Installing CKEditor

Hello,

I'm trying to install CKEditor. I've unzipped the files and placed them at addons/plugins/editors/ckeditor. My template is below:

                <div class="col-sm-6">
                    <div class="card">
                        <div class="card-body">
                            <h5 class="card-title"><perch:content id="office_name" type="text" label="Office name" title="true" required></h5>
                            <p class="card-text office"><perch:content id="office_details" type="textarea" label="Office details" editor="ckeditor" html=“true”></p>
                        </div>
                    </div>
                </div>

When I go into the Perch panel, CKEditor isn't showing up. Do I need to add CKEditor to my apps file or something? I was referencing the documentation (https://docs.grabaperch.com/addons/plugins/installing/) and have followed the steps listed.

Thank you in advance for your assistance, Trevor Brandt
