+Stage 0 introduces students to the basics of Java,
+which is the programming language that is used throughout the learning course.
+
+<Aside type="note">
+    Though it is not part of Stage 0, students are expected to go through the
+    Course Setup. This ensures that students have the tools needed to follow
+    along.
+</Aside>
+
+When learning Java, there are many topics to cover.
+Therefore, Stage 0 focuses mainly on the topics that are useful for programming an FRC robot.
+For students who are new to programming, it’s important for them to follow stage 0 in order.
+This will help ensure that important information is not missed.
+
+The topics covered are:
+
+- Java fundamentals
+- Debugging
+- Operators
+- Conditionals
+- Loops
+- Classes and Objects
+- Methods and Mutable State
+- Arrays and For-Each Loops
+- Interfaces, Generics, and Lists
+
+Each page has a set of exercises that students should complete.
+This will help them build understanding of each new topic.
+By the end of the stage, students will have enough foundational Java knowledge to be able to follow the rest of the learning course.
+
+## Learning Objectives
+
+By the end of Stage 0, students should be able to:
+
+- Read and write basic Java syntax
+- Identify code errors and solve them
+- Use Arithmetic, Assignment, Comparison, Logical operators to change, or compare the values of variables
+- Implement conditionals and loops
+- Define classes
+- Create and use objects
+- Define methods
+- Create Arrays and iterate through them using for-each loops
+
+## Common Issues to Watch Out For
+
+- Forgetting to add a semi-colon
+- Mismatching or forgetting opening and closing curly braces
+- Variable names having inconsistent capitalization
+- Infinite loops
+- Using single equals `=` instead of double `==` for comparisons
+
+## Additional Practice
