-# Prerequisites and Installation
-In order to edit and simulate the schematics and the layout the following tools need to be installed:
- - [xschem](http://repo.hu/projects/xschem/) - A schematic capture tool that allows to run simulations using ngspice.
- - [ngspice](http://ngspice.sourceforge.net/) - A circuit simulator.
- - [magic](http://opencircuitdesign.com/magic/index.html) - A VLSI layout tool.
- 
-After cloning this repository and installing the previous mencioned tools, the PDK form SkyWater needs to be installed. In order to do that, run the [install_pdk](install_pdk.sh) script in the repo. This script clones the following repositories:
- - [Google-Skywater 130nm Open Source PDK](https://github.com/google/skywater-pdk)
- - [Open PDK](http://opencircuitdesign.com/open_pdks/) - Standard layout files for the Google-Skywater 130nm Open Source PDK.
- - [Xschem SKY130 PDK Symbols](https://github.com/StefanSchippers/xschem_sky130) - Xschem symbol libraries for the Google-Skywater 130nm Open Source PDK.
+# PDK, Tools & Pre-requisites Intallation
+In order to get the [caravel_fulgor_opamp](https://github.com/diegohernando/caravel_fulgor_opamp) project running several tools and files need to be installed. To simplify the installation and to make sure you fullfill all the pre-requisites an [install_pdk.sh](install_pdk.sh) script is provided. To run the script just type on the console:
 
+```bash
+./install_pdk.sh
+```
+
+This script does the following:
+ - Installs all the packages needed to use the opensource tools and the [Google-Skywater 130nm Open Source PDK](https://github.com/google/skywater-pdk)
+ - Clones & installs the [Google-Skywater 130nm Open Source PDK](https://github.com/google/skywater-pdk)
+ - Installs the schematic caputre tool [XSCHEM](https://xschem.sourceforge.io/stefan/index.html)
+ - Installs XSCHEM symbol library for the Google-Skywater 130nm Open Source PDK.
+ - Installs the simualtion engine [ngspcie] (http://ngspice.sourceforge.net/)
+ - Installs the layout desing tool [magic] (http://opencircuitdesign.com/magic/index.html)
+ - Installs the layput desing tool [klayout] (https://www.klayout.de/)
+ - Installs the LVS check tool [netgen] (http://opencircuitdesign.com/netgen/index.html)
+ - Installs the [Open_PDKs] (http://opencircuitdesign.com/open_pdks/index.html)
+ - Installs the [pre-check tool] (https://github.com/efabless/open_mpw_precheck) for the Efabless/Skywater/Google [Caravel] (https://github.com/efabless/caravel) project.
