-# 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_).

-# Link A Scalar To An Array
-
-`Zsh` has a builtin command `typeset` that does a variety of things. When given
-the `-T` flag and the names of a scalar and an array, it will link them
-together so that a change to one is reflected in the other.
-
-The scalar is a string of values delimited by a colon (`:`). The array is an
-array that can be interacted with using array operations like append (`+=`).
-
-```bash
-$ typeset -T FOO foo
-
-$ echo $FOO
-
-
-$ export FOO="one:two"
-
-$ echo $foo
-one two
-
-$ foo+=three
-
-$ echo $FOO
-one:two:three
-```
-
-Notice `FOO` is initially empty. I then `export` it to overwrite it with two
-values delimited by a colon. Since `foo` is automatically kept in sync, I can
-`echo $foo` and see those values displayed as an array. I can then append a
-third value using an array operation on `foo`. The update will be automatically
-reflected in `FOO`.
-
-`Zsh` does this under the hood for `PATH` and `path` which is why you can [add
-to the path via the path array](add-to-the-path-via-path-array.md).
-
-See `man zshbuiltins` for more details.
