 ## How to run the code
 
 - To run the code, follow the steps below:
-  - Open the terminal
-  - Navigate to the directory where the code is stored
-  - Run the following commands:
-    - `flex <filename>.l`
-    - `gcc lex.yy.c -lfl`
-    - `./a.out`
-  - The output will be displayed on the terminal
-
+  - Open terminal and navigate to the directory `Compiler-Design/`
+  - Run the following command to compile the code:
+    ```shell
+    bash build.sh
+    ```
+  - This will compile the code and generate an executable file named after the code file.
+  - To run the code, run the following command:
+    ```shell
+    ./<executable_file>
