1. Get the latest release of Blender and install it.
2. Download TheGrovePackage.zip and unzip it.
3. Inside you will find TheGroveAddon.zip – keep this file as it is and do not unzip it.
4. Launch Blender and in the user preferences go to the Add-ons section.
5. Click Install… Browse to your download location, select TheGroveAddon.zip and install it.
6. Search the list for The Grove. If it’s not there, you installed the incorrect file – please go back and carefully read steps 2 and 3.
7. Check the box to enable the add-on. Click the little triangle to reveal The Grove’s settings.
8. Let The Grove know where to find your twigs and textures. You can download twigs and textures to anywhere you like, and then point The Grove to your these folders.
9. Save your user settings to keep The Grove enabled next time you start Blender.

Close the Preferences window. Open up the 3D view sidebar from the View menu (or simply press N to toggle it). The tool shelf opens next to the 3D view. Switch to the tab named “The Grove”. Add a new grove and simply hit “Grow” to start and have fun growing!

Be sure to back up your downloaded copy of The Grove Add-on for the future. After installing an update of Blender, it might be necessary to repeat the above steps. If all went well, start growing with the Quick Start guide. If you have trouble installing, please let me know.
