 Make it executable with `chmod +x $HOME/.gnupg/pinentry-wrapper` and then edit your `$HOME/.gnupg/gpg-agent.conf` to include `pinentry-program $HOME/.gnupg/pinentry-wrapper`.
 
+## SmartCard Support
+Using a [Smart Card](https://en.wikipedia.org/wiki/Smart_card) such as a [YubiKey](https://www.yubico.com/) with pass simply requires setting up your GPG key to recognize your card.
+
+First, you will need to install `scdaemon` & enable the service on your system in order to recognize your smartcards. After you set this up, you can check if your card is recognized with the `gpg --card-status` command.
+
+Edit your GPG key with `gpg --edit-key [Your-Key-ID]` & run the follow commands in the interactive session:
+```
+key 1
+keytocard
+save
+```

+## Ideas & TODO
+- Hash file names for obsurity *(`pass rm <entry>` & `pass mv <entry>` since file names will be hashed)*
+- Better way than using a hard coded `GPG_ID` & maybe on the fly `METHOD` selection
