 ## Plan, Install and Configure Sunbird 
-The deployment of Sunbird in a live environment requires several distributed components. Before you start installation, check for the following components:
-
-### Size and Verify your Environment
-
-Requirements for Sunbird installation depends on the environment on which you install and use Sunbird. 
-For details, check the **Prerequisites** section for your chosen installation method. 
-
-For example; if you choose to do a medium-scale deployment of Sunbird, check [here](http://www.sunbird.org/developer-docs/installation/medium_scale_deploy/#pre-requisites){:target="_blank"} 
-
-### Choosing an Installation method
-
-Based on your usage and the level of complexity which you are comfortable with, choose from among the different options available for installing and running Sunbird.
-
-### Pre-requisites
-
-If you install Sunbird in any environment or choose any method of installation, the basic minimum prerequisites are: 
-
-   - Use of a Linux OS flavor (developer installation is possible on MacOS)
-   - Comfort with use of a terminal as Sunbird installation is triggered from a command-line terminal
-
-***Note: The prerequisites are not necessary to try the sandbox option***

-## Installation options
+The deployment of Sunbird in a live environment requires several distributed components. Before you start installation, please understand the following possibilities:
 
 ### Try Sunbird
 
-If you are looking to experiment with Sunbird and test its feature set, we recommend you use the [Sunbird sandbox](https://staging.open-sunbird.org/){:target="_blank"} which is running in the cloud. 
+If you are looking to experiment with Sunbird and test its feature set, we recommend you use the [Sunbird sandbox](https://staging.open-sunbird.org/){:target="_blank"} which is hosted in the cloud. 
 
 **Note: Data created in the sandbox is erased after 24 hours**
 
 ### Extend Sunbird
 
-If you plan to modify and contribute code to the Sunbird project, we recommend you [Install Sunbird on your machine](developer-docs/installation/installing_sunbirdon_machine/){:target="_blank"}. This allows you to get started quickly and help extend Sunbird.
-
-### Deploy Sunbird for up to 10 Thousand Users
+If you plan to modify and contribute code to the Sunbird project, we recommend you [Developer Installation](developer-docs/installation/developer_installation/){:target="_blank"}. This allows you to get started quickly and help extend the Sunbird.
 
-If you plan to run Sunbird for up to 10 thousand users, we recommend you follow the [Medium scale deployment](developer-docs/installation/medium_scale_deploy/){:target="_blank"} process. This option uses fewer resources to run Sunbird and has some limits on how much the installed application can scale.
+### Deploy Sunbird for your users
 
-### Deploy Sunbird for over 10 Thousand Users 
+If you plan to install Sunbird for your users, we recommend you follow the [Server Installation](developer-docs/installation/medium_scale_deploy/){:target="_blank"} process.
 
-You can plan to run Sunbird in a setting with over 10 thousand users. This will deploy Sunbird to a cloud-hosting provider of your choice in a fully containerized manner. The containers allow you to scale the resources Sunbird consumes based on the usage.
