+# EX01: Guessing Game
+
+Welcome to CSE 332! This is your first programming assignment of the course. We will also help you get your computer set up for future assignments.
+
+"Guessing Game" is a game with two parties: the "chooser" and the "guesser":
+- The "chooser" picks a natural number larger than zero, and when given a guess, will return whether if the real answer is higher or lower. 
+- The "guesser" must guess what the number is by repeatedly making guesses to the "chooser" until the
+correct answer is found.
+
+## Tasks
+
+### Set Up
+
+Before you begin, go through the [Setting Up Your CSE 332 Environment](https://docs.google.com/document/d/1CWj02e1xjJY0J3CG_1tDxiOlDMnd2GU9PKmS5sskfXU/edit?usp=sharing)
+handout. This will prepare your development environment for both this assignment and future programming projects.
+
+After you have IntelliJ and Git set up, follow the instructions on that document to clone the repository that we individually generate for 
+everyone. You should be cloning `ex01-yourNetID`, instead of `ex01-public`. 
+
+### Completing the Exercise
+
+Write Java code for `findNumber()`, a method that simulates the "guesser" in a guessing game by making a series of guesses
+and returning the correct answer.
+
+You should not have to bruteforce the number one-by-one. If the number chosen is $`n \geq 2`$, your code may make at
+most $`2 \log_2(n)`$ guesses. What kind of algorithm (that you've learned from CSE 143) should you be using here to achieve
+this complexity class?
+
+Also note that there is no upper bound on the number the "chooser" can pick, so this is not something that you should
+hardcode.
+
+Open `src/main/java/Guesser.java` to get started. It might also be helpful to take a look at the `Chooser.java`
+interface; however, you should only edit the method `findNumber` in `Guesser.java`. When you are not sure about what behavior 
+to implement, be sure to check the method's comments _and_ any potential parent classes that it extends/implements -- this 
+technique will become extremely important in the projects.
+
+This repository will not contain the testing code for the staff `Chooser` which will be used to autograde your exercise.
+However, if you just want to test if you have set up IntelliJ and Java correctly, you can click the green Run arrow
+in `src/test/java/TestDummy.java` to run a sample test to test compilation.
+
+### Submission on Gradescope
+
+Log into Gradescope [here](https://www.gradescope.com/saml) using your UW email. If you do not see CSE 332, let the course staff know using a private Ed post or by writing to `cse332-staff@cs`.
+
+If this is your first time submitting a coding assignment on Gradescope, take a look at
+the [Submitting Projects](https://docs.google.com/document/d/155QBmHj9ztkvulFDS0f3UDZq_Tz8b7M2HR-aVfcBzQI/edit) handout.
+Remember to use the GitLab option on Gradescope instead of uploading files directly.
+
+### Grading
+Submit on Gradescope to get your grade. There are no hidden tests for EX01, so the percentage that you see on Gradescope is your final grade.
+
+### Important Notes
+1. Avoid using `System.out.println()` when running the autograder. If you use any print statements, always remove them -- they perform poorly with large datasets. 
+2. There is a small buffer on top of the $`2\log_2(k)`$ to handle scenarios such as when $`n = 2`$.
