Drupal 8.x

When I finished drupal8 alpha4, I cannot click nothing. Everywhere I click,drupal told me"Not Found

The requested URL /admin/structure was not found on this server." Why?

I have just installed Drupal 8 Alpha 4 for development "hello_world" module.
At frontend:
http://localhost/drupal8_alpha4/hello_world
=> ok, "Hello world" text is displayed on page

At back-end
http://localhost/drupal8_alpha4/admin/structure/hello_world

so i really think that bootstrap is an incredibly easy framework to build with, and it's popular FAR beyond the drupal community

for years, people have expressed no regret using google's CDN to serve up scripts...and now bootstrap CDN offers the ability to serve up the theme and an optional swatch via CDN - which puts the whole theme into the hands of a third party.

just wondering if themers out there have opinions on this.

The goal of this project is to position All Languages as a world class Translation and Interpreting provider, with leading edge technologies to support client requirements. We want visitors to our website to become repeat customers, and have access to internal systems.

All Languages’ internal systems will be developed to add the ability to request a full quote, request a simple budgetary quote, submit a document for translation, apply for work, and update a work profile. Web pages using the website design will need to be created to present that functionality.

In doing some research for a future project, I'm trying to find out what problems are usually encountered when dealing with projects that use responsive design where Drupal is used as CMS. For example, is dealing with different screen densities a big problem for images? What other issues do you encounter when working on Drupal projects?

Thanks in advance!

First time Drupal user here. I currently have a website up and didn't want to install drupal to my live site before it was finished, so I installed it on my computer first to work on the site. I am now done building my site.

However, I am confused on how to move everything over to my server and where everything needs to go.

Currently, my site just has a Drupal log in on the front page. What am i missing?
