- Create a new Chrome profile for running your Helena programs. (See directions here.)
- In the new Chrome profile, install the extension from the Chrome Web Store. (Press the "Add to Chrome" button.)
- You're all set! Helena is installed, and you can click the new icon at the upper right to open the Helena control panel.
If you're a developer and you might want to modify how Helena works, you may prefer to follow the installation instructions for developers.
Once you've installed the Chrome extension, the tutorial has some resources for learning how to use it.
