 # Preparation
 
-TODO
+This module is entirely practical. You will work in a team and go through real development processes: discussing a product, defining an MVP, running sprint planning, daily standups, writing code, doing reviews, and completing a retrospective.
+To participate effectively, you must review key concepts from the Foundation module and study several additional topics that we will actively use during the session.
+
+## Part 1. Review key topics from [the Foundation module](../../../courses/foundation/intro-to-agile/week1/preparation.md)
+
+Before the session, make sure you remember the following concepts:
+
+- Agile Manifesto and core Agile values
+- Differences between Waterfall and Agile
+- Scrum framework: roles, events, artifacts
+- What a Sprint is and what an Increment means
+- How Product Backlog and Sprint Backlog work
+
+## Part 2. Key concepts to study in more depth
+
+### MVP (Minimum Viable Product)
+
+#### What you need to know
+
+- MVP is the smallest version of a product that delivers real value to the user.
+- It is not a “cut-down” product. It is the fastest path to testing a hypothesis.
+- MVP does not need full polish, but it must work and allow learning through feedback.
+
+![Making sense of MVP](session-materials/Making-sense-of-MVP.jpg)
+
+> **Simple example**
+>
+> Imagine building a recipe web app.
+>
+> A full version might include:
+>
+> - advanced search
+> - shopping lists
+> - user profiles
+> - photos + video instructions
+> - comments
+> - recommendations
+> - nutrition data
+>
+> But an MVP could be:
+>
+> - a list of recipes,
+> - step-by-step instructions,
+> - one image per recipe.
+>
+> A user can already cook a dish.
+> Value is delivered — the product is validated.
+
+### Sprint & Planning
+
+#### Sprint
+
+A short, fixed period (usually 1–2 weeks) where the team focuses on delivering a specific, working increment of the product.
+
+#### Sprint Goal
+
+A clear answer to:
+What valuable outcome do we want to deliver by the end of this sprint?
+
+> Example:
+>
+> "The user should be able to add tasks to a list."
+
+#### Sprint Planning
+
+Planning consists of three core parts:
+
+1. Define the Sprint Goal.
+2. Select the tasks that support that goal.
+3. Estimate and confirm what the team can realistically complete.
+
+#### Important
+
+Sprint Planning is collaborative.
+Tasks are not assigned top-down — the team decides how to achieve the Sprint Goal.
+
+### Code Review
+
+#### Why it matters
+
+- Improves code quality
+- Reduces bugs
+- Shares knowledge within the team
+- Creates consistent standards
+
+#### What makes a good Pull Request
+
+- Small — easy to read and review
+- Atomic — solves one task, not many at once
+- Clear — understandable naming and structure
+
+#### Common pitfalls
+
+- Huge PRs that are difficult to review
+- Missing or unclear descriptions
+- Unrelated changes mixed together
+- Ignoring review comments or resolving them without applying the changes
+
+#### Your responsibility
+
+Even as a junior developer, you must be able to:
+
+- open PRs,
+- request reviews,
+- give constructive comments,
+- update code based on feedback.
+
+> **Example**
+>
+> A developer decides to introduce a new third-party library to improve a component.
+> During review, teammates raise concerns:
+>
+> - the library is incompatible with the existing build setup,
+> - it significantly increases bundle size,
+> - it will require refactoring shared components.
+>
+> The developer ignores the comments and merges the PR.
+>
+> What happens next:
+>
+> - The project stops building for the entire team.
+> - CI pipeline fails on every branch.
+> - Developers spend hours reverting and repairing the codebase.
+> - The sprint plan collapses.
+> - Trust in the process drops.
+> - Overall team productivity declines.
+>
+> Conclusion:
+> Code review is not a formality. It protects the team, the product, and the development flow.
+
+## Key idea
+
+This module simulates real teamwork in a real development cycle.
+Preparation is needed so we spend the session building, planning, syncing, and reviewing — not learning the theory.
