-CosmWasm is a smart contract platform focusing on security, performance, and interoperability. It is
-the only smart contracting platform for public blockchains with heavy adoption outside of the EVM
-world.
+The [x/wasm module](https://github.com/CosmWasm/wasmd/tree/main/x/wasm), the root of CosmWasm, is a
+[Cosmos SDK](https://docs.cosmos.network/) module enabling smart contracts to execute on the
+[Wasmer](https://wasmer.io/) virtual machine. It is a bridge between Cosmos chain and the
+[WasmVM](https://github.com/CosmWasm/wasmvm) executing the smart contracts. CosmWasm itself is the
+whole ecosystem built around it with a mission to make smart contracts development easy and
+reliable. The focuses of the CosmWasm platform are security, performance, and interoperability.
 
-Here you can find its documentation.
+We chose to target a Rust programming language as a smart contract development stack, as it has the
+best Wasm compiler on the market so far. We do not provide bindings to help write smart contracts in
+another stack that compiles to Wasm, and we don't support that.
+
+Here is where to find CosmWasm in the whole Cosmos stack:

+    "Cosmos SDK" ||--o{ "Custom Module" : Includes
+    "Wasm/WasmVM" ||--o{ "CosmWasm Smart Contract": Executes
+
+```
+
+The important thing about CosmWasm smart contracts is their transparency. Every smart contract
+instance has its unique address on the chain, and it can act just like any other chain client. It is
+easy to implement communication between two smart contracts on the same chain. CosmWasm standard
+library provides simple utilities to communicate with non-CosmWasm modules on the chain. That
+includes common Cosmos modules like bank or staking and any custom module unique for a particular
+chain. Finally, CosmWasm is built around the [IBC](https://www.ibcprotocol.dev/) and provides a
+simple API to communicate with other chains and contracts using IBC-based protocols
+
+This documentation already covers most of the stack. Still, some parts are a work in progress. If
+there is something you remember being here in the old documentation, you can find its content at
+https://github.com/CosmWasm/docs-deprecated. Remember that the old documentation is deprecated,
+mostly outdated, and will not be maintained. We would appreciate any GitHub issues about missing
+parts in the [documentation repository](https://github.com/CosmWasm/docs).
+
+It is worth noting about additional CosmWasm learning resources:
