 ### Tooling
 
+- [Getting Started Script](https://github.com/paritytech/polkadot-sdk/blob/master/scripts/getting-started.sh)
+
+	This script installs all the prerequisites required to start development with the Polkadot SDK.
+
+	You can execute the script in one line like so:
+
+	```sh
+	curl --proto '=https' --tlsv1.2 https://raw.githubusercontent.com/paritytech/polkadot-sdk/master/scripts/getting-started.sh -sSf | sh
+	```
+
 - [The Polkadot SDK](https://github.com/paritytech/polkadot-sdk)
 
 	All development in Polkadot basically revolves around the Polkadot SDK. This project is composed of sub-projects: Substrate, Polkadot, Cumulus. The Polkadot SDK includes useful binaries for doing development.

 ## What is Polkadot?
 
+- Polkadot is a scaling solution for Web3 applications.
+- Polkadot scales through data and execution sharding, allowing for parallelized throughput.
+- Polkadot provides shared security and interoperability to services build on it.
+- Polkadot creates abundant, flexible, and high quality blockspace.
+- Polkadot uses a novel "cynical" rollup to provide fast finality while using minimal resources.
+
 ## Why choose Polkadot?
 
+- On average, blocks are finalized in under 30 seconds.
+	- Compare that to optimisic rollups which may take up to a week!
+- Executing and scaling on standard "gaming" hardware.
+	- Compared to expensive and centralized machines needed for vertical scaling or ZK.
+- 50+ active roll-ups building
+- Billions of dollars of economic security provided to itself and applications running on it.
+
 ## What can you do on Polkadot?
 
+- Build applications which execute automatically (without initial user input).
+- Build applications with full control over block construction and transaction execution.
+- Build applications which dynamically scale up and down execution cores.
+- Build applications which execute at sub-second
+- Build applications where end-users pay no transaction fees.
+
 ## Where is Polkadot leading?
+
+- Among the highest Nakamoto coefficients in the blockchain ecosystem. [[Source][1]]
+- 2nd largest developer community
