 You can serve the application with a webserver of your choice by simply copying `dist/` directory to the webroot.

+To set default Homeserver on login, register and Explore Community page, place a customized [`config.json`](config.json) in webroot of your choice.
+You will also need to setup redirects to serve the assests. An example setting of redirects for netlify is done in [`netlify.toml`](netlify.toml). You can also set `hashRouter.enabled = true` in [`config.json`](config.json) if you have trouble setting redirects.
+To deploy on subdirectory, you need to rebuild the app youself after updating the `base` path in [`build.config.ts`](build.config.ts). For example, if you want to deploy on `https://cinny.in/app`, then change `base: '/app'`.
