 By default Apache on Ubuntu serves from the `/var/www/html` directory. In this example, we'll use `/var/www/bookstack` to store our BookStack install. If you use a different path ensure you change that path in the below steps.
 Create this directory and follow the standard [BookStack install steps](/docs/admin/installation) to install BookStack into this folder. Once complete, following our example directory above, you should end up with a `.env` file in the `/var/www/bookstack` folder.

If the "DocumentRoot" of any configured host/site on the server points to, or includes, your BookStack installation folder (or a folder within it) then this will not work as expected and may introduce security issues.*

 On line 6 in the above, beginning with `Alias`, You'll need to change `"/bookstack"` path to be the web 'subdirectory' you want to serve BookStack on. For example, If you wanted to serve BookStack on `https://example.com/docs` this would be `"/docs"`. Any instances of `/var/www/bookstack` in the above will need to be changed to the folder you installed BookStack in. The `/public` part of these paths should remain.
