# Read with CDisplayEx
The premium version of CDisplayEx (opens new window) for Android allows you to connect to Komga using the REST API.
If you have disabled the page dimensions analysis option, re-enable it, it is necessary to open books with CDisplayEx.
# Add a new location
On the home page, use the big + button at the bottom right to add a new location. Then choose the Komga option from the list that appears. A dialog box appears asking you to enter some information.
You can specify an IP Address or a host name to identify the remote server.
Here are some examples:
192.168.1.12, computer.local, demo.komga.org, user.host.net/komga
Enter your username and password.
Specify a port number if you are using a different port than the one used by default by the HTTP or HTTPS protocols. If you are using HTTPS, check the SSL option.
If you are using a self-signed certificate and don't want to add it to your device, there is an experimental option to disable SSL certificate verification.
The application uses a virtual folder structure to browse books by library, series, collections and reading lists. Select a folder to make only part of your library accessible. If you want to make everything accessible, leave the path blank.
Add a description and leave the other options checked.
Now press the ADD button, the synchronization will start, depending on the size of your library and the performance of your server, it may take a few minutes or a few seconds. You will be notified when this operation is complete.
# Nested folders
Without waiting for the synchronization to complete, you can browse folders by tapping on the location that was just added to the home page. In this view, the server must be reachable. You will be able to navigate in a virtual folder structure.
