Step 2 - language configuration

Now go to the Extensions -> Language Manager and click New button.

Fill in the following fields of New Content Language:

1. Title - type a name of language. It will appear on our list.
2. Title Native - it’s title of native language. In my case I type Polski (PL)
3. Language Tag - enter a language tag. This should be the exact prefix used for the language you want to install. How to find it? Go to Extensions-> Language Manager and look at Language tag column and find Your item- that’s it! In my case it’s: pl-PL
   
   
   
4. URL Language Code - this language code will be appended to the site URL. It have to be an unique name among all of languages!
5. Image Prefix - if you want to use state flag that represents the language as sign, select one from the drop-down list.
6. Status - define for which users language will be available.
7. Access - also specify it for groups of users.
8. Description - it’s an optional field, you can type a description for this language.

Click Save and close. The following message should appear:

Step 3 - Language Filter plugin

Now we need to enable the plugin responsible for displaying the content depending of selected language. Go to Extensions-> Plugin Manager and find System- Language Filter. If it’s disabled (button with cross on red background) enable it by clicking in button.

Step 4 - Language switcher module

Now it's time for displaying language switcher/selector module on the site. Go to Extensions-> Module Manager and click New. Choose Language switcher from list.

Type a name of the module and choose a layout position for a module. You can hide title of module, too.

Go to Menu Assigment tab and assign a module to all pages. Click Save and close.

Step 5 - configuring main menu for each language

Now we need to create a menu that will keep info about you languages. At first let's create the menu for default language. Go to Menus-> Menu Manager-> Add New Menu.

Type Title and Menu Type, for example:

Click Save and close.
Go to Menus-> Main Menu -> Home page item.

Click Save as Copy

Fill in the fields like that:

1. Title (title of home page in your default language)
2. Menu location (location of created menu)
3. Status (Published if you want that every viewers see it)
4. Default Page -> Yes
5. Language- choose Your language

Click Save and Close

If everything is in order You should see:
