Upgrading Cook, Cleaver and Fridge

If you are upgrading from CUE Front version 1.5 to version 1.6.1-2, then your publication root folder will not contain a cue.yaml file as described below – you will need to create it.

To upgrade Cook, Cleaver and Fridge:

Open publication-folder/cue.yaml in an editor:
```
versions:
 cue-front: "old-version"
```
Replace the old version number with the number of the version you want to upgrade to:
```
versions:
 cue-front: "1.6.1-2"
```
Save the file.
Go to your CUE Front installation's setup folder and regenerate your configs:
```
cd cue-front-path/setup
docker-compose -f setup.yml run setup generate configuration-set
```
