+### Docker
 
-1.  [Download a binary](https://github.com/codercom/code-server/releases) (Linux and OSX supported. Windows coming soon)
+See docker oneliner mentioned above. Dockerfile is at [/Dockerfile](/Dockerfile).
+
+### Binaries
+
+1.  [Download a binary](https://github.com/codercom/code-server/releases) (Linux and OS X supported. Windows coming soon)
 2.  Start the binary with the project directory as the first argument
 
     ```
-    code-server <inital directory to open>
+    code-server <initial directory to open>
     ```
 	> You will be prompted to enter the password shown in the CLI
-	`code-server` should now be running at https://<IP>:8443.
+	`code-server` should now be running at https://localhost:8443.

 ### Known Issues

+- Creating custom VS Code extensions and debugging them doesn't work.
 
 ### Future
-
+- **Stay up to date!** Get notified about new releases of code-server.
+  ![Screenshot](/doc/assets/release.gif)
 - Windows support.
-- Electron and ChromeOS applications to bridge the gap between local<->remote.
+- Electron and Chrome OS applications to bridge the gap between local<->remote.
 - Run VS Code unit tests against our builds to ensure features work as expected.
 
+### Extensions
+
+At the moment we can't use the official VSCode Marketplace. We've created a custom extension marketplace focused around open-sourced extensions. However, if you have access to the `.vsix` file, you can manually install the extension.
+
+## Telemetry
+
+Use the `--disable-telemetry` flag or set `DISABLE_TELEMETRY=true` to disable tracking ENTIRELY.
+
+We use data collected to improve code-server.

+# Installng code-server in your ChromiumOS/ChromeOS/CloudReady machine
+
+This guide will show you how to install code-server into your CrOS machine.
+
+## Using Crostini
+
+One of the easier ways to run code-server is via [Crostini](https://www.aboutchromebooks.com/tag/project-crostini/), the Linux apps support feature in CrOS. Make sure you have enough RAM, HDD space and your CPU has VT-x/ AMD-V support. If your chromebook has this, then you are qualified to use Crostini.
+
+If you are running R69, you might want to enable this on [Chrome Flags](chrome://flags/#enable-experimental-crostini-ui). If you run R72, however, this is already enabled for you.
+
+After checking your prerequisites, follow the steps in [the self-host install guide](index.md) on installing code-server. Once done, make sure code-server works by running it. After running it, simply go to `penguin.linux.test:8443` to access code-server. Now you should be greeted with this screen. If you did, congratulations, you have installed code-server in your Chromebook!
+
+![code-server on Chromebook](../assets/cros.png)
+
+Alternatively, if you ran code-server in another container and you need the IP for that specific container, simply go to Termina's shell via `crosh` and type `vsh termina`.
+
+```bash
+Loading extra module: /usr/share/crosh/dev.d/50-crosh.sh
+Welcome to crosh, the Chrome OS developer shell.
+
+If you got here by mistake, don't panic!  Just close this tab and carry on.
+
+Type 'help' for a list of commands.
+
+If you want to customize the look/behavior, you can use the options page.
+Load it by using the Ctrl+Shift+P keyboard shortcut.
+
+crosh> vsh termina
+(termina) chronos@localhost ~ $
+```
+While in termina, run `lxc list`. It should output the list of running containers.
+
+```bash
+(termina) chronos@localhost ~ $ lxc list
++---------+---------+-----------------------+------+------------+-----------+
+|  NAME   |  STATE  |         IPV4          | IPV6 |    TYPE    | SNAPSHOTS |
++---------+---------+-----------------------+------+------------+-----------+
+| penguin | RUNNING | 100.115.92.199 (eth0) |      | PERSISTENT | 0         |
++---------+---------+-----------------------+------+------------+-----------+
+(termina) chronos@localhost ~ $ 
+```
+
+For this example, we show the default `penguin` container, which is exposed on `eth0` at 100.115.92.199. Simply enter the IP of the container where the code-server runs to Chrome.
+
+## Using Crouton
+
+[Crouton](https://github.com/dnschneid/crouton) is one of the old ways to get a running full Linux via `chroot` on a Chromebook. To use crouton, enable developer mode and go to `crosh`. This time, run `shell`, which should drop you to `bash`.
+
+Make sure you downloaded `crouton`, if so, go ahead and run it under `~/Downloads`. After installing your chroot container via crouton, go ahead and enter `enter-chroot` to enter your container.
+
+Follow the instructions set in [the self-host install guide](index.md) to install code-server. After that is done, run `code-server` and verify it works by going to `localhost:8443`.
+
+> At this point in writing, `localhost` seems to work in this method. However, the author is not sure if it applies still to newer Chromebooks.

+  Example of https virtualhost configuration for Apache as a reverse proxy. Please also pass --allow-http on code-server startup to allow the proxy to connect.
+  ```
+  <VirtualHost *:80>
+    ServerName code.example.com
+
+    RewriteEngine On
+    RewriteCond %{HTTP:Upgrade} =websocket [NC]
+    RewriteRule /(.*)           ws://localhost:8443/$1 [P,L]
+    RewriteCond %{HTTP:Upgrade} !=websocket [NC]
+    RewriteRule /(.*)           http://localhost:8443/$1 [P,L]
+    
+    ProxyRequests off
+
+    RequestHeader set X-Forwarded-Proto https
+    RequestHeader set X-Forwarded-Port 443
+
+    ProxyPass / http://localhost:8443/ nocanon
+    ProxyPassReverse / http://localhost:8443/
+
+  </VirtualHost>
+  ```
+  *Important:* For more details about Apache reverse proxy configuration checkout the [documentation](https://httpd.apache.org/docs/current/mod/mod_proxy.html) - especially the [Securing your Server](https://httpd.apache.org/docs/current/mod/mod_proxy.html#access) section
