Add an "ExtraLocales=(iso 639-1 language code)" in the file eReader.conf
You have a new language on the list.
2. Copy the dictionary files to Kobo.

KOBO requires a special file naming for dictionaries.
Example: dicthtml-en-pl.zip - from english to polish.
Rename files and copy to "\.kobo\dict\".
3. Update database file.
I use Sqlite Manager plugin for Mozilla Firefox.
Open \.kobo\KoboReader.sqlite file.
(Database->Connect database -> indicate file KoboReader.sqlite).
In the left window find Tables -> Dictionary.
In the right window click "Add".
Sufix- file name without "dicthtml".
Name- name on the list of dictionaries.
Installed-true.
Size- file size in BYTES.
Issynced- true.
Click OK 2 times.
Close the database file (Database->Close Database).
Congratulations, you have a new dictionary.
Sorry for my english.
