 ### Variables Addition
 
 There are 2 types of variables:
 * Global variables: All of the 5 programs can access it.
 * Local variables: Only one program has access to it.
 
 #### Global Variable

+### Library Management
+
+In contrast to the conventional Arduino IDE, the PLC IDE manages the library add-on and usage differently. To add the desired library, go to **Resources** tab and click the **Libraries** listed under the **Sketch**.
+
+![Adding a library to the PLC IDE Arduino Sketch](assets/plcide-library-management.gif)
+
+With the 'Sketch Libraries' window open, click the **Add** option and fill out the library name. You will have to fill in the needed library version as well.
+
+For example, if you want to add the 1.1.1 version of the 'Arduino_MachineControl' library, respective information must be introduced to its fields accordingly.
+
+It is possible to find this information using the [Arduino Library List](https://www.arduinolibraries.info/) or referencing the indexed library on your development environment if you have downloaded it to use within Arduino IDE. By navigating manually to the local libraries directory on your development environment, you can access the meta-data from the 'library.properties' of the desired library.
+
+***Currently only publicly available libraries can be added to the PLC IDE Arduino Sketch, and you can check its availability by searching in the [Arduino Library List](https://www.arduinolibraries.info/).***
+
+Once you have followed the previous steps, the libraries will be available for use. A library of choice can be removed by clicking on the **Remove** option within the 'Sketch Libraries' window.

 ### Ladder Diagram
+
 This programming environment is based on lines and blocks, a line has a path from left to right that needs to pass all the in between blocks in order to continue towards the right, if it does pass all the different blocks (like AND gates) it will end on the right on a brackets symbol (coil) triggering whatever you have set up to do, which could be for example a relay latching to Normally-Open (NO).

 ### Sequential Function Chart
+
 This language approaches the script in a similar way as a flowchart, meaning you have blocks that do some work, you check the result of that work, and afterward you keep flowing with the choices.
 
 SFC language can not interact directly with the machine, meaning you can not make an output be OFF directly, to do so you will need to create **actions**
 
 #### Actions
+
 An action is a script in another language (i.e. structured text) that performs the work, this will get triggered depending on the chart.
 
 To create one go to your project tree, right-click the SFC script and click the "New action" button.
