 The integration tests depends on a local instance of KERIA, vLEI-Server and Witness Demo. These are specified in the [Docker Compose](./docker-compose.yaml) file. To start the dependencies, use docker compose:
 
 ```bash
-docker compose up deps
+docker compose up --wait
 ```
 
 If successful, it should print someting like this:
 
 ```bash
-$ docker compose up deps

 It is possible to change the keria image by using environment variables. For example, to use weboftrust/keria:0.1.3, do:
 
 ```bash
 export KERIA_IMAGE_TAG=0.1.3
 docker compose pull
-docker compose up deps
+docker compose up --wait
 ```
 
 To use another repository, you can do:
 
 ```bash
 export KERIA_IMAGE=gleif/keria
 docker compose pull
-docker compose up deps
+docker compose up --wait
 ```
 
 **Important!** The integration tests runs on the build output in `dist/` directory. Make sure to run build before running the integration tests.
