 ## 1. How to use this library
 
-This library is intended to be used as a git submodule inside a git version controlled KiCAD project.
+This library can be used in two different ways. It can be used in a central position (centralized) or as part of the project (git submodule).
 
-### 1.1 Adding the library to your KiCAD Project
+### 1.1 Linking the library to your KiCad Project
 
-Go to the desired directory where you want to place the library submodule inside your project. Ther you add KicED as submodule with the following comand.
+The KicED library is intended to be linked relative to your KiCad project. This means, that you will not have absolute library links which are highly specific to each user. This can create problems when collaborating together. The KicED tools allows you to avoid this problem and work wherever you want in your directory. The only thing which must be defined in your project is the location of KicED relative to the KiCad project you are working on. This is all done by using the [KiCad environment variable](https://docs.kicad.org/7.0/en/kicad/kicad.html#kicad-environment-variables) ```${KIPRJMOD}\<...>```.
+#### 1.1.1 As Git Submodule
+
+Go to the desired directory where you want to place the library inside your project. There you add KicED as submodule with the following comand.
 
 ```console
 git submodule add https://git.keydev.me/Kerem/KicED
 ```
+
+Then go into the folder ```KicED\project_init_tool```. In this folder execute the KicED library linker tool by executing the follwing command.
+
+```console
+python KicED_libLinker.py
+```
+There follow the instructions given by the tool. Once completed successfully there should be the files ```fp-lib-table``` and ```sym-lib-table```created besides your KiCad ```*.kicad_pro``` project file. These files will be recognized by KiCad as project specific libraries and contain all the relative linkages to the KicED library.
+
 Then open your KiCAD project and go to ```Preferences```in the top left corner and select ```Manage Symbol Libraries...```.

 ### Centralized (deztached from the KiCAD Project)
 
 Library is plced at a centralized point. Best place is the besides the KiCAD projects. This saves data redundancy when working on multiple KiCAD projects.
