 ### Q. Can I use it on Docker?
 Yes, but please note the followings.
 
-I recently found out that ALL errors that occur in environments with limited resources such as docker containers are due to **shared memory size**. So, if you want to use larger models with parallelformers in docker containers, **INCREASE the size of shared memory by --shm-size=?gb or REMOVE the limitation of shared memory size by --ipc=host**. the larger shared memory size is required if you want to use larger model.
