-# Checkstyle intro
+# Checkstyle Introduction
+
+In this repository, you will find code that has some code style issues. Your task is to identify and fix all the checkstyle issues.
+
+First, try to review the code independently to detect the code style issues and fix them. When you are ready, you can execute the `mvn clean package` command. Observe the console output, where you will either see a message indicating that the build was successful, or a list of code style issues that need to be addressed.
+
+Continue to fix all code style issues until you receive console output similar to this:
+```text
+...
+
+[INFO] 
+[INFO] --- maven-checkstyle-plugin:3.1.1:check (default) @ diamond ---
+[INFO] Starting audit...
+Audit done.
+[INFO] You have 0 Checkstyle violations.

+> NOTE: Some parts of the console log have been omitted and replaced with `...`.
+
+> NOTE 2: Pay special attention to the lines `[INFO] You have 0 Checkstyle violations.` and `[INFO] BUILD SUCCESS`. These lines indicate the successful completion of our task.
+
+Once you are ready, don't forget to create a PR with your solution and verify all GitHub checks passed.
+
+Good luck!
