+[INTERNAL ONLY] Checking how Quesma MVP works with provided Kibana dashboards
+======================================================================
+
+:warning: **This is an internal-only document.** Despite our open-source DNA, procedures described here cannot be replayed 
+without access to internal resources.
+
+
+Let's say someone provided you with some Kibana dashboards exported as NDJSON files.
+
+1. Place dashboard json files in `bin/unjson-dashboards/dashboards`
+2. Run `local-dev-chrome.yml` docker compose file from `quesma-examples` repository (private repo)
+3. Open `bin/unjson-dashboards/main.go` in your IDE \
+   We will be running steps by changing `if` statement condition in that file and running go program.  
+
+There are 4 stages there:
+* `extractMappings()` - figures out indices/mappings from the dashboards and writes them to `bin/unjson-dashboards/mappings` directory
+* `ingestAll()` - generates some test data according to the mappings and ingests it using Elasticsearch API to ClickHouse via Quesma  
+* `createDataViews()/importDashboards()` - creates relevant data views in Kibana
+* `visitDashboards()` - opens headless chrome which makes screenshot of these dashboards, saves them in `bin/unjson-dashboards/screenshots` and adds `index.html` so that these can be browsed in a convenient manner.
