+
+# Tutorial 1: Hello World #
+
+This tutorial will guide you through the necessary steps to build your first "Hello World" example. Make sure you have read the [Setting up the development environment](devenv-setup.md) guide first!
+
+Don't be afraid, there is very little code in this first tutorial. The main goal is to learn how to build and execute an application using the EFL library. Should we start?
+
+## The Program ##
+
+Copy the following program into a text file named ``hello-world.c``:
+
+```c
+#include <Eina.h>
+#include <Efl.h>
+#include <Elementary.h>
+
+EAPI_MAIN void
+efl_main(void *data EINA_UNUSED, const Efl_Event *ev)
+{
+   Efl_Loop_Arguments *args = ev->info;
+
+   if (eina_array_count(args->argv) == 0)
+     {
+        printf("Hello World!\n");
+     }
+   else
+     {
+        printf("Hello %s!\n", (char *) eina_array_data_get(args->argv, 0));
+     }
+
+   efl_exit(0);
+}
+
+EFL_MAIN()
+```
+
+Now build the application as described in the [Setting up the development environment](devenv-setup.md#Building) guide. As a quick reminder, this is the required command if you are using the `gcc` compiler:
+
+```bash
+gcc -o hello-world hello-world.c `pkg-config --cflags --libs eina efl elementary` -DEFL_EO_API_SUPPORT=1 -DEFL_BETA_API_SUPPORT=1
+```
+
+If you got no warnings in the process, your program should be ready. Go ahead and test it! Just type:
+
+```bash
+./hello-world
+```
+
+And you should se the words `Hello World!` printed on the screen. Moreover, if you provide your name to the program in the command line:
+
+```bash
+./hello-world Mike
+```
+
+You should be greeted personally: `Hello Mike!`
