 ## Deployment
 
-Only static Nuxt deployments (SSG) are supported at this time. This is due to a limitation in the way the Pinia and local storage Nuxt modules (i.e. the `defineStore()` and `useLocalStorage()` composables) work when Nuxt's server-side rendering (SSR) is enabled.
-
-The basic problem is that hydration of the Pinia store on the client does not capture the locally-stored app state. Because of this, SSR is disabled with `ssr: false`. You may find additional details [here](https://github.com/krazkidd/lineup/pull/3).
+Only static Nuxt deployments (SSG) are supported at this time (`ssr: false`). This allows us to deploy to some free static hosting services. See [Hosting](#hosting).
