+As it says in the webpage, can download it at [[https://github.com/raspberrypi/tools]]. I've
+downloaded the tools in ~/tools-master. So, because my linux system is 64 bits, the path
+for the compiler is in ''~/tools-master/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin''.
+===== Create your first project in eclipse =====
+Don't forget the path in the previous step, because you will need to create your first hello world
+project in eclipse.
+Let's go for it: first, open eclipse and click on "File -> New -> C/C++ Project":
+{{ :raspberrypi:step01.png?nolink&600 |}}
+Then, pick up "C++ Managed build" or "C Managed buid", whichever you prefer. I've chosen C++ Managed build:
+{{ :raspberrypi:step02.png?nolink&600 |}}
+Next, I've selected the empty project and, very important, pick up "Cross GCC" to select a cross compiler:
+{{ :raspberrypi:step03.png?nolink&600 |}}
+On the screen that appears, you can click on next:
+{{ :raspberrypi:step04.png?nolink&600 |}}
+This is the important part: when you have to select the g++ cross compiler. In the previous section I've spotted that and took note of the path and the prefix to use here:
+{{ :raspberrypi:step05.png?nolink&600 |}}
+However, if you are unsure which to use, you can try several. A good option is to try to execute the
+cross compiler to see if it runs: at least it has to execute properly in your computer. At the end,
+this is a cross compiler, isn't it?
+Finally, you will get the project on eclipse:
+{{ :raspberrypi:step06.png?nolink&600 |}}
+Then, right-click on new -> source file and tye something like this:
+<code cpp>
+/*
+ * main.cpp
+ *
+ *  Created on: 31 mar. 2018
+ *      Author: dictinio
+ */
+#include <iostream>
+int main( int argc, char *argv[] )
+{
+	std::cout << "hello world!!!" << std::endl;
+}
+</code>
+And compile it. At this point it's very important to have some experience with C++ and/or eclipse. It's
+not the purpose of this tutorial to teach you to use the eclipse IDE, to do that, probably
+you will have to read other tutorials.
+===== Compile and run =====
+Build the program and copy it to your raspberry: it should run smoothly in the raspi. Obviously, it
+won't execute locally.
+===== Execute and run in the raspberry pi remotely =====
+Eclipse CDT has facilities to move every build in the raspberry pi and execute it remotely.
+NEXT STEP: debug remotely.
