 About ``codeql-pack.lock.yml`` files
 ------------------------------------
 
-``codeql-pack.lock.yml`` files store the versions of the resolved transitive dependencies of a CodeQL pack. This file is created by the ``codeql pack install`` if it does not already exist and should be added to your version control system. The ``dependencies`` section of the ``qlpack.yml`` file contains version ranges that are compatible with the pack. The ``codeql-pack.lock.yml`` file locks the versions to precise dependencies. This ensures that anyone running ``codeql pack install`` on this the pack will always retrieve the same versions of dependencies even if newer compatible versions exist. Only query packs can have ``codeql-pack.lock.yml`` files. This is because library packs are not compiled independently of query packs. Without being compiled, there is no need to specify precise versions of their dependencies.
