+YAML Configuration
+==================
+
+Command-line arguments can be passed by a configuration yaml file via :code:`--config_path`.
+
+.. seealso::
+
+   :doc:`Command-line interface <./cli>`
+        Overview of the command-line interface.
+
+This is an example of COMET-MBR.
+:code:`hypotheses.txt` are also used as the pseudo-references.
+
+.. code-block:: bash
+
+    mbrs-decode \
+      hypotheses.txt \
+      --num_candidates 1024 \
+      --nbest 1 \
+      --source sources.txt \
+      --references hypotheses.txt \
+      --output translations.txt \
+      --report report.txt --report_format tsv \
+      --decoder mbr \
+      --metric comet \
+      --metric.model Unbabel/wmt22-comet-da \
+      --metric.batch_size 64 --metric.fp16 true
+
+All arguments can be passed via :code:`--config_path`,
+
+.. code-block:: bash
+
+   mbrs-decode --config_path comet_mbr.yaml
+
+with a configuration yaml:
+
+.. code-block:: yaml
+   :caption: comet_mbr.yaml
+
+   common:
+     hypotheses: hypotheses.txt
+     num_candidates: 1024
+     nbest: 1
+     source: sources.txt
+     references: hypotheses.txt
+     output: translations.txt
+     report: report.txt
+     report_format: tsv
+     decoder: mbr
+     metric: comet
+
+   metric:
+     model: Unbabel/wmt22-comet-da
+     batch_size: 64
+     fp16: true
+
+The arguments with dot-prefixes are loaded from each key in the yaml, and others are loaded from the :code:`common:` key.
+In other words, :code:`--metric.` and :code:`--decoder.` are loaded from each corresponding key in the yaml, i.e., :code:`metric:` or :code:`decoder:`.
+
+Of course, you can override the values via command-line arguments, for example:
+
+.. code-block:: bash
+
+   mbrs-decode --config_path comet_mbr.yaml --nbest 1024
