 You have installed the latest release of Auryn and [[manual:compileauryn|compiled the library]]. Suppose you now want to start writing your own code. A good way to start is by modifying [[examples:start]]. First copy the file to a place where you would like to develop your Auryn code. You could for instance create the directory ''~/mycode/'' for that purpose. Start with copying the example there (for instance  ''sim_epsp''). It is probably a good idea to rename the program too. Let's assume you called it ''sim_new.cpp''.  You have installed the latest release of Auryn and [[manual:compileauryn|compiled the library]]. Suppose you now want to start writing your own code.

 I like using my own handwritten makefiles (of course you can follow any other approach you feel most comfortable with). To proceed with my approach create a file called ''Makefile'' with the following contents: I like using my own handwritten makefiles (of course you can follow any other approach you feel most comfortable with).

 Here you might need to update the first three lines if something does not work for you. The first line is the shorthand for you MPI C++ compiler, the second line is the path the root directory where you keep Auryn. Finally, in the third we set the directory where you keep ''libauryn.a''. Per default that is where you build Auryn. Here you might need to update the first three lines if something does not work for you.
