+# Starting Indy Valdiator
+
+## Starting
+
+### Build and run containers
+
+go to cactus/tools/docker/indy-testnet and 
+
+```
+$ cd cactus/tools/docker/indy-testnet
+$ docker-compose -f ./under-construction-docker-compose.yaml up
+Starting nginx     ... done
+Starting validator ... done
+Starting indy_pool ... done
+```
+
+Type Ctrl + C to stop these containers.
+
+### Verify that containers are actually up
+
+Type following in the host environemnt:
+
+```
+　$ docker ps | grep -e indy_pool -e nginx -e valipy
+```
+Three containers `indy_pool`, `nginx` and `valipy` must be printed.
+
+### Start Indy validator server
+
+Run following commands (from host environment) to log into validator container:
+
+```
+$ sudo docker exec -it validator /bin/bash
+```
+ and run the server using these commands:
+
+```
+$ cd /root/validator
+$ pip install pyyaml
+$ TEST_POOL_IP=172.16.0.2 python -m main
+```
