 # vSwarm-proto
 
-vSwarm-proto is a utility for [vSwarm](https://github.com/ease-lab/vSwarm/) containing all the proto files and client applications necessary to run benchmarks using [relay](https://github.com/ease-lab/vSwarm/tree/main/tools/relay).

+
+## CLI command
+The `cmd` subfolder contains a command line interface for invoking any kind of function that implement one of the protocols in this repository.
+
+## Releasing new versions
+In order to release a new version do the following:
+1. Increment the version number in `cmd/version.go`.
+2. Build the release with `make release`
+3. Push the new version with `git push <VERSION TAG>`
