 Usage
 -----
-The `zimfw` plugin manager builds an initialization script, at `${ZIM_HOME}/init.zsh`,
-that initializes the modules you defined in your `~/.zimrc` file.
+The `zimfw` plugin manager installs your modules at `${ZIM_HOME}/modules`, and
+builds a static script at `${ZIM_HOME}/init.zsh` that will initialize them. Your
+modules are defined in your `~/.zimrc` file.
 
 The `~/.zimrc` file must contain a `zmodule` call for each module you want to
 use. The modules will be initialized in the order they are defined.
