 ## SYNOPSIS
 
-`git lfs init`

+`git lfs init` --force
 
 ## DESCRIPTION
 
 Perform the following actions to ensure that Git LFS is setup properly:
 
-* Set up the clean and smudge filters under the name "lfs".
-* Install a pre-push hook to run git-lfs-push(1)
+* Set up the clean and smudge filters under the name "lfs" in the global Git

+* Install a pre-push hook to run git-lfs-pre-push(1) for the current repository,

+
+## OPTIONS
+
+Without any options, `git lfs init` will only setup the "lfs" smudge and clean
+filters if they are not already set.
+
+* `--force`:
+    Sets the "lfs" smudge and clean filters, overwriting existing values.
