# Pinning the runtime

To run your application in a deterministic way, pin the version of the wolkenkit runtime. For that, open the application's package.json file and set the wolkenkit/runtime/version property to the version that you want to use.

E.g., to pin the runtime to version 3.1.0, use the following code:

"wolkenkit": {
  "runtime": {
    "version": "3.1.0"
  }  
}
