+1. To generate bundle correctly please set env variables (default values for these variables you can check in makefile):
+```bash
+# operator version
+export VERSION=1.0.0
+# By default we use perconalab for tag owner. Please update this variable to use another repo
+export IMAGE_TAG_OWNER=percona
+# Min k8s version
+export MIN_KUBE_VERSION=1.27.0
+# Openshift versions:
+export OPENSHIFT_VERSIONS="v4.16-v4.20"
+# Set namespace or cluster (to generate bundles for cluster-wide)
+export MODE=namespace
+```
+2. Also it could be useful to check variable in makefile and update if you need something extra. For the most cases to update these variables is enough
+3. Update spec.description in bundle.csv.yaml with features added in this release.
+4. Run bundle generation:
+```bash
+# Generate all bundles community redhat and marketplace:
+make bundles
+# Generate only specific bundle:
+make bundles/community
+```
