 ## Installation
 
-From go:
+### go install (recommended)
 
 ```shell
 go install github.com/sammcj/gollama@HEAD
 ```
 
-From Github:
+### curl
+
+I don't recommend this method as it's not as easy to update, but you can use the following command:
+
+```shell
+curl -sL https://raw.githubusercontent.com/sammcj/gollama/refs/heads/main/scripts/install.sh | bash
+```
+
+### Manually
 
 Download the most recent release from the [releases page](https://github.com/sammcj/gollama/releases) and extract the binary to a directory in your PATH.
