+# SystemC hello world
+
+Miniaml example how to run SystemC without installation
+
+## Compiling SystemC
+
+Downloadin and compiling systemc framework
+
+```bash
+curl http://www.accellera.org/images/downloads/standards/systemc/systemc-2.3.2.tar.gz --output systemc-2.3.2.tar.gz
+tar -xvf systemc-2.3.2.tar.gz
+cd systemc-2.3.2/
+./configure
+```
+
+
+## Prepare Makefile
+
+After compilation of systemc libraries we can create "Hello World" example.
+
+```bash
+SYSTEMC_PATH=/home/user/downloads/source/systemc/systemc-2.3.2
+SYSTEMC_INC=$(SYSTEMC_PATH)/src
+SYSTEMC_LIB=$(SYSTEMC_PATH)/src/.libs
+
+make:
+	g++ hello_world.cpp -I$(SYSTEMC_INC) -L$(SYSTEMC_LIB) -Wl,-rpath=$(SYSTEMC_LIB)\
+		-o hello_world -lsystemc -lm
+```
+
+```c
+#include "systemc.h"
+
+SC_MODULE (hello_world) {
+	SC_CTOR(hello_world) {
+
+	}
+
+	void say_hello() {
+		cout << "Hello world\n";
+	}
+};
+
+int sc_main(int argc, char **argv) {
+	hello_world hello("HELLO");
+	hello.say_hello();
+	return(0);
+}
+```
+
+after compilation try to run
+
+```bash
+./hello_world
+```
+
+output of this example is
+
+```bash
