# Updating a plug-in [edit]

This page describes how to update the version of a plug-in that you have installed into Eclipse or Aptana.

## Introduction

After you've installed a plug-in, such as RadRails, into Aptana or Eclipse, you can update the version of your plug-in when an update is released.

You have the option of updating to a specific plug-in build by using a policy file. If you do not use a policy file, you can do a general update by following the instructions in Updating a version of a plug-in below.

## Instructions

To use a policy file to update to a specific build:

1. From the Window menu in Aptana or Eclipse, select Preferences... to open a Preferences window.
2. From the tree on the left side of the Preferences window, select Install/Update.
3. In the Policy URL field, type or paste the policy URL for the build update that you want to install.
4. Click OK.
5. To install the update that you just specified, follow the instructions below for updating a version of a plug-in.
