+*****************************
+How does ``sunpy-soar`` work?
+*****************************
+
+``sunpy-soar`` is a Python library developed to interact with the SOAR (Solar Orbiter Archive) data
+hosted by ESA (European Space Agency). It provides tools and utilities to access, search, download and
+analyze data collected by the Solar Orbiter mission.
+
+How data is retrieved from SOAR
+==============================
+
+To retrieve data from SOAR, you first use the ``Fido`` object from SunPy
+and specify the desired attributes using `sunpy.net.attrs`. These
+attributes define the criteria for the data you want to retrieve, such as the
+time range, instrument, or wavelength. Here is an example of how to specify
+the time range for the data you want to retrieve:
+
+.. code-block:: python
+
+    import sunpy.net.attrs as a
+    from sunpy.net import Fido
+    import sunpy_soar
+
+    instrument = a.Instrument("EUI")
+    time = a.Time("2021-02-01", "2021-02-02")
+    level = a.Level(1)
+    product = a.soar.Product("EUI-FSI174-IMAGE")
+
+    result = Fido.search(instrument & time & level & product)
+
+
+``sunpy-soar`` constructs the query based on the specified criteria, then generates a URL to interact with the SOAR API.
+This is done by using the Table Access Protocol (TAP), a widely adopted standard in the astronomical community for accessing large datasets.
+The results are returned in the form of an Astropy table, providing a structured and efficient format for further analysis and visualization within the Python environment.
