+# c_command_pattern
+
+a simple example of how to implement the state pattern in c. check [`main.c`](src/main.c) for the implementation
+
+# how to build and run it
+
+this demo uses a simple build system called [nob](https://github.com/tsoding/nob.h) a header only build system for c projects.
+
+to build run these command in the root of the project:
+```bash
+
+# bootstraps the build system
+> gcc nob.c -o nob
+
+# runs the build system
+> ./nob
+
+# runs the program
+> ./build/main 
+
+```
+and if you have a differnt complier you want to use that is posix compliant just change the `CC` macro in the `nob.c` with your one.
