+# Introduction to Wormhole
+
+Wormhole is a generic _message-passing protocol_ that enables communication between blockchains.
+
+![Message-passing process in the Wormhole protocol](/images/learn/introduction/simple-overview.webp)
+
+!!! note
+    The above is an oversimplified illustration of the protocol; details about the architecture and components are available on the [architecture page](#){target=\_blank}.
+This simple message-passing protocol allows developers and users of cross-chain applications to leverage the advantages of multiple ecosystems.
+
+## What Isn't Wormhole?
+
+- **Wormhole is _not_ a blockchain** - it provides a means of communication between blockchains or rollups
+
+- **Wormhole is _not_ a token bridge** - however, there are [protocols built on Wormhole](https://portalbridge.com/#/transfer){target=\_blank} that serve this purpose
+
+## What Can Wormhole Be Used For?
+
+Consider the following examples of potential applications enabled by Wormhole:
+
+- **Cross-Chain Exchange** - using [Wormhole Connect](#){target=\_blank}, developers can build exchanges that allow deposits from any Wormhole-connected chain, significantly increasing liquidity access
+- **Cross-Chain Governance** - NFT collections on different networks can use Wormhole to communicate votes cast on their respective chains to a designated "voting" chain for combined proposals
+- **Cross-Chain Game** - games can be developed on a performant network like Solana, with rewards issued as NFTs on another network, such as Ethereum
+
+## Get Started
+
+### Quick Start Tutorials
+
+Tutorials are available to get started quickly and explain the concepts involved.
+
+- **[Quick Start - Off Chain](#){target=\_blank}** - integrate Wormhole Connect into a new or existing web UI
+- **[Quick Start - On Chain](#){target=\_blank}** - send your first cross-chain message
+
+More tutorials are available [on github](#){target=\_blank}. <!-- tutorials will be on the docs site -->
+
+## Explore
+
+Discover more about the Wormhole ecosystem, components, and protocols:
+
+- **[Architecture](#){target=\_blank}** - explore the components of the protocol
+- **[Protocol Specifications](https://github.com/wormhole-foundation/wormhole/tree/main/whitepapers){target=\_blank}** - learn about the protocols built on top of Wormhole
+
+## Demos
+
+Demos offer more realistic implementations than tutorials:
+
+- **[Wormhole Scaffolding](https://github.com/wormhole-foundation/wormhole-scaffolding){target=\_blank}** - quickly set up a project with the Scaffolding repo
+- **[xDapp Book Projects](https://github.com/wormhole-foundation/xdapp-book/tree/main/projects){target=\_blank}** - run and learn from example programs
+
+More demos are available in the [demos page](#){target=\_blank}.
