+## Connection of external repository
+Embox allows connection of external repo for modules and templates. To connect them to each other, it's enough to specify root directory of repository:
+```
+    make ext_conf EXT_PROJECT_PATH=<your projects path>
+```
+To make templates visible through "make confload" and "make confload-" calls, connected repo has to have the next folder-structure:
+```
+    <root_folder>/<project_name>/templates
+```
+Modules can be in random folders. Search is carried out, using *Mybuild* and **.my* files.
