 The detail of DVC version depends upon the way of installing DVC.
 
-- **Official release**: [These instructions](/doc/install) include ways to
-  install DVC using the official package stored in Python Packaging Authority.
-  We mark these official releases with tags on DVC's repository. Any issues
-  reported with the official build can be traced using the `_BASE_VERSION`

-- **Development version**: `pip install git+git://github.com/iterative/dvc` will

+- **Development version**: will

   The master branch is constantly updated with changes that might not be ready
-  to publish yet. Therefore, installing with this method might result in usage
-  issues. To trace any error reported with this setup, we need to know exactly
-  which version is being used. For this we rely on a Git commit hash that is
-  displayed in the output of `dvc version` like this: `0.40.2+292cab.mod`. The
-  part before `+` is the `_BASE_VERSION`, and the following part is the commit
-  hash of the tip of the `master` branch. The optional suffix `.mod` means that
-  code is modified.
