+## Use loaders: Load data from CSV files in just one line
+
+PyStreamAPI offers a convenient way to load data from CSV files. Like that you can start processing your CSV right away without having to worry about reading and parsing the file.
+
+You can import the loader with:
+
+```python
+from pystreamapi.loaders import csv
+```
+Now you can use the loader directly when creating your Stream:
+
+```python
+Stream.of(csv("data.csv", delimiter=";")) \
+    .map(lambda x: x["name"]) \
+    .for_each(print)
+```
