+## How to make translation of CamiTK in other language ?
+
+The language used in implementation code by camiTK is english. but if
+you want to use an another language you can use QtLinguist
+(Linguist.exe) to translate all the english character strings.
+
+What is the step to install a new language translation ?
+
+1.  in CamitkTranslate.cmake you must insert abreviation of new language
+    like \_en\_fr\_de for english, french and german.
+2.  do cmake (the files translate\_en.ts, translate\_fr.ts ,
+    translate\_de.ts are created or updated for all extensions).
+3.  use QtLinguist with your \*.ts files to translate character string
+    of \*.cpp, \*.ui, \*.h files.
+4.  do cmake (the file translate\_en.qm, translate\_fr.qm ,
+    translate\_de.qm are create or update for all extensions).
+5.  update the listLanguageAndFlag variable in changeLanguage.cpp to
+    insert for the new language his name, abreviation and flag (add
+    flag\_xx.png file in png format in
+    src\\sdk\\actions\\application\\resources\\flags\\16 directory)
+6.  compile camitk. (then all translate\_xx.qrc file are
+created).
+
+## How to make translation of CamiTK in other language just for one extension ?
+
+  - open the extension CMakeLists.txt and add
+    **EXTRA\_TRANSLATE\_LANGUAGE** with language.
+
+```cmake
+camitk_extension(ACTION_EXTENSION
+                 DEFINES COMPILE_APPLICATION_ACTION_API
+                 CEP_NAME SDK
+                 DESCRIPTION "Features actions used at application level (these actions are mandatory for any CamiTK application to work"
+                 EXTRA_TRANSLATE_LANGUAGE de
+         )
+```
+
