+How to generate documentation
+=============================
+
+
+Requirements
+------------
+
+This tool uses Sphinx and read-the-doc theme. All required modules are listed in
+src/requirements.txt. These requirements are addition to CSIT requirements
+defined in requirements.txt.
+
+The generated documentation needs Java script to be fully functional.
+
+The generated documentation is in the directory _build.
+
+
+How to generate documentation
+-----------------------------
+
+ - pull the last changes from git
+ - run: ./run_doc.sh
+
+
+What is documented
+------------------
+
+All modules which are in these directories are documented:
+ - resources/libraries/python
+ - resources/libraries/robot
+ - tests
+
+If you add / remove / rename a module or directory to one of these
+directories, nothing is needed to be done.
+
+
+How to add or change info in generated documentation
+----------------------------------------------------
+
+There are templates for
+ - index
+ - Python library documentation
+ - Robot library documentation
+ - Functional tests documentation
+ - Performance tests documenation
+in src/ directory.
+
+You can add information you want at the beginning of the file, generated
+documentation will be appended at the end of these files.
+
+See index.rst for example. The information there was copy&pasted from fd.io
+
+
+How to document code for perfect results
+----------------------------------------
+
+Follow PEP8 and guidelines on wiki https://wiki.fd.io/view/CSIT/Documentation
+
+This is the best practice when we use Sphinx:
+
+Python code
++++++++++++
+
+.. code:: python
+
+    """Module description, start with one-short-sentence-description.
+
+    Add more descriptive text.
+
+    You can add a list (there must be an empty line):
+
+    - item,
+    - second item.
+
+    or numbered list (there also must be an empty line):
+
+    #. The first item,
+    #. The second item.
+
+    """
+
+    class ExampleClass(BaseClass):
+        """Start with one-short-sentence-description.
+
+        Add more descriptive text.
+        """
+
+        def example_function(parameter, param_def="def"):
+            """Start with one-short-sentence-description.
+
+            Add more descriptive text, and / or example.
+
+            :Example:
+
+            followed by a blank line!
+
+            You can use also:
+            .. seealso:: blabla
+            .. warnings:: blabla
+            .. note:: blabla
+            .. todo:: blabla
+
+            :param parameter: The first parameter. Capital letter at the
+            beginning, full stop at the end, 80 characters long lines.
+            :param param_def: The parameter with default value.
+            :type param: str, int, dict, ... Use python data types.
+            :type param_def: str
+            :raises: ValueError - describe when this exception is raised.
+            :returns: Nice string.
+            :rtype: str
+            """
