 /**
  * The {@code PermitContext} class represents the context for Permit API calls.
- * 
- * A context can be: the entire workspace, a specific project, or a specific environment.
- * Most API methods require an environment scope (e.g: in order to create a role you
- * need to know in which environment to place it), but some methods can work in higher
- * scopes (for example: creating a project can be done with a workspace-level scope).
+ *
+ * Since the Permit API hierarchy is deeply nested, it is less convenient to specify
+ * the full object hierarchy in every request.
+ *
+ * For example, in order to list roles, the user needs to specify the (id or key) of the:
+ * - the org
+ * - the project
+ * - then environment
+ * in which the roles are located under.
+ *
+ * Instead, the SDK can "remember" the current context and "auto-complete" the details
+ * from that context.
+ *
+ * We then get this kind of experience:
+ * <pre>{@code
+ * permit.api.roles.list();
+ * }</pre>
+ *
+ * We can only run this function if the current context already knows the org, project,
+ * and environment that we want to run under, and that is why in this example the api
+ * method assumes we are running under an {@link ApiContextLevel#ENVIRONMENT} context.
