+CC applications such as CC Search and the CC License Chooser are used by
+millions of users worldwide. Translating these services into the languages our
+users speak and read is integral to making these services accessible to our
+diverse user base.
+
+We use Transifex to manage our translation files. It provides an intuitive UI
+and many useful tools. Let's see how you can join us there and get started.
+
+## For translators

+    translate.

+    remain to be translated. Here onwards you have three paths for translating
+    the site.
+    - Transifex editor UI, by clicking the 'Translate' button
+    - Transifex live UI, by clicking the 'Live' button
+    - Local string translation, by clicking the download and upload buttons

+
+* * **Method 1: Translating using the Transifex editor UI**
+    * To do this, click on the 'Translate' button from the resource modal. You
+      will be taken to a list of all the strings from the website.
+    * Switch the language to your target language using the menu bar on the
+      upper side of the screen.
+    * Click on any string, enter the translation in the lower box and click
+      the 'Save Translation' button to commit the change.
+    * Some text has HTML tags in it. In those cases you can click on the tags in
+      the source text to copy them over in the translated text. You can also
+      drag to move them around as needed.

+      their counterparts in your language by clicking the 'Download file to
+      translate' button.
+    * For the untranslated strings, both key and value will be the same.
+      ```json
+      { "Hello, World!": "Hello, World!" }
+      ```
+    * Change the JSON values to the translated text.
+      ```json
+      { "Hello World": "नमस्ते, दुनिया!" }
+      ```
+    * Upload the translated JSON file using the 'Upload file' button.
+
+Your translations will go live as soon as they are approved by the admins.
