How to support a new language to the front site of my component?

Question

I'm developing a component and want to set up multiple language support at least for the front end at this stage.

I may have missed something or not interpreted it correctly but in the Joomla component development tutorial.

I think only adding language for the back is discussed; Under the section "Adding language translation in the public site" the site/language/en-GB/en-GB.com_helloworld.ini file is left empty.

I could not find anything else later or earlier in the tutorial.

Appreciate your help.

You only have to add the additional languages to the XML installer of your extension. For example:

<?xml version="1.0" encoding="utf-8"?>
<extension type="component" version="2.5.0" method="upgrade">
...

    <!-- Front end translation files -->
    <languages folder="language/frontend">
        <language tag="en-GB">en-GB/en-GB.todo_cli.ini</language>
        <language tag="en-GB">en-GB/en-GB.com_todo.ini</language>
        <language tag="es-ES">es-ES/es-ES.com_todo.ini</language>
        <language tag="es-ES">es-ES/es-ES.com_todo.sys.ini</language>       
    </languages>

...

    <!-- Administrator back-end section -->
    <administration>
..
        <!-- Back-end translation files -->
        <languages folder="language/backend">

            <language tag="en-GB">en-GB/en-GB.com_todo.ini</language>
            <language tag="en-GB">en-GB/en-GB.com_todo.sys.ini</language>
            <language tag="es-ES">es-ES/es-ES.com_todo.ini</language>
            <language tag="es-ES">es-ES/es-ES.com_todo.sys.ini</language>

        </languages>
    </administration>
..
</extension>

Ini files follow the usual format. Example:

; ToDo Project
; Copyright (C) 2014 - 2014 MYCOPYRIGHT. All rights reserved.
; License GNU General Public License version 2 or later; see LICENSE.txt, see LICENSE.php
; Note : All ini files need to be saved as UTF-8 - No BOM

COM_TODO_ALIGN="Image Float"
COM_TODO_ALIGN_DESC="This will apply the classes 'pull-left', 'pull-center' or 'pull-right' to the '<figure>' or '<img>' element"
COM_TODO_BROWSE_FILES="Browse files"
COM_TODO_CAPTION="Caption"
COM_TODO_CAPTION_CLASS_LABEL="Caption Class"
