+## Feature flags
+
+To set up a flagged feature, add the name of the feature key (`apm:myFeature`) to [commmon/ui_settings_keys.ts](./common/ui_settings_keys.ts) and the feature parameters to [server/ui_settings.ts](./server/ui_settings.ts).
+
+Test for the feature like:
+
+```js
+import { myFeatureEnabled } from '../ui_settings_keys';
+if (core.uiSettings.get(myFeatureEnabled)) {
+  doStuff();
+}
+```
+
+Settings can be managed in Kibana under Stack Management > Advanced Settings > Observability.

+## Local environment setup
+
+### Kibana
+
+```
+git clone [email protected]:elastic/kibana.git
+cd kibana/
+yarn kbn bootstrap
+yarn start --no-base-path
+```
+
+### APM Server, Elasticsearch and data
+
+To access an elasticsearch instance that has live data you have two options:
+
+#### A. Connect to Elasticsearch on Cloud (internal devs only)
+
+Find the credentials for the cluster [here](https://github.com/elastic/apm-dev/blob/master/docs/credentials/apm-ui-clusters.md#apmelstcco)
+
+#### B. Start Elastic Stack and APM data generators
+
+```
+git clone [email protected]:elastic/apm-integration-testing.git
+cd apm-integration-testing/
+./scripts/compose.py start master --all --no-kibana
+```
+
+_Docker Compose is required_
+
+### Setup default APM users
+
+APM behaves differently depending on which the role and permissions a logged in user has. To create the users run:
+
+```sh
+node x-pack/plugins/apm/scripts/create-apm-users-and-roles.js --username admin --password changeme --kibana-url http://localhost:5601 --role-suffix <github-username-or-something-unique>
+```
+
+This will create:
+
+**apm_read_user**: Read only user
+
+**apm_power_user**: Read+write user.
+
+## Debugging Elasticsearch queries
+
+All APM api endpoints accept `_inspect=true` as a query param that will result in the underlying ES query being outputted in the Kibana backend process.
+
+Example:
+`/api/apm/services/my_service?_inspect=true`
