 The most common usage of environments is to create a new [_explicit_ environment](https://docs.julialang.org/en/v1/manual/code-loading/#Environments) for a project in a directory. This creates a `Project.toml` file in the directory that specifies the dependencies for the project and a `Manifest.toml` file that specifies the exact versions of the dependencies, and their underlying dependencies. We'll discuss how to set up a new environment for a project in the [REPL section](#using-the-julia-repl).
 
-Julia environments can be [stacked](https://docs.julialang.org/en/v1/manual/code-loading/#Environment-stacks). This means that you can have a _primary_ environment that is used by default, and then _secondary_ environments that are used when you activate them. This is useful when you want common packages to be available to all projects, but also want to isolate projects from each other.
+Julia environments can be [stacked](https://docs.julialang.org/en/v1/manual/code-loading/#Environment-stacks). This means that you can have a _primary_ environment embedded in the stacked environment, along with _secondary_ environment(s) that define common packages to be available to many projects.
 
-Most commonly the environment for a Julia installation is the primary environment, and you can add packages to this environment that you want to be available to all projects as we'll show in the [REPL section](#using-the-julia-repl).
+From a project development point of view, most commonly the project environment will be the primary environment, isolated from other project environments. And the environment of the Julia version installation (e.g. the `@v1.10` env) will be a secondary environment because its in the default `LOAD_PATH` [Julia environmental variable](https://docs.julialang.org/en/v1/manual/environment-variables/#Environment-Variables). You can add packages to the Julia version environment that you want to be available to all projects as we'll show in the [REPL section](#using-the-julia-repl).
