+# Shared bootdir helper
+
+## Problem to solve
+
+You may have multiple linux installations, and they want to share the same `/boot` directory. 
+However, each of them want different kernel paramters. 
+
+This scenario usually appears while you want to deniable-encrypt all your computers, without 
+bringing tons of USB sticks with you. 
+
+## What this package do
+
+1. Add a pre-transaction hook to make sure you have inserted your USB stick before upgrading kernel. 
+2. Add a post-transaction hook to rename your kernel file basing on hostname, to avoid conflicting with other installations. 
+3. Modify `mkinitcpio.conf` to tell mkinitcpio about the new filename of your kernel file. 
+4. Modify `/etc/default/grub` to allow external script to manage kernel parameters. 
+5. Add a post-transaction hook after `grub-mkconfig`, to automatically set kernel parameters for every boot entry. 
+
+> I don't think it's a good idea for a package to modify others configuration file. I'm reviewing the design to see if there's any better solution.
