 ### Creating an annotation task
 
-1.  Create an annotation task pressing ``Create New Task`` button on the main page.
-
-    ![](static/documentation/images/image004.jpg)
-
-1.  Specify mandatory parameters of the task.
-    You have to fill in ``Name``, ``Labels`` and press the ``Select Files`` button.
-    After that you have to choose data you want to annotate.
-
-    ![](static/documentation/images/image005.jpg)
-
-    **Labels**. Use the following layout to create labels:
-    ``label_name <prefix>input_type=attribute_name:attribute_value1,attribute_value2``.
-    You can specify multiple labels and attributes and divide them pressing the space button.
-    Attributes belong to a previous label.
-
-    Example:
-    - ``vehicle @select=type:__undefined__,car,truck,bus,train ~radio=quality:good,bad ~checkbox=parked:false`` -
-    one label with multiple attributes
-    - ``car person bike`` - three labels without attributes
-    - ``circle @radio=color:green,red,blue @number=radius:0,10,0.1 line square`` -
-    one label with two attributes and two labels without attributes
+1.  Create an annotation task pressing ``Create new task`` button on the main page.
+![](static/documentation/images/image004.jpg)
 
-    ``label_name``: for example _vehicle, person, face etc._
+1.  Specify parameters of the task:
 
-    ``<prefix>``:
-    - Use ``@`` for unique attributes which cannot be changed from frame to frame _(e.g. age, gender, color, etc.)_
-    - Use ``~`` for temporary attributes which can be changed on any frame _(e.g. quality, pose, truncated, etc.)_
+    #### Basic configuration
 
-    ``input_type``: the following input types are available ``select``, ``checkbox``, ``radio``, ``number``, ``text``.
+    **Name** The name of the task to be created.
 
-    ``attribute_name``: for example, _age, quality, parked_
-
-    ``attribute_value``: for example, _middle-age, good, true_
-
-    Default value for an attribute is the first value after "``:``".
-
-    For ``select`` and ``radio`` input types the special value is available: ``__undefined__``.
-    Specify this value first if an attribute should be annotated explicitly.
-
-    **Bug Tracker**. Specify full bug tracker's URL if you have it.
-
-    **Dataset Repository**.  URL link of the repository optionally specifies the path to the repository for storage
-    (``default: annotation / <dump_file_name> .zip``).
-    The .zip and .xml file extension of annotation are supported.
-    Field format: ``URL [PATH]`` example: ``https://github.com/project/repos.git  [1/2/3/4/annotation.xml]``
+    ![](static/documentation/images/image005.jpg)
 
-    Supported URL formats :
-    - ``https://github.com/project/repos[.git]``
-    - ``github.com/project/repos[.git]``
-    - ``[email protected]:project/repos[.git]``
+    **Labels**. There are two ways of working with labels:
+    -   The ``Constructor`` is a simple way to add and adjust labels. To add a new label click the ``Add label`` button.
+          ![](static/documentation/images/image123.jpg)
+
+        You can set a name of the label in the ``Label name`` field.
+
+          ![](static/documentation/images/image124.jpg)
+
+        If necessary you can add an attribute and set its properties by clicking ``Add an attribute``:
+
+          ![](static/documentation/images/image125.jpg)
+
+        The following actions are available here: 
+        1. Set the attribute’s name. 
+        1. Choose the way to display the attribute: 
+           - Select — drop down list of value 
+           - Radio — is used when it is necessary to choose just one option out of few suggested. 
+           - Checkbox — is used when it is necessary to choose any number of options out of suggested. 
+           - Text — is used when an attribute is entered as a text. 
+           - Number — is used when an attribute is entered as a number. 
+        1. Set values for the attribute. The values could be separated by pressing ``Enter``. 
+        The entered value is displayed as a separate element which could be deleted 
+        by pressing ``Backspace`` or clicking the close button (x). 
+        If the specified way of displaying the attribute is Text or Number, 
+        the entered value will be displayed as text by default (e.g. you can specify the text format).
+        1. Checkbox ``Mutable`` determines if an attribute would be changed frame to frame. 
+        1. You can delete the attribute by clicking the close button (x).
+
+        Click the ``Continue`` button to add more labels. 
+        If you need to cancel adding a label - press the ``Cancel`` button. 
+        After all the necessary labels are added click the ``Done`` button.  
+        After clicking ``Done`` the added labels would be displayed as separate elements of different colour. 
+        You can edit or delete labels by clicking ``Update attributes`` or ``Delete label``. 
+
+    -   The ``Raw`` is a way of working with labels for an advanced user. 
+    Raw presents label data in _json_ format with an option of editing and copying labels as a text. 
+    The ``Done`` button applies the changes and the ``Reset`` button cancels the changes.

-    **Use LFS**. If the annotation file is large, you can create a repository with
-    [LFS](https://git-lfs.github.com/) support.
-
-    **Source**. Choose "Local" if you want to use files from your PC.
-    Choose the "Remote" option if you want to use a one url-adress or a list.
-    To create huge tasks please use shared server directory (choose "Share").
