+| # | Parent | Description |
+| - | -------| ----------- |
+| \<root-path\> | - | Path to your project. Hold master CMakeLists.txt and general files of your projects. |
+| conf.d | \<root-path\> | Holds needed files to build, install, debug, package an AGL app project |
+| app-templates | conf.d | Git submodule to app-templates AGL repository which provides CMake helpers macros library, and build scripts. config.cmake is a copy of config.cmake.sample configured for the projects. SHOULD NOT BE MODIFIED MANUALLY !|
+| autobuild | conf.d | Scripts generated from app-templates to build packages the same way for various platforms.|
+| cmake | conf.d | Contains at least config.cmake file modified from the sample provided in app-templates submodule. |
+| wgt | conf.d | Contains at least config.xml.in template file modified from the sample provided in app-templates submodule for the needs of project (See config.xml.in.sample file for more details). |
+| packaging | conf.d | Contains output files used to build packages. |
+| \<libs\> | \<root-path\> | External dependencies libraries. This isn't to be used to include header file but build and link statically specifics libraries. | Library sources files. Can be a decompressed library archive file or project fork. |
+| \<target\> | \<root-path\> | A target to build, typically library, executable, etc. |
+
+### Update app-templates submodule
+
+You may have some news bug fixes or features available from app-templates
+repository that you want. To update your submodule proceed like the following:
+
+```bash
+git submodule update --remote
+git commit -s conf.d/app-templates
+```
+
+This will update the submodule to the HEAD of master branch repository.
+
+You could just want to update at a specified repository tag or branch or commit
+, here are the method to do so:
+
+```bash
+cd conf.d/app-templates
+# Choose one of the following depending what you want
+git checkout <tag_name>
+git checkout --detach <branch_name>
+git checkout --detach <commit_id>
+# Then commit
+cd ../..
+git commit -s conf.d/app-templates
