 This flag allows you to pass in ARG values at build time, similarly to Docker.
 You can set it multiple times for multiple arguments.
 
+Note that passing values that contain spaces is not natively suppored - you need to ensure that the IFS is set to null before your executor command.
+You can set this by adding `export IFS=''` before your executor call. 
+See the following example
+
+```bash
+export IFS=''
+/kaniko/executor --build-arg "MY_VAR='value with spaces'" ...
+```

 #### --cache
 
 Set this flag as `--cache=true` to opt into caching with kaniko.
