 ## Introduction
 
-Geo SAM is a tool aims to help people segment, delineate or label landforms with large-size geo-spatial raster images.
-Segment Anything Model (SAM) is foundation AI vision model with super power, but the model size is large and using it to process images can take a long time, and a modern GPU is usually needed.
-With the pre-generated image features using Vision Transformer image encoder, the interactive segmentation process can be run in real-time on a laptop without dedicated GPU.

 ## Installation
 
 ### Install QGIS
 
-You are recommended to install the latest version of QGIS, since the plugin has only been tested on the versions later than QGIS 3.30, at least ver. 2.28 is recommended.
