-The TimeManager plugin offers a convenient way to navigate through the time
-dimension as shown in :numref:`fig_wms_qgis3`.
+Important parameter to consider while viewing the layers is the requested time interval,
+allowing for example to observe changes over years. One option is to manually add a custom **time=** parameter to the url after checking the `Ignore GetMap URI` checkbox. 
+
+For QGIS versions lower than 3.14, the only way how to use WMS layers with time support (WMS-T) was through a maintained plugin called `TimeManager <https://github.com/anitagraser/TimeManager>`_. It offers a convenient way to navigate through the time for raster and vector layers with custom defined steps as shown in :numref:`fig_wms_qgis3`.

+The plugin needs to be installed first and then set up with the desired layer. The raster layer to be added to TimeManager must be first added to the workspace as shown in :ref:`loading_qgis`. By clicking `Settings` button and following up with `Add raster` button as can be seen in :numref:`fig_wms_qgis4` it can be then chosen from list of layers. It is also suggested to add Start time and End time constrains to narrow down the interval which TimeManager will consider.

-  It even allows exporting an animation as shown in :numref:`fig_wms_qgis4` below.
+After setting the layer up, it is possible to change the time interval length (for example 1 month) and view all products in that interval. After clicking the `play` button, it displays the layer iteratively from defined Start time to End time, always displaying each frame for a set number of milliseconds.

+Second option available newly in QGIS Version 3.14 is to use added core support for WMS-T protocol called **Temporal Controller**. In detail video guide directly from the author of the feature can be seen on `video link <https://www.youtube.com/watch?v=vgDg5cRwPRw>`_
