 dbt generates the `package-lock.yml` file in the _project_root_ where `packages.yml` is recorded, which contains all the resolved packages, the first time you run `dbt deps`. Each subsequent run records the packages installed in this file. If the subsequent `dbt deps` runs contain no updated packages in `dependencies.yml` or `packages.yml`, dbt-core installs from `package-lock.yml`. 
 
-When you update the package spec and run `dbt deps` again, the package-lock and package files update accordingly. You can run `dbt deps --lock` to update the `package-lock.yml` with the most recent dependencies from `packages`.
+When you update the package spec and run `dbt deps` again, the `package-lock.yml` and `packages.yml` files update accordingly. 
+
+There are two flags related to `package-lock.yml`:
+- `dbt deps --upgrade` — creates or updates the `package-lock.yml` file with the most recent dependencies from `packages.yml` and installs them.
+- `dbt deps --lock` — creates or updates the `package-lock.yml` file but does not install the packages. 
 
 The `--add-package` flag allows you to add a package to the `packages.yml` with configurable `--version` and `--source` information. The `--dry-run` flag, when set to `False`(default), recompiles the `package-lock.yml` file after a new package is added to the `packages.yml` file. Set the flag to `True` for the changes to not persist.
