 # Styx
+
+## Prerequisites
+
+Styx uses a couple of other services to run:
+
+* Kafka for messaging (not implemented yet in the docker, but currently not
+  necessary)
+* Dgraph for graph representation of results
+
+For that purposes, there is a `docker-compose.yml` file that you can spin up
+with the following command when in the directory:
+
+```sh
+docker-compose up -d
+```
+
+*Note*: for some reasons, OpenVPN blocks the establishment of the docker
+compose, you can alternatively run Dgraph manually as such:
+
+```sh
+docker run --rm -it -p 8080:8080 -p 9080:9080 -p 8000:8000 -v ~/dgraph:/dgraph dgraph/standalone:v20.03.0
+```
+
 ## Install
 
 ```sh
 go get -u gitlab.dcso.lolcat/LABS/styx
 cd $GOPATH/src/gitlab.dcso.lolcat/LABS/styx
 go build
+docker-compose up -d # or the other command if you're connected with OpenVPN
 ./styx
 ```
