+Sumo Utilities
+#############
+
+The ``fmu.sumo.utilities`` is a python package for integrating other tools into the FMU-SUMO ecosystem.
+So far the only utility available is the utility sim2sumo which facilitates upload of results from
+reservoir simulators such as eclipse and opm flow as csv or arrow format files.
+
+sim2sumo
+--------
+.. note::
+
+  **sim2sumo** couples together three packages often used in the FMU sphere.
+  * **fmu-dataio** the FMU plugin for exporting data out of FMU workflows with rich metadata.
+  * **ecl2df**, a plugin not strictly tied down to FMU, but often used in this domain
+  * **fmu.sumo.uploader**, a plugin that uploads files exported to disc with metadata to sumo
+

+Usage and examples
+------------------
+
+Config settings
+------------------------------
+
+sim2sumo is set up such that you provide a config file with the section sim2sumo defined.
+The config file needs to be in yaml format. You can add this to the global_variables for the case,
+or make your own file. The file needs to contain two parts:
+1. The metadata needed for the upload to sumo, that is the three sections model, masterdata, and access
+2. A section named sim2sumo. There are several ways to define this section sim2sumo.
+
+Simplest case
+^^^^^^^^^^^^^^
+This is a snippet of the ``global_variables.yml`` containing enough data to upload to sumo with sum2sumo.
+ In real cases this file will be much longer. When the entire section for sum2sumo is equal to ''sim2sumo: true''
+ sim2sumo will extract from all simulation runs in a folder called eclipse/model/ relative to where you are running from,
+ and at the same time export all datatypes available. See the example file below.
+
+.. toggle::
+
+   .. literalinclude:: ../tests/data/reek/realization-0/iter-0/fmuconfig/output/global_variables.yml
+      :language: yaml
+
+|
+Case where eclipse datafile is explicitly defined
+^^^^^^^^^^^^^^
+This is a snippet of the ``global_variables.yml`` file which holds the static metadata described in the
+`previous section <./preparations.html>`__. In real cases this file will be much longer.
+
+.. toggle::
+
+   .. literalinclude:: ../tests/data/reek/realization-0/iter-0/fmuconfig/output/global_variables_w_eclpath.yml
+      :language: yaml
+
+|
+Case where eclipse datafile, what types to export, and options to use are explicitly defind
+^^^^^^^^^^^^^^
+This is a snippet of the ``global_variables.yml`` file which holds the static metadata described in the
+`previous section <./preparations.html>`__. In real cases this file will be much longer.
+
+.. toggle::
+
+   .. literalinclude:: ../tests/data/reek/realization-0/iter-0/fmuconfig/output/global_variables_w_eclpath_and_extras.yml
+      :language: yaml
+
+|
+
+Exporting data from eclipse with metadata
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+This code exports summary data results from simulation
+.. code-block::
+
+    from fmu.sumo.utilities.sim2sumo as s2s
+
+    DATAFILE = "eclipse/model/2_REEK-0.DATA"
+    CONFIG_PATH = "fmuconfig/output/global_variables.yml"
+    SUBMODULE = "summary"
+    s2s.export_csv(DATAFILE, SUBMODULE, CONFIG_PATH)
+
+As a FORWARD_MODEL in ERT
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. code-block::
+
+    FORWARD_MODEL SIM2SUMO
+
+
+Example above uploads all surfaces dumped to ``share/results/maps``. You don't need to have more
+than one instance of this job, it will generate and upload the data specified in the corresponding
+config file.
