# Adding a new translation language

If you need to add new language to the application, you will need to create your own language files.

Please create a copy of the **English (en)** language files:

**\language\core-en.po**
**\language\core-en.mo**


Then, rename them accordingly to your new language. If you review the file **\library\Zend\Locale\Data\Translation.php** and search your new language on the array **$languageTranslation** you will find a code for the language, for example: **'Serbian' => 'sr'** so you need to rename the new files using the code of the new language, for example:

**\language\core-sr.po**
**\language\core-sr.mo**

Now, it is time to start the translations. You will need to open the files \language\core-sr.po and language\javascript-sr.po, and add your translations there. You can use a free editor like [Poedit](https://poedit.net/download).

Any time you change the file **\language\core-sr.po**, you need to convert it to **\language\core-sr.mo**, which is the binary file that Clientexec uses to load translations. If you are using **Poedit** you can easily generate the .mo file from there. If you are not using \*\*Poedit \*\*then we have made a tutorial video on how to generate a .mo file: [https://www.screencast.com/t/h2zAKFcKi](https://www.screencast.com/t/h2zAKFcKi)

The video just shows the following:

* Opening a language file to add translations or modifying an existing one. In the video, the file edited is for the Spanish language **\language\core-es.po** but for the example it should be **\language\core-sr.po**
* After adding your changes to the file, then the video shows a web site ([https://localise.biz](https://localise.biz/)) that you can open, then at the bottom of the site there is a menu where you can select "Language pack converter" ([https://localise.biz/free/converter](https://localise.biz/free/converter)), select your edited language file, configure what you will generate, in this case, you select the "Source language" and the format for the file (In the example: **Serbian**, and **.MO** file [To: > Gettext > Gettext MO (binary)]), and then you convert the file on the site and save the new file.
* Then you need to rename the new file consistently with the one you used, so for the example you need it to be renamed to core-sr.mo
* Then, you will need to place the file on the proper location **\language\core-sr.mo**
* Finally, make sure the file has read permissions, and you are done. 

|| Update: As of 6.8.0, if you upload a new .mo file (i.e. to change translations) you will need to clear the translation cache in uploads/cache by deleting any file with Zend\_Translate in the name.
