-## How is this different from VS Code Online?
+Feel free to file an issue to add a missing extension to the marketplace.
 
-VS Code Online is a closed source managed service by Microsoft and only runs on Azure.
+## Where are extensions stored?
 
-code-server is open source and can be freely run on any machine.

+If the `XDG_DATA_HOME` environment variable is set the data directory will be

+You can install an extension on the CLI with:

+## How is this different from VS Code Codespaces?
+
+VS Code Codespaces is a closed source and paid service by Microsoft. It also allows you to access
+VS Code via the browser.
+
+However, code-server is free, open source and can be ran on any machine without any limitations.
+
+While you can self host environments with VS Code Codespaces, you still need to an Azure billing
+account and you access VS Code via the Codespaces web dashboard instead of directly connecting to
+your instance.
 
 ## How should I expose code-server to the internet?
 
-By far the most secure method of using code-server is via
-[sshcode](https://github.com/codercom/sshcode) as it runs code-server and then forwards
-its port over SSH and requires no setup on your part other than having a working SSH server.
+Please follow [./guide.md]](./guide.md) for our recommendations on setting up and using code-server.
 
-You can also forward your SSH key and GPG agent to the remote machine to securely access GitHub

-If you cannot use sshcode, then you will need to ensure there is some sort of authorization in
-front of code-server and that you are using HTTPS to secure all connections.
-
-By default when listening externally, code-server enables password authentication using a
-randomly generated password so you can use that. You can set the `PASSWORD` environment variable
-to use your own instead. If you want to handle authentication yourself, use `--auth none`
-to disable password authentication.
+code-server only supports password authentication natively.
 
 **note**: code-server will rate limit password authentication attempts at 2 a minute and 12 an hour.
 
-If you want to use external authentication you should handle this with a reverse
-proxy using something like [oauth2_proxy](https://github.com/pusher/oauth2_proxy).
