# 1.2.1 Extract Source Code

In the *[Requirements](https://i2b2.atlassian.net/wiki/display/getstarted/2.6+i2b2+Requirements) Chapter* of this install document you downloaded a zip file that contained the i2b2 Web Client code. This zip file contains all the i2b2 code needed to install the i2b2 Web Client on your web server.

### Steps to extract the code

1. Set up a target source directory for the contents of the web client zip file .

2. Locate the **i2b2webclient.zip** file you downloaded in the *Requirements chapter*.

3. Extract the web client code into the target source directory you just created.

Tip

You will want to make note of the location as it will be needed further along in the i2b2 installation. In the installation document whenever you see **YOUR_I2B2_WC_DIR** it will need to be replaced with the location of your i2b2 Web Client code.

For your convenience an installation Worksheet to track the setup locations has been provided in the Appendices Chapter.
