# Run a Cosmovisor

**`cosmovisor`** is a small process manager for Cosmos SDK application binaries that monitors the governance module for incoming chain upgrade proposals. If it sees a proposal that gets approved, **`cosmovisor`** can automatically download the new binary, stop the current binary, switch from the old binary to the new one, and finally restart the node with the new binary.
