 ## Usage
+
+### Operation Modes
+
+Default Mode (Build and Push):
+
+When neither `no_push` nor `push_only` is provided. Plugin builds and pushes the Docker image to a container registry.
+
+Build-Only Mode (no-push):
+
+When `no_push` is true and `destination_tar_path` is defined.
+Plugin performs only the image build operation and saves the resulting image tarball to the specified `destination_tar_path`
+It does not push the image to any registry.
+
+Push-Only Mode (push-only):
+
+When `push_only` is true and `source_tar_path` is defined.
+Plugin loads an existing image tarball from the specified `source_tar_path`
+and pushes the loaded image to a Container Registry.

+This document explains on how to install certain git hooks globally for all repositories in your machine.
+
+Step 1: git clone https://github.com/drone/drone-kaniko.git
+Step 2: cd git-hooks
+Step 3: Run install.sh
+
+"install.sh" script will create .git_template in the user directory and will put the git hook and its dependent scripts in it. Along with the .git_template folder, it will add 2 sections "init" and "hooks boolean" in the .gitconfig file in the same user's root directory.
+After running "install.sh" if you create/clone a new git repository then all the hooks will get install automatically for the git repository. In case of existing git repository copy the contents of ~/.git_template/hooks into the .git/hooks directory of existing git repository.
