 ## How to build the package for a new Debian release
 
+Pre-tasks:
+
+* Execute shellcheck on scripts `*.sh` and fix or disable the relevant checks.
+* Prepare `linux/CHANGELOG` and `openbsd/CHANGELOG` for release.
+* Update version number is scripts :
+
+```
+sed -i 's/VERSION=".*"/VERSION="<MAJOR>.<MINOR>"/g' */evocheck*.sh
+```
+
 On the master branch, add the last stable version with a release tag.
 ```
