+# Prow Jobs in etcd
+
+## 1. Introduction to Prow
+- https://github.com/kubernetes-sigs/prow
+
+Could you please show me how this is able to run? https://prow.k8s.io/job-history/gs/kubernetes-ci-logs/pr-logs/directory/pull-etcd-e2e-amd64?buildId= How do you trigger a job to run?
+
+
+
+The configuration of etcd is here.
+There are some job types -> Presubmits is the job that is triggered during PR review.
+Here is the presubmits jobs of etcd: https://github.com/kubernetes/test-infra/blob/master/config/jobs/etcd/etcd-presubmits.yaml
+And the job you shared (pull-etcd-e2e-amd64 ) is one of them.
+These tests can be triggered when you leave a comment, like /ok-to-test or /retest, in PR (example)
+You can find all supported commands here.

+## 2. How Prow is used for etcd Testing
+### where the jobs are located, i.e., test-infra repository, in the config/jobs/etcd directory
+The CI of etcd is managed by kubernetes/test-infra, which leverages prow inside it.
