 ## Installation
 
 DeciMojo is available in the [modular-community](https://repo.prefix.dev/modular-community) package repository. You can install it using any of these methods:
 
 From the `pixi` CLI, simply run ```pixi add decimojo```. This fetches the latest version and makes it immediately available for import.
 
-For projects with a `mojoproject.toml`file, add the dependency ```decimojo = ">=0.3.1"```. Then run `pixi install` to download and install the package.
+For projects with a `mojoproject.toml`file, add the dependency ```decimojo = "==0.4.0"```. Then run `pixi install` to download and install the package.
 
 For the latest development version, clone the [GitHub repository](https://github.com/forfudan/decimojo) and build the package locally.
