Language definition files for front-end templates are stored in

[path-to-Joomla]/language/[ln-LN]

where [ln-LN] is the language code. Language codes are defined in RFC3066 The file must be named

[ln-LN].tpl_[template-name].ini

where [template-name] is the name of the template (in lowercase). For example, the British English language file for the Beez template is

[path-to-Joomla]/language/en-GB/en-GB.tpl_beez.ini

You should also create a separate language file for translating the Administrator back-end of your template. This will be stored in

[path-to-Joomla]/administrator/language/[ln-LN]

but the file naming convention is the same.

For administrator templates, as distinct from front-end templates, the second of these files is the only one required. For example, the British English language file for the Khepri administrator template is located in

[path-to-Joomla]/administrator/language/en-GB/en-GB.tpl_khepri.ini
