Most Internet Service Providers (ISP) offer a service called "Create Your Own Home Page", which is probably the best way to get started.
To have full control over your Home Page, take the time to learn HTML. You could also use an HTML editor which hides most of the complexity of HTML. Remember that not all HTML editors are up to date when it comes to support for new HTML tags or more advanced stuff, like Cascading Style Sheets and JavaScript.
If you have to create the subdirectories on your web site manually, you'll need a terminal emulator. You'll also need a File Transfer Program to copy the files from your local hard drive to the web server.
When you start EWAN, you must enter the name of your ISP (e.g. login.eunet.no). When you see the "%"-prompt, type your user name and press Enter. Then type your password and press Enter. The name of the directory you must create may vary from ISP to ISP. For example, Scandinavia Online uses www_docs, while Eunet uses www. Check with your ISP.Here are the UNIX commands you need;
cd www_docs
chmod -R a+rx *.*
