+## Memory limit
+
+By default, the synchronizer command will use up to 128MB of memory.
+If it happens to need more memory, you can increase the memory limit by providing the `memory-limit` option when calling the command:

+You can specify the memory limit in the following formats: `128M`, `1G`, `1024M`, etc.
