 #### Calling `nvm use` automatically in a directory with a `.nvmrc` file
 
-##### zsh
+This shell function will install (if needed) and `nvm use` the specified Node version when an `.nvmrc` is found, and `nvm use default` otherwise.
 
-Put this into your `$HOME/.zshrc` to call `nvm use` automatically whenever you enter a directory that contains an
+```sh
-`.nvmrc` file with a string telling nvm which node to `use`:
-
-```zsh
-# place this after nvm initialization!
-autoload -U add-zsh-hook
 load-nvmrc() {
   local node_version="$(nvm version)"

+In your profile (`~/.bash_profile`, `~/.zshrc`, `~/.profile`, or `~/.bashrc`), add `load-nvmrc` along with one of the following hook listeners to call `load-nvmrc` whenever you enter a new directory:

-Put this into `$HOME/.bashrc` (or `$HOME/.bash_profile`, or whatever you use) to override the `cd` command to mimic the above zsh-hook:

-```bash
-# place this after nvm initialization!
-load-nvmrc() {
-  # same definition as zsh-hook

-load-nvmrc
 
+```sh
+# note: overrides the `cd` command
 cd() {
    builtin cd "$1"
    load-nvmrc
 }
