# Setting up an API baseline

Once your plug-in is converted to use API Tools, you need to set up a baseline in order to get the compatibility analysis performed for your plug-in.

To create an API baseline do the following:

1. Open the Plug-in Development > API Baselines preference page.
2. Select the Add Baseline... button to open the API baseline wizard.
   - Give a meaningful name for your baseline
   - Click Browse... and select the root folder of the Eclipse SDK you want to choose as your baseline
   - Click OK in the folder dialog
   - Once the baseline is initialized, click Finish
3. Click OK and you are all set. If your workspace contains some existing projects, you will be prompted for a rebuild.
