+How To Add a New Translation
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+1. Clone the git://git.gnome.org/gimp-help-2 repository.
+
+2. Open 'configure.ac' file in a text editor.
+
+3. Got to this line:
+
+ALL_LINGUAS="ca da de el en en_GB es fr it ja ko nl nn pt_BR ro ru zh_CN"
+
+4. Add a two-letter or four-letter code for your language, e.g. 'ro' for 
+Romanian or 'es_MX' for Spanish (Mexico). Save the file.
+
+5. Run './autogen.sh' to generate a Makefile.
+
+6. Run 'make po-LANG' to generate PO files for your langauge, where LANG 
+is either the two-letter or four-letter code that you added.
+
+
+How To Translate
+~~~~~~~~~~~~~~~~
+
+Use any PO editor you prefer (poEdit, Gtranslator, Lokalize etc.) to open 
+and translate PO files create at the previous step. Don't forget to fill 
+in basic metadata like translator's name and email address.
+
+How To Test Translation
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Run 'make html-LANG', where LANG is your two/four-letter language code, 
+to generate HTML version of the user manual.
