+# gpg-agent
+
+Applies some fixes for some common issues encountered with [GPG's gpg-agent](https://www.gnupg.org/documentation/manuals/gnupg/).
+
+More specifically, this plugin:
+
+- Updates the `GPG_TTY` environment variable before each shell execution. 
+- Updates the `SSH_AUTH_SOCK` environment variable if `enable-ssh-support` is turned on.
+
+To use it, add `gpg-agent` to the plugins array of your zshrc file:
+
+```zsh
+plugins=(... gpg-agent)
+```
