You can merge a colleague's Kit into your own or combine two of your lessons into a larger review Kit.

You're now ready to reclaim your time.

You're not just a teacher; you're a curriculum designer, and this is your Studio.
