 # XTM Integration
 
 The integration with the XTM API can be run using the following command:
 
     python -m cms.bin.xtm_translations [-h] [-v] {login,create,upload,download}
 
 
 and it has four main operational modes:
 
 
-## 1. XTM Login 
+## 1. XTM Login
 
-This mode prompts the user for the login credentials and prompts

+This mode prompts the user for the login credentials and prompts
+the API for the authentication token. This token should then be saved as an
 environment variable to be used in the other modes. It can be run as follows:
 
 
     python -m cms.bin.xtm_translations [-h] [-v] login [-h]
 
 
 
 ## 2. Project Creation
 
 In this mode, one can create an XTM project. It can be run as follows:
 
 
-    python -m cms.bin.xtm_translations [-h] [-v] create [-h] --name NAME 
-                --desc DESC --client-id CLIENT_ID --ref-id REF_ID 
-                --workflow-id WORKFLOW_ID [--source-lang SOURCE_LANG] 
+    python -m cms.bin.xtm_translations [-h] [-v] create [-h] --name NAME
+                --desc DESC --client-id CLIENT_ID --ref-id REF_ID
+                --workflow-id WORKFLOW_ID [--source-lang SOURCE_LANG]
                 [--save-id] [source_dir]
 
 
 where:
 * --name* = The name of the project will have once created.
 * *--desc** = The description you wish to add to the project.
-* *--client-id** = The id of the **pre-configured** XTM client you want 
+* *--client-id** = The id of the **pre-configured** XTM client you want
 associated with the project. Has to be an integer!
 * *--ref-id** = The reference id you want associated with the XTM project.
-* *--workflow-id** = The id of the **pre-configured** XTM workflow to be

 associated with the project. Has to be an integer!
-* *--source-lang* = The language of the source files. If not provided,

 'settings.ini' or not.

+to be uploaded on project creation. It will also be used to automatically
 detect the target languages for this specific project.
 
 **Note:** All arguments marked with * are **mandatory** and the script will
 fail if not provided.
 
 In order for this mode to work, it requires the XTM authentication token
 to be saved in the `XTM_TOKEN` environment variable.
 
 
 ## 3. File Uploading
 
 This mode can be used to upload new files for translation to an existing project.
 It can be run as follows:
 
 
-    python -m cms.bin.xtm_translations [-h] [-v] upload [-h] [--no-overwrite] 
+    python -m cms.bin.xtm_translations [-h] [-v] upload [-h] [--no-overwrite]
                 [source_dir]
 
 
 where:
-* *--no-overwrite* = If this flag is set, then the script would **create new 
+* *--no-overwrite* = If this flag is set, then the script would **create new
 files** in XTM, instead of overwriting the ones that were already there.
 * *source_dir* = The source directory of the website. See above for the full
 explanation.

+If you wish to add a new target language to the project automatically,
 simply create a corresponding directory in the website's `locales` directory
 and the script will update the XTM project accordingly before uploading the
 new files and will create jobs for the new languages as well.
 
 In order for this mode to work, it requires two things to be present:
 1. The XTM authentication token saved in the `XTM_TOKEN` environment variable.
-2. The XTM project number present in `settings.ini`, under the `project_id` 
+2. The XTM project number present in `settings.ini`, under the `project_id`
 option, in the `XTM` section.
 
 
 ## 4. Translation Files Downloading
 
 This mode downloads the translation files from the XTM project and saves them
 in the website's `locales` directory. It can be run as follows:
 
     python -m cms.bin.xtm_translations [-h] [-v] download [-h] [source_dir]
 
 
 where `source_dir` is the source directory of the website. See above for full
 explanation.
 
 When run in this mode, the script will remove all the translation files that
 were previously saved locally and then save the new ones in their place.
 
 In order for this mode to work, three requirements need to be fulfilled:
 1. The XTM authentication token saved in the `XTM_TOKEN` environment variable.
-2. The XTM project number present in `settings.ini`, under the `project_id` 
+2. The XTM project number present in `settings.ini`, under the `project_id`
 option, in the `XTM` section.
 3. (At least one) translation file(s) to be present in XTM.
