+How to use the web4 cli
+=======================
 
 ## Example usage
 
-1. Navigate into a directory where @iov/keycontrol is installed
-   (e.g `cd web4 && yarn install && yarn build`)
-2. Run `node` in interactive mode
+1. Build all dependencies: `cd web4 && yarn install && yarn build`
+2. Go to `packages/iov-cli`, run `yarn web4` and follow on-screen instructions
 3. Play around like in the following example code:
 
 ```
-> const { Ed25519SimpleAddressKeyringEntry, Keyring, UserProfile } = require("@iov/keycontrol")
 > const profile = new UserProfile();
 > profile.addEntry(Ed25519SimpleAddressKeyringEntry.fromMnemonic("melt wisdom mesh wash item catalog talk enjoy gaze hat brush wash"))
