+# Nextcloud Client Api
+
+This library is for interactive with Nextcloud instances.
+
+**Beware:** This library is NOT complete. I usually expand it by the functions I need. So, feel free to extend it with your APIs and your functions and submit a Pull Request with the changes.
+
+## How to use
+
+This is a simple shot how the library is intended to be used.
+
+*There are two ways to login. One is the LoginFlowV2.*
+
+```cs
+using NextcloudClient ncClient = new();
+var userInfo = ncClient.Login(creds);
+
+if (userInfo != null)
+{
+    var tableId = 16L;
+    var tablesClient = ncClient.GetClient<TablesClient>();
+    var rows = tablesClient.GetRows(tableId);
+    if (rows != null)
+    {
+        foreach (var row in rows)
+            Console.WriteLine(row.RowId);
+    }
+}
+```
