 ## Prerequisite
 
-* Make sure you have installed Docker with `docker-compose` (version > `1.25.0`). On Windows, this can be Docker Desktop with WSL 2 integration.

 * In case you also build the worker directly, without docker (e.g. on a dev machine, running `make`), you should run `make clean` before running the docker build. Otherwise, it can occasionally lead to build errors.
 * The node image version that is loaded in the `docker-compose.yml`, (e.g. `image: "integritee/integritee-node-dev:1.0.11"`) needs to be compatible with the worker you're trying to build.

 ## Running the docker setup
