 ## Deploy process
 
-They are deployed with the `ci/testnet-deploy.sh` script. There is a scheduled buildkite job which runs to do the deploy,
-look at `testnet-deploy` to see the agent which ran it and the logs. There is also a manual job to do the deploy manually..
-Validators are selected based on their machine name and everyone gets the binaries installed from snap.
+They are deployed with the `ci/testnet-manager.sh` script through a list of [scheduled
+buildkite jobs](https://buildkite.com/solana-labs/testnet-management/settings/schedules).
+Each testnet can be manually manipulated from buildkite as well.  The `-perf`
+testnets use a release tarball while the non`-perf` builds use the snap build
+(we've observed that the snap build runs slower than a tarball but this has yet
+to be root caused).
