 You will use C++ to develop your EEROS applications. For this you need at least some knowledge of the basic language features. A good starting point might be [[https://www.cplusplus.com/doc/tutorial/]]. Minimal help can also be found under [[tools:cplusplus|]].
+All the necessary libraries are already on our images, notably eeros, librobotcontrol and bbblue-eeros.
 What do you want to do next?

 ===== Say Hello with EEROS =====
-  - Fetch the [[https://github.com/eeros-project/eeros-build-scripts.git|EEROS scripts]] on your host and checkout the branch for the Beaglebone Blue <code>
-$ git clone https://github.com/eeros-project/eeros-build-scripts.git eeros-project
-$ cd eeros-project
-$ git checkout sdk_bbb
-</code>
-  - Edit the file ''config.sh.in'' as follows <code>
-custom_application=hello
-</code>
   - Create a project directory and change into it with <code>
 $ mkdir hello

-  - Change back into your parent directory and build the project with <code>
+  - Create a build directory and change into it with <code>
-$ cd ..
+$ mkdir build-armhf
-$ ./make.sh
+$ cd build-armhf

+$ . ~/ost-devel/1.0/environment-setup-cortexa8hf-neon-poky-linux-gnueabi

+  - Build the project with <code>
+$ cmake ..
+$ make

   - Make changes to "main.cpp", save them and rebuild with <code>
-$ ./make.sh

 </code> In order to be able to write your own EEROS programs, you could use any text editor. However, we recommend to use an integrated development environment, see [[getting_started:kdevelop|]].
