+A mini utility to convert [Elasticsearch's REST spec](https://github.com/elastic/elasticsearch/blob/master/rest-api-spec) to Console's (Kibana) autocomplete format.
+
+
+It is used to semi-manually update Console's autocompletion rules.
+
+
+
+### Retrieving the spec
+```
+cd es-spec
+git init
+git remote add origin https://github.com/elastic/elasticsearch
+git config core.sparsecheckout true
+echo "rest-api-spec/src/main/resources/rest-api-spec/api/*" > .git/info/sparse-checkout
+git pull --depth=1 origin master
+```
+
+### Usage
+```
+yarn spec_to_console \
+  -g "es-spec/rest-api-spec/src/main/resources/rest-api-spec/api/*.json" \
+  -d "../kibana/src/core_plugins/console/api_server/spec/generated"
+```
+
+### Information used in Console that is not available in the REST spec
+* Request bodies
+* Data fetched at runtime: indices, fields, snapshots, etc
+* Ad hoc additions
