+At Elastic, all products in the stack, including Kibana, are released at the same time with the same version number. Most of these projects have the following branching strategy:
+
+* `master` is the next major version.
+* `<major>.x` is the next minor version.
+* `<major>.<minor>` is the next release of a minor version, including patch releases.
+
+As an example, let's assume that the `7.x` branch is currently a not-yet-released `7.6.0`. Once `7.6.0` has reached feature freeze, it will be branched to `7.6` and `7.x` will be updated to reflect `7.7.0`. The release of `7.6.0` and subsequent patch releases will be cut from the `7.6` branch. At any time, you can verify the current version of a branch by inspecting the `version` attribute in the `package.json` file within the Kibana source.
+
+Pull requests are made into the `master` branch and then backported when it is safe and appropriate.
+
+* Breaking changes do not get backported and only go into `master`.
+* All non-breaking changes can be backported to the `<major>.x` branch.
+* Features should not be backported to a `<major>.<minor>` branch.
+* Bugs can be backported to a `<major>.<minor>` branch if the changes are safe and appropriate. Safety is a judgment call you make based on factors like the bug's severity, test coverage, confidence in the changes, etc. Your reasoning should be included in the pull request description.
+* Documentation changes can be backported to any branch at any time.

 ```
 
+## Remarks
+
+By default, a plugin inherits it's current status from the most severe status level of any Core services and any plugins that it depends on. This default status is available on the  API.
+
+Plugins may customize their status calculation by calling the  API with an Observable. Within this Observable, a plugin may choose to only depend on the status of some of its dependencies, to ignore severe status levels of particular Core services they are not concerned with, or to make its status dependent on other external services.
+
+## Example 1
+
+Customize a plugin's status to only depend on the status of SavedObjects:
+
+```ts
+core.status.set(
+  core.status.core$.pipe(
+.   map((coreStatus) => {
+      return coreStatus.savedObjects;
+    }) ;
+  );
+);
+
+```
+
+## Example 2
+
+Customize a plugin's status to include an external service:
+
+```ts
+const externalStatus$ = interval(1000).pipe(
+  switchMap(async () => {
+    const resp = await fetch(`https://myexternaldep.com/_healthz`);
+    const body = await resp.json();
