+## Representing State
+Leo allows users to define composite data types with the `struct` keyword. 
+The game board is represented by a struct called `Board`, which contains three `Row`s.
+An alternative representation would be to use an array, however, these are not yet supported in Leo.
+
+## Language Features
+- `struct` declarations
+- conditional statements
+- early termination. Leo allows users to return from a function early using the `return` keyword.
+
+## Running the Program
+
+Leo provides users with a command line interface for compiling and running Leo programs.
+Users may either specify input values via the command line or provide an input file in `inputs/`.
+
+### Providing inputs via the command line.
+1. Run 
+```bash
+leo run <function_name> <input_1> <input_2> ...
+```
+See `./run.sh` for an example.
+
+
+### Using an input file.
+1. Modify `inputs/tictactoe.in` with the desired inputs.
+2. Run
+```bash
+leo run <function_name>
+```
+
+## Executing the Program
+```bash
+leo execute <function_name> <input_1> <input_2> ...
+```
+
+## Playing the Game
+
+### 1. Create a new game board
+```bash
+leo run new
+```
