+#### unresolved
+
+Show files that are found in includes but didn't found in file system.
+One of the resean is missing includes files, for example:
+There is file *main.cpp*, folder *include* that store file *header.hpp* :
+
+```
+tree
+.
+├── include
+│   └── header.hpp
+└── main.cpp
+
+```
+
+If run *cppinclude* result will be:
+
+```
+cppinclude --report=unresolved
+Start initialization project ...
+Start analyze sources ...
+Start report results ...
+Unresolved files:
+1. "header.hpp" isn't resolved in:
+    1. "main.cpp" line: 1
+
+```
+
+But if add folder *include* to *include_dirs* resultat will be empty:
+
+```
+cppinclude --report=unresolved --include_dirs=include
+```
+
+[Back to top](#cppinclude)
+
+#### most_impact
+
+Show how many files will be recompiled with header will be changed.
+Example from [docs/examples/simple_example/](docs/examples/simple_example/)
+
+```
+cppinclude --report=most_impact
+...
+Most impact files:
+1 : "char_kind.hpp" impact on 11 file(s)
+Included by:
+   1 : "base_char.hpp" line 3, impact on 10 file(s)
+2 : "base_char.hpp" impact on 10 file(s)
+Included by:
+    1 : "base_char_factory.hpp" line 3, impact on 5 file(s)
+    2 : "char_a.hpp" line 3, impact on 2 file(s)
+    3 : "char_b.hpp" line 3, impact on 2 file(s)
+3 : "base_char_factory.hpp" impact on 5 file(s)

+    2 : "char_b_factory.hpp" line 3, impact on 2 file(s)
+...
+```
+
+It means if file char_kind.hpp will be changed 11 files are recompiled.
+
+[Back to top](#cppinclude)
+
+#### unincluded
+
+Show files that are found in file system but didn't found in includes.
+It often happens after refactoring when file that include header was deleted.
+Example from [docs/examples/simple_example_with_unincluded_headers/](docs/examples/simple_example_with_unincluded_headers/)
+
+```
+cppinclude --report=unincluded
+Start initialization project ...
+Start analyze sources ...
+Start report results ...
+Unincluded headers:
+1 : "config.hpp"
+2 : "settings.hpp"
+
+```
+
+**Limitations:**
+
+* Header with same names: 
+
+If headers have same name but are located in different folders will be found 
+only first header and other will be unincluded. 
+For example: *lib1/header.hpp*, *lib2/header.hpp* and
+*main.cpp* : 
+
+```c++
+#include "header.hpp"
+...
+```
+Result will be:
+
+```
+cppinclude --include_dirs=lib1,lib2 --report=unincluded
+
+Start initialization project ...
+Start analyze sources ...
+Start report results ...
+Unincluded headers:
+1 : "lib2/header.hpp"
+
+```
+
+* Empty result for CMake project: 
+
+If analyze CMake project ( generated file compile_commands.json ) 
+result will be empty. Because in current implementation *cppinclude* analyze 
+source files on file system or files from compile_commands.json
+
+* Header files are files that have extension started with *h* letter
+
+***All limitations will be fixed in future releases ***
+
+
+[Back to top](#cppinclude)
+
+#### different_type
+
+Show headers that are included in different ways.
+It helps to follow code style in project,
+for example include third party libraries in <...> and project header in "...".
+Example from [docs/examples/simple_example_for_different_type_report/](docs/examples/simple_example_for_different_type_report/)

+```
+cppinclude --report=different_type
+Start initialization project ...
+Start analyze sources ...
+Start report results ...
+Files that are included by different ways:
+1. base_char.hpp
+With double quotation marks ( #include "..." ) in files:
+    1. base_char_factory.hpp line 3
+    2. char_b.hpp line 3
+With angle brackets ( #include <...> ) in files:
+    1. char_a.hpp line 3
+2. base_char_factory.hpp
+With double quotation marks ( #include "..." ) in files:
