-Deployment by hand
-==================
-
-The Open Build Service is flexible enough to support several deployment scenarios.
-These scenarios are described in the following (with increasing complexity).
+Deployment from git
+===================
 
+Run the absolute minimal needed backend parts:
 
-Option 1: Only use the webui
-----------------------------
+ $ cd src/backend
+ $ cp BSConfig.pm.template BSConfig.pm
+ $ su -c ./bs_srcserver
+ $ su -c ./bs_repserver
 
-If you want to work only on the Rails web frontend (webui) or running your own
-webui instance, there is no need to have an own backend server running. It is
-sufficient to start the webui with its default values. For that to work you
-have to change into its subdirectory and create the initial config like this:
+The rails root is below src/api
 
- $ cd src/webui
+ $ cd src/api
  $ cp config/database.yml.example config/database.yml
  $ cp config/options.yml.example config/options.yml
  $ rake db:setup
 
-Afterwards you can simply start the webui like this:
+Afterwards you can simply start the api and webui like this:
 
- $ ./script/server
+ $ rails s
 
 Open up your favorite browser and enter the address http://127.0.0.1:3000/
 and you should see your own Open Build Service webui instance. Thats it, actually.
 
-To speed things up a bit, you can install a local memory cache like this (as
-root in a terminal):
-
- $ zypper in memcached
- $ rcmemcached start
- $ insserv memcached
-
-You can also use Capistrano to deploy the web interface on production machines:
-
- $ cap deploy:update        - Updates the sources on the server and changes the
-                              current symlink
- $ cap deploy:migrate       - Runs database migrations
- $ cap deploy               - Updates and restarts the server
- $ cap deploy:pending       - or
- $ cap deploy:pending:diff  - will show upcoming changes
- $ cap deploy:rollback      - To get back to the previous version:

 to contribute can be found in the openSUSE wiki:

-Option 2: Setup a complete Open Build Service
-----------------------------------------
-
-In addition to the steps described above, please refer to the file
-src/backend/README. Afterwards, you have to configure your webui instance to
-use your local api instance. Have a look at the documentation in the respective
-files under src/webui/config/environments.
