 Getting started
 ===============
 
+Getting started may be the most challenging part of every new library.
+This guide is describing how to start with the library quickly and effectively

 Download library
 ^^^^^^^^^^^^^^^^
 
 Library is primarly hosted on `Github <https://github.com/MaJerle/lwshell>`_.
 
-* Download latest release from `releases area <https://github.com/MaJerle/lwshell/releases>`_ on Github
-* Clone `develop` branch for latest development
+You can get it with:
+
+* Downloading latest release from `releases area <https://github.com/MaJerle/lwshell/releases>`_ on Github
+* Cloning ``master`` branch for latest stable version
+* Cloning ``develop`` branch for latest development

 Add library to project
 ^^^^^^^^^^^^^^^^^^^^^^
 
 At this point it is assumed that you have successfully download library, either cloned it or from releases page.
+Next step is to add the library to the project, by means of source files to compiler inputs and header files in search path
 
-* Copy ``lwshell`` folder to your project
-* Add ``lwshell/src/include`` folder to `include path` of your toolchain
-* Add source files from ``lwshell/src/`` folder to toolchain build
+* Copy ``lwshell`` folder to your project, it contains library files
+* Add ``lwshell/src/include`` folder to `include path` of your toolchain. This is where `C/C++` compiler can find the files during compilation process. Usually using ``-I`` flag
+* Add source files from ``lwshell/src/`` folder to toolchain build. These files are built by `C/C++` compiler
 * Copy ``lwshell/src/include/lwshell/lwshell_opts_template.h`` to project folder and rename it to ``lwshell_opts.h``
 * Build the project
 
 Configuration file
 ^^^^^^^^^^^^^^^^^^
 
+Configuration file is used to overwrite default settings defined for the essential use case.
 Library comes with template config file, which can be modified according to needs.
-This file shall be named ``lwshell_opts.h`` and its default template looks like the one below.
+and it should be copied (or simply renamed in-place) and named ``lwshell_opts.h``
 
 .. note::
     Default configuration template file location: ``lwshell/src/include/lwshell/lwshell_opts_template.h``.
-    File must be renamed to ``lwshell_opts.h`` first and then copied to the project directory (or simply renamed in-place) where compiler
+    File must be renamed to ``lwshell_opts.h`` first and then copied to the project directory where compiler
     include paths have access to it by using ``#include "lwshell_opts.h"``.
 
-.. tip::
-    Check :ref:`api_lwshell_opt` section for possible configuration settings
+List of configuration options are available in the :ref:`api_lwshell_opt` section.
+If any option is about to be modified, it should be done in configuration file

+
+.. note::
+    If you prefer to avoid using configuration file, application must define
+    a global symbol ``LWSHELL_IGNORE_USER_OPTS``, visible across entire application.
+    This can be achieved with ``-D`` compiler option.
 
 Minimal example code
 ^^^^^^^^^^^^^^^^^^^^
 
-Run below example to test and verify library
+To verify proper library setup, minimal example has been prepared.
+Run it in your main application file to verify its proper execution
