+# Dirpersist plugin
+
+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.
+
+To use it, add `dirpersist` to the plugins array in your zshrc file:
+
+```zsh
+plugins=(... dirpersist)
+```
