+# Enterprise Search Functional E2E Tests
+
+## Running these tests
+
+Follow the [Functional Test Runner instructions](https://www.elastic.co/guide/en/kibana/current/development-functional-tests.html#_running_functional_tests).
+
+There are two suites available to run, a suite that requires a Kibana instance without an `enterpriseSearch.host`
+configured, and one that does. The later also [requires a running Enterprise Search instance](#enterprise-search-requirement), and a Private API key
+from that instance set in an Environment variable.
+
+Ex.
+
+```sh
+# Run specs from the x-pack directory
+cd x-pack
+
+# Run tests that require enterpriseSearch.host variable
+APP_SEARCH_API_KEY=[use private key from local App Search instance here] node scripts/functional_tests --config test/functional_enterprise_search/with_host_configured.config.ts
+
+# Run tests that do not require enterpriseSearch.host variable
+APP_SEARCH_API_KEY=[use private key from local App Search instance here] node scripts/functional_tests --config test/functional_enterprise_search/without_host_configured.config.ts
+```
+
+## Enterprise Search Requirement
+
+These tests will not currently start an instance of App Search automatically. As such, they are not run as part of CI and are most useful for local regression testing.
+
+The easiest way to start Enterprise Search for these tests is to check out the `ent-search` project
+and use the following script.
+
+```sh
+cd script/stack_scripts
+/start-with-license-and-expiration.sh platinum 500000
+```
+
+Requirements for Enterprise Search:
+
+- Running on port 3002 against a separate Elasticsearch cluster.
+- Elasticsearch must have a platinum or greater level license (or trial).
+- Must have Standard or Native Auth configured with an `enterprise_search` user with password `changeme`.
+- There should be NO existing Engines or Meta Engines.
