 ``mapflow`` transforms 3D ``xr.DataArray`` into video files in one line of code.
 
+Installation
+------------
+
+You can install ``mapflow`` using ``pip`` or ``conda``.
+
+With pip
+~~~~~~~~
+
+.. code-block:: bash

+With conda
+~~~~~~~~~~
+
+.. code-block:: bash

+
+The main function of ``mapflow`` is ``animate``, which creates a video from an ``xarray.DataArray``.
+
+.. code-block:: python
+
+   import xarray as xr
+   from mapflow import animate
+
+   ds = xr.tutorial.open_dataset("era5-2mt-2019-03-uk.grib")
+   animate(da=ds['t2m'].isel(time=slice(120)), path='animation.mp4')
+
+.. video:: ../_static/animation.mp4
