+# Remove Gaps
+
+If you would like to remove all gaps by default, both between windows
+themselves, and between the monitor edges and the windows, you can set the
+following two configuration options to `0` in the `komorebi.json` configuration
+file.
+
+```json
+{
+  "default_workspace_padding": 0,
+  "default_container_padding": 0
+}
+```
