+#### Make release changes and push them to your personal fork
+
+```bash
+CHE_VERSION="7.7.0" && \
+BRANCH_NAME="7.7.x" && \
+FORK="l0rd/chectl" && \
+./make-release.sh ${CHE_VERSION} ${BRANCH_NAME} ${FORK}
+```

+#### Create a PR using `hub`
+

+
+```bash
+GH_USER="l0rd" && \
+RELEASE_ISSUE_LINK="https://github.com/eclipse/che/issues/15504" && \
+hub pull-request --browse \
+                 --base che-incubator:${BRANCH_NAME} \
+                 --head ${GH_USER}:${BRANCH_NAME} \
+                 -m "chore(release): release version ${CHE_VERSION}" \
+                 -m "### What does this PR do?" \

+                 -m "### What issues does this PR fix or reference?" \
