-# PRE-RELEASE project preview
-
-The idea of Pre-release is to let the project can be tried out before the official release when the project code is
-committed to npm with a new version assignment.
-
-GitHub action pre-release-branch-update takes action when an code update was pushed to the main (master)
-branch.  The action performs the project build, enabling save the result in git, and saves the result to
-the pre-release branch.
-
-Later, this code can be tested by adding to a test project using command
-*npm install https://github.com/ydb-platform/ydb-nodejs-sdk.git#pre-release*.
-
-When making changes to a project and building a new pre-release version by git push. It is **necessary**
-to update the code of the component in test projects via *npm update*.
