# Overview

As stated previously the working directory for server-common installation is **edu.harvard.i2b2.server-common folder**. The following outlines the steps that need to be taken during the configuration stage of the installation.

**Step 1:**   Change your woking directory

**Step 2:**   Configure the build properties

### Assumptions

The steps in this section are based on the following assumptions:

**Linux:** your user has the appropriate ***administrative access*** to the opt directory.

**Windows:** You are logged into the Windows Command Prompt as an ***Administrator***.

If you do not have the appropriate access you will have problems running the scripts.

### Step 1: Change working directory

The **first step** in the cell configuration process is to change your working directory to the location of your **edu.harvard.i2b2.pm folder**.

  **Change Directory Command**

CD *YOUR_I2B2_SRC_DIR*\edu.harvard.i2b2.server-common

Important

The change directory command shown above is written for Windows. The command itself is the same for both Linux and Windows with the only exceptions being the slashes in the path name and Linux does not include the "drive".

- *Linux Path:* use a forward slash.
- *Windows Path:* use a backward slash.

***EXAMPLES:***

***Linux Command:***  CD /opt/i2b2/edu.harvard.i2b2.server-common

***Windows Command:***  CD C:\opt\i2b2\edu.harvard.i2b2.server-common
