To get a Sakai 3 development instance up and running on your cmputer quickly follow these steps:

First make sure you have all the following installed on your machine:
Git version control system
Java JDK 1.5 or newer
Maven build system

Then you can set up an instance with the following Terminal commands on a Unix/Mac:

1. Create a "sakai3" folder in your home folder:
   mkdir ~/sakai3 cd ~/sakai3

2. Check out the latest Nakamura code. This will create an "open-experiments" folder
   git clone git://github.com/ieb/open-experiments.git cd open-experiments/slingtests/osgikernel

3. Check which stable tags are available:
   git tag

4. Check out and switch to the latest stable tag (0.4 in this case):
   git co -b 0.4 This is not required, you can also stay at bleeding edge by omitting this step.

5. Open up the "slingtests/osgikernel" folder and build the kernel:
   cd slingtests/osgikernel mvn clean install

6. Start the kernel:
   tools/clean_restart.sh

7. Open a browser and type "http://localhost:8080/dev" into the address bar

Done. Now you have a the latest stable kernel with latest stable UX code (from Maven repo) running on your local machine.

If you would like to do UI/UX development you will need to additionally to the following:

1 Switch to the previously created "sakai3" folder in your home folder
cd ~/sakai3

2. Check out the UX code from Github, this will create a "3akai-ux" folder:
   git clone [email protected]:sakaiproject/3akai-ux.git

3. Go to the kernel's Felix console by typing the following address into the browser's address bar (preferably with an alternative browser from the one you are using from development):
   "http://localhost:8080/system/console"

4. Log in using "admin" for username and password

5. Select the "Configuration" tab on the top part of the console

6. Open up the "Apache Sling Filesystem Resource Provider" module`s window (towards bottom of page)

7. Enter "/dev" in Provider Root field, enter the path to the "dev" folder in you checked out UX code to "Filesystem Root" field , and click "Save"

8. Open up the "Apache Sling Filesystem Resource Provider" again

9. Enter "/devwidgets" in Provider Root field, enter the path to the "devwidgets" folder in you checked out UX code to "Filesystem Root" field , and click "Save"

Done. Now if you go to "http://localhost:8080/dev" the kernel should load the files from your local machine, from the paths you`ve specified earlier.
You should be able to start modifying files and see changes in browser.
