+When MATLAB starts, it will look for a **pathdef.m** file in its startup directory. It should not be edited - leave the default MATLAB path containing only MATLAB native toolboxes. The rest should be configured dynamically, as explained below.
-Start up folder (in the MATLAB icon | Properties | Start in ) (e.g. F:\Dropbox\Sources\Repos\matlab_config\MATLAB2014) allows controlling different paths and other settings via **startup.m** file placed in this folder, e.g.:
+If a custom **startup.m** is found on the path, it will be executed: https://www.mathworks.com/help/matlab/ref/startup.html
+There are __two ways__ to configure place the startup.m on the path:
+. Custom startup folder set via MATLAB icon: (right click on the MATLAB icon | Properties | Start in ) (e.g. F:\Dropbox\Sources\Repos\matlab_config\MATLAB2014) allows controlling different paths and other settings via **startup.m** file placed in this folder.
+. Place custom startup.m to your [[https://www.mathworks.com/help/matlab/ref/userpath.html|userpath]]
+(type 'userpath' in the MATLAB command window to figure out yours).
+For example, a minimal **startup.m** for automatically including all GitHub repositories (but excluding not needed internal .git folders) can be just:
+<code matlab>
+addpath(genpath_exclude('YOUR_PATH_TO_REPOS','.git'));
+</code>
+**Note:** [[https://github.com/igorkagan/matlab_config/blob/master/MATLAB2014/genpath_exclude.m|genpath_exclude.m]] should also be placed in the startup folder.
+Example startup.m for GitHub repositoriesand Fieldtrip and NeuroElf from DAG server (Y:):

+disp('Welcome to YOUR MATLAB VERSION, e.g. MATLAB2014a');
+addpath(genpath_exclude('YOUR_PATH_TO_REPOS','.git')); %<--- !!! change 'YOUR_PATH_TO_REPOS'
