 # Configuration
 
+## Setting Configuration Values
+
+There are three ways to pass in configuration:
+
+- Using the `~/.pyiceberg.yaml` configuration file
+- Through environment variables
+- By passing in credentials through the CLI or the Python API
+
+The configuration file is recommended since that's the easiest way to manage the credentials.
+
+To change the path searched for the `.pyiceberg.yaml`, you can overwrite the `PYICEBERG_HOME` environment variable.
+
+Another option is through environment variables:
+
+```sh
+export PYICEBERG_CATALOG__DEFAULT__URI=thrift://localhost:9083
+export PYICEBERG_CATALOG__DEFAULT__S3__ACCESS_KEY_ID=username
+export PYICEBERG_CATALOG__DEFAULT__S3__SECRET_ACCESS_KEY=password
+```
+
+The environment variable picked up by Iceberg starts with `PYICEBERG_` and then follows the yaml structure below, where a double underscore `__` represents a nested field, and the underscore `_` is converted into a dash `-`.
+
+For example, `PYICEBERG_CATALOG__DEFAULT__S3__ACCESS_KEY_ID`, sets `s3.access-key-id` on the `default` catalog.
