+Setup the EVerest Development Container
+#######################################
+
+There are two variants for the devcontainer setup:
+
+.. grid:: 1 2 2 2
+    :gutter: 2
+
+    .. grid-item-card:: Service Containers managed by VSCode
+        :link: /tutorials/setup-devcontainer/vscode
+        :link-type: doc
+
+        Uses the VSCode Dev Containers extension, which manages both
+        the devcontainer and the service containers.
+
+    .. grid-item-card:: Service Containers managed by devrd cli
+        :link: /tutorials/setup-devcontainer/devrd
+        :link-type: doc
+
+        Uses the devrd cli to manage the service containers.
+        This variant can be used if one is not using VSCode or needs dedicated
+        control over the service containers.
+
+Also consider these documents:
