In this repository, `escrow_pallet` is installed twofold:

+To use a full node you will have to initialize the repository as a git submodule first:
+```
+git submodule init
+git submodule update
+```
-Run either of them with `bash run-node-tiny.sh` or `bash run-node-full.sh`.
+Run either a tiny or full node with `bash run-node-tiny.sh` or `bash run-node-full.sh`.
