+### Euro-Office Integration
+
+First, deploy the [Euro-Office Recipe](https://recipes.coopcloud.tech/euro-office),
+and keep its JWT secret. Then configure your nextcloud instance with:
+
+`abra app config <app-name>`
+
+Configure the following envs with the URL of the euro-office service:
+```
+COMPOSE_FILE="$COMPOSE_FILE:compose.eurooffice.yml"
+EUROOFFICE_URL=https://euro-office.example.com
+SECRET_EURO_JWT_VERSION=v1
+```
+
+Then set the euro-office JWT secret from the euro-office installation:
+
+`abra app secret insert <app-name> euro_jwt v1 <jwt_secret>`
+
+Now make sure that your nextcloud recipe is correctly deployed.
+If it's a fresh install, deploy it, if Euro-Office is added after
+the install, force-deploy it to update the configuration variables:
+
+`abra app deploy -f <app-name>`
+
+Once that is up and running, install the eurooffice plugin for nextcloud:
+
+`abra app cmd <app-name> app install_eurooffice`
+
 ### BBB Integration

+Upgrades Nextcloud from 33 to 34 (major version upgrade).
+
+IMPORTANT:
+- Do not skip major versions: your instance must be on the latest 33.x before
+  upgrading to 34.
+- Use `check_major_upgrade` (`abra app cmd <app-name> app check_major_upgrade`)
+  to check whether an instance is ready to upgrade to the next Nextcloud
+  major version.
+- Nextcloud does NOT support downgrades. Take a backup before deploying.
+- After deploying, check the logs and run any pending repair/upgrade steps:
+  `abra app cmd <app> app run_occ '"app:update --all"'`
+- Review app (plug-in) compatibility with Nextcloud 34 before upgrading; some
+  apps may need to be updated or temporarily disabled.
+
+- This release adds support for Euro-Office, see the README.md for instructions.
