+# Add To Path Via Path Array
+
+Typically when managing what is on your path in a Unix shell environment, you
+override the `PATH` environment variable with `export`. This is usually an
+append or prepend to bring along the existing path entries.
+
+```bash
+$ export PATH="$PATH:/Users/me/.local/bin"
+```
+
+The `zsh` shell environment exposes another way of adding to your path. They
+have a `path` array which can be a little easier to work with since you can use
+an array operation instead of string interpolation.
+
+Here is how we'd do the same as above:
+
+```bash
+$ path+=/Users/me/.local/bin
+```
+
+This works because there is an automatic linking in zsh between arrays and
+colon-separated strings (_scalars_).
