 ## Build the project
 
 ### Compile
 
 Binaries will be placed inside the `bin` directory. To build the project just run:
 ```bash
-make
+$ make
 ```
 
+If `make` is not installed in your machine, then go the old way:
+```
+$ g++ -O2 -Wall -Wextra -Wfatal-errors -pedantic -Iinclude src/*.cpp -o bin/main
+```
+
+> [!IMPORTANT]
+> This `g++` command uses some compilations flags to show relevant warnings.
+> A more detailed documentation on these flags is located [here](https://bytes.usc.edu/cs104/wiki/gcc/).
+
 ### Build & run
 
 To compile and run the application:
 ```bash
-make run
+$ make run
+```
+
+Or just run the following command from the root directory
+```
+$ ./bin/main
 ```
 
 ### Clean `bin` directory
 
 Clean the `bin` directory using the following command:
 ```bash
-make clean
