+# Architecture
+
+Composable is a [Polkadot parachain](https://wiki.polkadot.network/docs/learn-parachains) built with [Substrate](https://substrate.dev/). We provide a wide variety of DeFi protocols and cross-chain capabilities.
+
+# Overview
+
+The Composable project consists of a blockchain, various utility applications, deployment scripts and setup scripts.
+
+# Runtimes
+
+When building the chain, we use different names to target different [relay chain](https://wiki.polkadot.network/docs/learn-architecture):
+- the **Dali** chain is deployed for **Westend/Rococo/Chachacha**
+- the **Picasso** chain is deployed for **Kusama**
+- the **Composable** chain is deployed for **Polkadot**
+
+The runtimes can be found under the `runtime` directory.
+The chain specs are located in `node/src/chain_spec`.
+
+# Pallets
+
+The building blocks of a substrate blockchain are **pallets**, they define the capability and allow us to implements DeFi protocols.
+You can find them under the `frame` directory. We try to give them a meaningful name.
+
+# Utilities in `utils`
+
+## Price feed server
+
+The `oracle` off-chain worker is fetching prices from a server. We provide a reference implementation named `price-feed` that fetches and caches prices from different, configurable sources.
+
+## Subxt clients
+
+We do our best to maintain generated subxt clients for our runtimes.
+
+# Scripts
+
+The `scripts/polkadot-launch` scripts are setting up a whole Relay + Composable + Basilisk environment.
+Various [polkadotjs](https://polkadot.js.org/docs/) scripts located in `setup` are helping us testing the pallets once the local node is up and running.
