-### Lazy Loading (experimental)
+### Lazy Loading
 
 If you find `nvm` adds too much lag to your shell startup you can enable lazy loading by exporting the `NVM_LAZY_LOAD` environment variable and setting it to `true`. Lazy loading is around 70 times faster to load, however the first time you run `nvm`, `npm`, `node` or a global module you'll get a slight delay while `nvm` loads first. You'll only get this delay once per session.
