-## Bio-Logic .mpr files ##
+# Usage
+
+## Bio-Logic .mpr files
 
 Use the `MPRfile` class from BioLogic.py (exported in the main package)
 
-````
+```python
 from galvani import BioLogic
 import pandas as pd
 
 mpr_file = BioLogic.MPRfile('test.mpr')
 df = pd.DataFrame(mpr_file.data)
-````
+```
+
+## Arbin .res files
+
+Use the `./galvani/res2sqlite.py` script to convert the .res file to a sqlite3 database with the same schema, which can then be interrogated with external tools or directly in Python.
+For example, to extract the data into a pandas DataFrame (will need to be installed separately):
+
+```python
+import sqlite3
+import pandas as pd
+from galvani.res2sqlite import convert_arbin_to_sqlite
+convert_arbin_to_sqlite("input.res", "output.sqlite")
+with sqlite3.connect("output.sqlite") as db:
+    df = pd.read_sql(sql="select * from Channel_Normal_Table", con=db)
+```
+
+This functionality requires [MDBTools](https://github.com/mdbtools/mdbtools) to be installed on the local system.
+
+# Installation
