+# Log CLI usage Instructions
+
+Loki's main UI is Grafana; however, a basic CLI is provided as a proof of concept.
+
+Once you have Loki running in a cluster, you can query logs from that cluster using the following commands:
+
+```
+$ go get github.com/grafana/loki/cmd/logcli
+$ export GRAFANA_ADDR=https://logs-us-west1.grafana.net
+$ export GRAFANA_USERNAME=<username>
+$ export GRAFANA_PASSWORD=<password>
+$ logcli labels job
+https://logs-dev-ops-tools1.grafana.net/api/prom/label/job/values
+cortex-ops/consul
+cortex-ops/cortex-gw
+...
+$ logcli query '{job="cortex-ops/consul"}'
+https://logs-dev-ops-tools1.grafana.net/api/prom/query?query=%7Bjob%3D%22cortex-ops%2Fconsul%22%7D&limit=30&start=1529928228&end=1529931828&direction=backward&regexp=
