+### Dev URLs
+
+Coder allows you to access services you're developing in your workspace via [dev
+URLs](../../workspaces/devurls.md). You can enable dev URLs after you've
+installed Coder.
+
+> If you do not want to enable dev URLs, you can use SSH port forwarding or
+> tools like [ngrok][ngrok-url] to preview webpages from inside you workspace.
+
+1. To use dev URLs, you must have a wildcard subdomain. One option to meet this
+   requirement is to use a service such as [nip.io][nip-url] to route domains to
+   a local IP address.
+
+1. [Update Coder](../updating.md#update-coder) with the following Helm values
+   added for either your local (`127.0.0.1`) or private (e.g., `192.168.1.x`)
+   address:
+
+   ```yaml
+   ingress:
+   host: "127.0.0.1.nip.io"
+   devurls:
+   host: "*.127.0.0.1.nip.io"
+   ```
+
+Alternatively, you can use [dnsmasq][dnsmasq-url] to create local domains (e.g.,
+`http://dashboard.coder` and `http://*.coder`). This may be useful if you do not
+want to rely on an external service/network or if your network has DNS rebinding
+protection. Here's how to do this:
+
+1. Install dnsmasq
+
+   ```console
+   # Mac OS
+   brew install dnsmasq
+
+   # Linux (Ubuntu)
+   sudo apt-get install dnsmasq
+   ```
+
+1. Create a dnsmasq configuration for the `.coder` domain
+
+   ```console
+   # Mac OS
+   sudo touch $(brew --prefix)/etc/dnsmasq.d/coder.conf
+   sudo vim $(brew --prefix)/etc/dnsmasq.d/coder.conf
+
+   # Linux (Ubuntu)
+   sudo touch /etc/dnsmasq.d/coder.conf
+   sudo vim /etc/dnsmasq.d/coder.conf
+   ```
+
+   ```conf
+   # coder.conf
+   address=/coder/127.0.0.1
+   ```
+
+1. Add dnsmasq as DNS resolver on your machine
+
+   ```console
+   # Mac OS: this will only route
+   # .coder domains to dnsmasq
+   sudo mkdir -p /etc/resolver
+   sudo touch /etc/resolver/
+   sudo vim /etc/resolver/coder
+
+   # Linux (Ubuntu)
+   # add to top of the file
+   sudo vim /etc/resolv.conf
+   ```
+
+   ```text
+   nameserver 127.0.0.1
+   ```
+
+1. [Update Coder](../updating#update-coder) with these Helm values added to use
+   your new domains:

+   host: "dashboard.coder"
