+### Azure B2C
+
+The following example shows how you can authenticate with Azure B2C using the [Client Credentials Flow](https://docs.microsoft.com/en-us/azure/active-directory-b2c/active-directory-b2c-reference-oauth-code#client-credentials-flow).
+
+This example is based on a JMeter example found at the [azure-ad-b2c/load-tests](https://github.com/azure-ad-b2c/load-tests) repository.
+
+To use this script, you need to:
+
+1. [Set up your own Azure B2C tenant](https://learn.microsoft.com/en-us/azure/active-directory-b2c/tutorial-create-tenant)
+    * Copy the tenant name, it will be used in your test script.
+1. [Register a web application](https://learn.microsoft.com/en-us/azure/active-directory-b2c/tutorial-register-applications?tabs=app-reg-ga)
+    * Register a single page application with the redirect URL of: https://jwt.ms. That's needed for the flow to receive a token.
+    * After the creation, you can get the Application (client) ID, and the Directory (tenant) ID. Copy both of them, they'll be used in your test script.
+1. [Create a user flow so that you can sign up and create a user](https://docs.microsoft.com/en-us/azure/active-directory-b2c/tutorial-create-user-flows)
+     * Create a new user, and copy the username and password. They'll be used in the test script.
+
+You can find the settings in the B2C settings in the Azure portal if you need to refer to them later on. Make sure to fill out all the variables for the `B2CGraphSettings` object, as well as replace `USERNAME` and `PASSWORD` in `export default function`.

+# Pod Termination
+
+A Pod Termination Fault allows terminating either a fixed number or a percentage of the pods that matching a selector or back a service.
+
+A Pod Termination fault is defined by the following attributes:
+
+| Attribute     | Type   | Description |
+| ------------- | ------ | --------|
+| count         | integer or percentage | the number of pods to be terminated. It can be specified as a integer number or as a percentage, for example `30%`, that defines the fraction of target pods to be terminated|
+
+{{% admonition type="note" %}}
+
+If the count is a percentage and there are no enough elements in the target pod list, the number is rounded up.
+For example '25%' of a list of 2 target pods will terminate one pod.
+If the list of target pods is not empty, at least one pod is always terminated.
+
+{{% /admonition %}}
+
+## Example
+
+This example defines a PorTermination fault that will terminate `30%` of target pods
+
+```javascript
+const fault = {
+    count: '30%'
+};
+```
