Some things you should know about translating the UI of Tiki:

• Tiki supports any language which may be encoded and displayed using the UTF-8 encoding
• The language directory is here: "lang/"
• Every language has it own subdirectory using ISO-639-1 naming, for example: "lang/en/"
• The base language of Tiki is english (en)
• There are 2 translation resources that contain all translatable Tiki strings:
  • language.php
  • language.js
• The list of translation strings is a php array, where the original string is the key and the translation string is the value
• You can override default translations by using a custom.php file (for example: "lang/en/custom.php")

You have a number of options:

1. Signup with Transifex, translate, download the translation file than upload it to your Tiki from the user interface ( read more here )
2. Use the translation interface on your Tiki: this way you can store your translations in the database so they will not be overwritten when you upgrade your Tiki (read more here LINK)
3. Use a custom.php to store your translations (read more here LINK)
4. Direct translation of language.php via text editor: this migh be overwritten when you upgrade your Tiki, so make a backup before

You can contribute translations via Transifex. It is really easy, no technical knowledge is need, just:
