 Installation
 ============
 
-Pre-requisites:
+There are 3 main ways you can `install ScanCode <https://scancode-toolkit.readthedocs.io/en/latest/getting-started/install.html>`_.
+
+- Installation as an Application: Downloading Releases (Recommended)
+- Installation as a library: via pip
+- Installation from Source Code: Git Clone
+
+Prerequisites
+-------------
+
+Before installing ScanCode make sure you've installed the prerequisites properly. This mainly
+refers to installing the required Python interpreter (Python 3.6 is recommended).
+
+- For Linux(Ubuntu): ``sudo apt install python3.6-dev bzip2 xz-utils zlib1g libxml2-dev libxslt1-dev``
+- For MacOS: Install Python 3.6.8 from https://www.python.org/ftp/python/3.6.8/python-3.6.8-macosx10.6.pkg
+- For Windows: Install Python 3.6.8 from https://www.python.org/ftp/python/3.6.8/python-3.6.8.exe
+
+Refer `Prerequisites <https://scancode-toolkit.readthedocs.io/en/latest/getting-started/install.html#prerequisites>`_ for detailed information on all different platforms and Python Versions.
+
+Installation as an Application : Downloading Releases
+-----------------------------------------------------
 
-* On Windows, please follow the `Comprehensive Installation instructions
-  <https://github.com/nexB/scancode-toolkit/wiki/Comprehensive-Installation>`_.
-  Make sure you use Python 2.7 32 bits from
-  https://www.python.org/ftp/python/2.7.15/python-2.7.15.msi
+#. Download and extract the latest ScanCode release from https://github.com/nexB/scancode-toolkit/releases/
 
-* On macOS, install Python 2.7 from
-  https://www.python.org/ftp/python/2.7.15/python-2.7.15-macosx10.6.pkg
+#. Open a terminal window and then `cd` to the extracted ScanCode directory. 
 
-  Next, download and extract the latest ScanCode release from
-  https://github.com/nexB/scancode-toolkit/releases/
+#. Run this command to self-configure and display the help-text.
 
-* On Linux install the Python 2.7 "devel" and these packages using your
-  distribution package manager:
+    - Linux/Mac : ``./scancode --help``
+    - Windows : ``scancode --help``
 
-  * On Ubuntu 14, 16 and 18 use:
-    ``sudo apt-get install python-dev xz-utils zlib1g libxml2-dev libxslt1-dev bzip2``
+Installation as a library: via pip
+----------------------------------
 
-  * On Debian and Debian-based distros use:
-    ``sudo apt-get install python-dev xz-utils zlib1g libxml2-dev libxslt1-dev libbz2-1.0``
+#. Create a Python 3.6 Virtual Environment and activate the same::
 
-  * On RPM distros use:
-    ``sudo yum install python-devel xz-libs zlib libxml2-devel libxslt-devel bzip2-libs``
+    virtualenv -p /usr/bin/python3.6 venv-scancode && source venv-scancode/bin/activate
 
-  * On Fedora 22 and later use:
-    ``sudo dnf install python-devel xz-libs zlib libxml2-devel libxslt-devel bzip2-libs``
+#. Run ``pip install scancode-toolkit``

-  for additional instructions.
+Installation from Source Code: Git Clone
+----------------------------------------
 
+#. Download the Source Code or Use Git Clone::
 
-Next, download and extract the latest ScanCode release from
-https://github.com/nexB/scancode-toolkit/releases/
+    git clone https://github.com/nexB/scancode-toolkit.git
+    cd scancode-toolkit
 
+#. You can jump to any checkpoint/Branch/Commit using the following command::
 
-Open a terminal window and then `cd` to the extracted ScanCode directory and run
-this command to display help. ScanCode will self-configure if needed::
