+# Rivet Client
+
+## Projects
+
+- **manager** The binary responsible for talking to the Rivet Server. This will spawn a runner based on the flavor (isolate or container).
+- **isolate-v8-runner** Runs actors using V8 isolates.
+- **container-runner** Runs actors as containers.
+- **runner-protocol** Shared types for the runner's protocol.
+- **echo** Used as a test binary for testing pegboard-manager.
+
+## rustls and OpenSSL
+
+We opt to use rustls instead of OpenSSL in all client binaries in the interest of portability.
