 1. First, run the reference parser to get an AST JSON:
 ```

 2. Second, run the reference analysis on the AST JSON to get a typed AST JSON:
 ```
-java -cp "chocopy-ref.jar:target/assignment.jar" chocopy.ChocoPy --pa2 chocopy.reference.RefAnalysis --in <ast_json_file> --out <typed_ast_json_file>

 3. Third, run your code generator on the typed AST JSON to get a RISC-V assembly file:

 The `src/tests/data/pa3/sample` directory already contains the typed AST JSONs for the test programs (with extension `.out.typed`); therefore, you can skip the first two steps for the sample test programs.

 ### Chained commands
 
-For quick development, you can chain all the stages `--pa1`, `--pa2`, `--pa3`, and `--run` to directly execute a ChocoPy program:

 You can omit the `--run` in the above chain to print the generated assembly program instead of executing it.
 
 ### Running the reference implementation
 
-To observe the output of the reference implementation of the code generator, replace the class `chocopy.pa3.StudentCodeGen` with `chocopy.reference.RefCodeGen` in any command where applicable.
