+
+- Command line options `--profile` to use a named profile, `--credentials-file` flag to use the specified credentials file
+
+    ```sh
+    # Use your company profile in AWS default credential file
+    s5cmd --profile my-work-profile ls s3://my-company-bucket/
+
+    # Use your company profile in your own credential file
+    s5cmd --credentials-file ~/.your-credentials-file --profile my-work-profile ls s3://my-company-bucket/

+While executing the commands, `s5cmd` detects the region according to the following order of priority:
+
+1. `--source-region` or `--destination-region` flags of `cp` command.
+2. `AWS_REGION` environment variable.
+3. Region section of AWS profile.
+4. Auto detection from bucket region (via `HeadBucket` API call).
+5. `us-east-1` as default region.
