+### Local CCS (cross cluster search) instructions
+* Spin up a "remote" instance of Elasticsearch (this needs to start before the "local" instance for some odd reason):
+```
+yarn es snapshot -E http.port=9500 -E transport.port=9600 -E path.data=../remote
+```
+
+* Spin up the "local" instance of Elasticsearch:
+```
+yarn es snapshot
+```
+
+* Load data into both the "remote" and "local" clusters:
+```
+node scripts/makelogs.js -c 100000 -d 100/10 --url elastic:changeme@localhost:9500
+node scripts/makelogs.js -c 100000 -d 100/10 --url elastic:changeme@localhost:9200
+```
+
+* Spin up Kibana:
+```
+yarn start
+```
+
+Once it is running, do the following:
+* Open http://localhost:5601/app/management/data/remote_clusters
+* Click "Add a remote cluster"
+* Choose a name, put "localhost:9600" for "Seed nodes", and save (check "Yes, I have setup trust")
+* Make sure the connection status is "Connected"
+* Open http://localhost:5601/app/management/kibana/dataViews
+* Click "Create data view"
+* For "Index pattern", put "logstash-\*,\*:logstash-\*" (the asterisk indicates all remote clusters) and save
+* Go to Discover and select your data view, and it should be querying using CCS
