+
+### Add support for the config file
+
+You can now use the config file to change the default values of stern options. The default config file path is `~/.config/stern/config.yaml`.
+
+```yaml
+# <flag name>: <value>
+tail: 10
+max-log-requests: 999
+timestamps: short
+```
+
+You can change the config file path with `--config` flag or `STERNCONFIG` environment variable.
