+
+Try ScanCode Toolkit
+--------------------
+
+This section is about using the Scancode-Toolkit, i.e. Performing a scan on a codebase/files to
+determine their license, copyrights and other information, according to your requirements.
+
+#. The :ref:` newcomer_scan_codebase` section helps you with configuring your virtual environment,
+   installing Scancode and performing a basic scan, and subsequently visualize the results.
+
+#. The :ref:`newcomer_use_scancode_better` section helps you customize the scan according to your
+   requirements, and better understand the advanced features you can use.
 
-.. _newcomer_start_using_scancode:
+#. The :ref:`newcomer_all_tutorials` is essentially an exhaustive list of all Tutorials and How To's
+   with a brief description on what they help you to achieve.
 
-Start Using ScanCode Toolkit
-----------------------------
+.. _newcomer_before:
+
+Before you start using Scancode
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+#. You need to make sure :ref:`install_prerequisites` are installed, and a `virtualenv <https://docs.python-guide.org/dev/virtualenvs/>`_
+   is created.
+
+#. Now you can either run ``pip install scancode-toolkit`` like that in the
+   :ref:`pip_install` documentation, or follow the instructions for the
+   :ref:`latest_release_download_install` method. Alternatively, you can also
+   :ref:`source_configure_install`.
+
+#. Run ``scancode -h`` to make sure Scancode was installed properly.
+   If this shows any Error, refer the `Common Installation Errors Issue <https://github.com/nexB/scancode-toolkit/issues/1837>`_
+   for common errors. The documentation also has tips on :ref:`ide_config`.
+
+.. note::
+
+    Refer :ref:`synopsis_quickstart` to make sure you are using the scan command correctly.
 
 .. _newcomer_scan_codebase:
 
 Scan a Codebase
 ^^^^^^^^^^^^^^^
 
+Once you are all set up with Scancode Toolkit, i.e. Running ``scancode -h`` shows the
+:ref:`cli_help_text`, you can start scanning files or a codebase.
+
+#. Refer :ref:`synopsis_quickstart` for commonly used scan commands, and commonly used
+   :ref:`synopsis_output`. (The recommended output format is ``JSON``)
+
+#. Refer `this section <file:///home/ayansm/Desktop/GSoD/main_repo/aboutcode/docs/build/html/scancode-toolkit/cli-reference/list-options.html#all-extractcode-options>`_ for Extractcode Options.
+
+#. :ref:`how_to_run_a_scan` is a sample tutorial for absolute beginners, to walk them through the
+   process of running a scan. Follow this tutorial and perform a scan on the ``sample`` folder
+   distributed with ScanCode, or any file/folder of your choice. Avoid advanced options, and just
+   follow the basic instructions.
+
+#. ScanCode generates output files with scan results. You can visualize ``JSON`` result files using
+   `Scancode Workbench <https://github.com/nexB/scancode-workbench>`_. Follow this tutorial :ref:`how_to_visualize_scan_results`
+   to visualize the scan results.
+
 .. _newcomer_use_scancode_better:

+Now this section has three types of pages:
+
+#. The :ref:`cli_synopsis` page and the :ref:`how_to_run_a_scan` page as summaries.
+#. An exhaustive list of all Command Line Options at :ref:`cli_list_options`
+#. All the other pages detailing the :ref:`scancode_cli_options`
+
+Note that the page for one type of options also has a short list of all the options detailed on
+that page in the beginning. The :ref:`cli_list_options` page just has all of them together, and
+also the extractcode options.
