How to set Paging in AngularJS

<pagination style="margin-left: 850px;" total-items="totalItems" items-per-page="itemsPerPage"
ng-model="currentPage" ng-change="pageChanged()" class="pagination-sm" boundary-links="true"
previous-text="‹" next-text="›" first-text="«" last-text="»"></pagination>

<p ng-hide="true">
    total Items: {{totalItems}}
    <br />
    Items per page: {{itemsPerPage}}
    <br />
    Current Page: {{currentPage}}
</p>

$scope.itemsPerPage = 3
$scope.currentPage = 1;
$scope.maxSize = 5;
$scope.bigTotalItems = 175;
$scope.bigCurrentPage = 1;
$scope.pageCount = function() {
    return Math.ceil($scope.users.length / $scope.itemsPerPage);
};

$scope.$watch('currentPage + itemsPerPage', function() {
    var begin = (($scope.currentPage - 1) * $scope.itemsPerPage),
        end = begin + $scope.itemsPerPage;
    $scope.users = usersa.slice(begin, end);
});
});
