-## Getting started
+## Features
+
+- Automatically generate test case outputs when provided input files and reference solutions
+- Run batch test cases on problems
+- Easily switch between languages when testing solutions
+- Check/validate problems to ensure things are correct (e.g. no missing test cases)
+- Easy management and organisation of problems and competitions with options to create, rename, archive, and more
+
+Planned:
+
+- Automatic formatting of problems and solution files
+- Uploading problems and test cases to an online judge
+- Testing code within judge environments
+- Improve checking/validation of problems, covering more criteria
+- Shell auto completions
+
+## Install
 
 Make sure you have Rust installed. Build the binary:
