+# Compiler Design Project
+### How to Compile the Source Code
+- Run the Makefile in the root directory and `./compiler` executable will be built.
+
+### How to Compile the Sample Program
+- Run `run.sh` or `./compiler < input.txt > out.c 2> err.log`. This will generate a C program named `out.c` and show any compilation errors in `err.log`.
+- Run `gcc -o program out.c` to compiler the generated program.
+- Test the generated program by running `./program`.
