 1. Prepare the blockchain executables
 
-We need two executables - one for Polkadot relay chain, and one for Cumulus based parachain.
+We need several executables - `polkadot`, `polkadot-prepare-worker` and `polkadot-execute-worker`
+for Polkadot relay chain, and `polkadot-parachain` for Cumulus based parachain.
 It is recommended to use released versions of those (as opposed to code from `master`)
 
-**Note:** The 1.0 release of Polkadot has NOT been tested yet.

-For example, to download a `v0.9.38` release of `polkadot` and a corresponding version of a parachain:

+Decide, where to put the binaries (replace `<bin_path>` with it, for all examples) and add it to `PATH`,
+so that `zombienet` will be able to find them:
 ```bash
-wget https://github.com/paritytech/polkadot/releases/download/v0.9.38/polkadot
-wget https://github.com/paritytech/cumulus/releases/download/v0.9.380/polkadot-parachain
-chmod +x ./polkadot*
+export PATH="<bin_path>:$PATH"
 ```
