+# :bookmark_tabs:Scoop guidelines
+
+[Scoop](https://scoop.sh/) is a command-line installer for Windows.
+
+# :rocket:Get started
+
+For now, to manually and locally install `vendir` :
+
+```
+git clone https://github.com/vmware-tanzu/carvel-vendir.git
+cd carvel-vendir
+export TARGET_VERSION=0.21.1
+sed 's/$VENDIR_VERSION/'"$TARGET_VERSION"'/g' vendir.json.template > vendir.json
+scoop install vendir
+```
+
+# :point_right:To do
+
+To get this from a central repo, it is highly recommended to create a 
+dedicated [Scoop Bucket](https://github.com/lukesampson/scoop/wiki/Buckets).
