-* Node.js LTS (version 16.13.0 or higher)

   * we generally support the latest LTS release: use [nvm](https://github.com/nvm-sh/nvm) to keep your local system up-to-date
 * Yarn (`npm install -g yarn`)
-* gcc-10 or newer, or a compiler with `__has_builtin()`
+* gcc >=10, clang >=10, or another compiler with `__has_builtin()`
 
 Any version of Yarn will do: the `.yarnrc` file should ensure that all

 # Orchestration
 
+Build feature-rich applications that can orchestrate assets and services across the interchain.
 
-Interface for Cosmos Interchain Accounts [(ICS-27)](https://github.com/cosmos/ibc/blob/main/spec/app/ics-027-interchain-accounts/README.md).
+Usage examples can be found under [src/examples](https://github.com/Agoric/agoric-sdk/tree/master/packages/orchestration/src/examples). They are exported for integration testing with other packages.
