7+# Dirpersist plugin
8+
9+This plugin keeps a running tally of the previous 20 unique directories in the $HOME/.zdirs file. When you cd to a new directory, it is prepended to the beginning of the file.
10+
11+To use it, add `dirpersist` to the plugins array in your zshrc file:
12+
13+```zsh
14+plugins=(... dirpersist)
