+## Self-hosting
-You can serve the application with a webserver of your choice by simply copying `dist/` directory to the webroot. 
+To host Cinny on your own, simply download the tarball from [GitHub releases](https://github.com/cinnyapp/cinny/releases/latest), and serve the files from `dist/` using your preferred webserver. Alternatively, you can just pull the docker image from [DockerHub](https://hub.docker.com/r/ajbura/cinny) or [GitHub Container Registry](https://github.com/cinnyapp/cinny/pkgs/container/cinny).
-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'`.

-between multiple Node.js versions based on the needs of different projects you're working on. [NVM on windows](https://github.com/coreybutler/nvm-windows#installation--upgrades) on Windows and [nvm](https://github.com/nvm-sh/nvm) on Linux/macOS are pretty good choices.
