+In this repository we are presenting the **SAS Packages Framework** which allows to develop and use SAS packages. The latest version of SPF is **`20241207`**.
 
 **To get started with SAS Packages** try this [**`Getting Started with SAS Packages`**](https://github.com/yabwon/SAS_PACKAGES/blob/main/SPF/Documentation/Getting_Started_with_SAS_Packages.pdf "Getting Started with SAS Packages") presentation (see the `./SPF/Documentation` directory).
 
 **The documentation and more advance reading** would be the [**`SAS(r) packages - the way to share (a how to)- Paper 4725-2020 - extended.pdf`**](https://github.com/yabwon/SAS_PACKAGES/blob/main/SPF/Documentation/SAS(r)%20packages%20-%20the%20way%20to%20share%20(a%20how%20to)-%20Paper%204725-2020%20-%20extended.pdf "SAS packages - the way to share") article (see the `./SPF/Documentation` directory).
 
-
 *Note:* Filenames references `packages` and `package` are **reserved keywords.**
 The first one should be used to point local folder with packages and the framework.
 The second is used internally by macros.
 After assigning the directory do not change them when using the SPF since it may affect stability of the framework.
