 ## Goals
 
-Every organization has policies. Some are essential to meet governance and legal requirements. Others help ensure adherance to best practices and institutional conventions. Attempting to ensure compliance manually would be error-prone and frustrating. Automating policy enforcement ensures consistency, lowers development latency through immediate feedback, and helps with agility by allowing developers to operate independently without sacrificing compliance.

 Kubernetes allows decoupling policy decisions from the inner workings of the API Server by means of [admission controller webhooks](https://kubernetes.io/docs/reference/access-authn-authz/extensible-admission-controllers/), which are executed whenever a resource is created, updated or deleted. Gatekeeper is a validating (mutating TBA) webhook that enforces CRD-based policies executed by [Open Policy Agent](https://github.com/open-policy-agent/opa), a policy engine for Cloud Native environments hosted by CNCF as an incubation-level project.

 The `location` element can specify either a simple subelement or an element in a list.
 For example the location `spec.containers[name:foo].imagePullPolicy` would be parsed as follows:
 - ***spec**.containers[name:foo].imagePullPolicy* - the spec element
-- *spec.**containers[name:foo]**.imagePullPolicy* - container subelement of spec. The container element is a list. Out of the list choosen, an element with the `name` element having the value `foo`.
+- *spec.**containers[name:foo]**.imagePullPolicy* - container subelement of spec. The container element is a list. Out of the list chosen, an element with the `name` element having the value `foo`.
