+
+Overview
+
+You can use the scratch plugin to create a temporary scratch buffer to store
+and edit text that will be discarded when you quit/exit vim. The contents
+of the scratch buffer are not saved/stored in a file.
+
+Installation
+
+1. Copy the scratch.vim plugin to the $HOME/.vim/plugin directory. Refer to
+   the following Vim help topics for more information about Vim plugins:
+
+      :help add-plugin
+      :help add-global-plugin
+      :help runtimepath
+
+2. Restart Vim.
+
+Usage
+
+You can use the following command to open/edit the scratch buffer:
+
+      :Scratch
+
+To open the scratch buffer in a new split window, use the following command:
+
+      :Sscratch
+
+When you close the scratch buffer window, the buffer will retain the
+contents. You can again edit the scratch buffer by openeing it using one of
+the above commands. There is no need to save the scatch buffer.
+
+When you quit/exit Vim, the contents of the scratch buffer will be lost.
+You will not be prompted to save the contents of the modified scratch
+buffer.
+
+You can have only one scratch buffer open in a single Vim instance. If the
+current buffer has unsaved modifications, then the scratch buffer will be
+opened in a new window
