 # Why does open-source matter so much?
 
-Open Source gives you freedom.
-You know everything about the TERES-I laptop. 
+Proprietary, closed-source products:
+
+- do not come with source code
+- provide no access to the board's design layout
+- do not allow users to easily add the functionality that they want
+- do not allow users to modify what they don't like
+- generally make it difficult (or impossible) to repair your own product
+
+On the other hand, open-source projects provide:
+
+## Transparency
+
+Most complex hardware projects are closed-source (i.e. black box) and you may only indirectly infer how components are connected or how things operate in general.
+Open-source products transparency and freedom to know as much as possible about the products you and others enjoy.
+You are able to review and modify open-source software.
+You have full access to both the hardware and the software components and you are able to control every bit of your laptop.
+You don't even have to purchase anything to access these resources; you can use our work (or parts of it) as a basis for existing projects.
+
+## Freedom To Modify
+
+Open-source hardware allows you and others to tailor the PCBs according to user needs.
+For example, you are able to add more processors, memories, etc.
+
+It also gives you independence and self-sufficiency.
+If a problem arises (any problem!), you have the freedom to fix it.
+
+We provide the hardware design files and schematics for the TERES-I laptop.
+The hardware design is made with an open-source CAD tool called KiCad.
+
+## Peace Of Mind
+
+There is nothing hidden or "fine print" for you to worry about.
+No lawyers will chase after you for using this material for personal or commercial use.
+(Check the license for further information.)
+
+## Ease Of Use
 
-We provide the hardware design files and schematics.
-The hardware design is made with open CAD tool.
-Nothing is hidden.
 The sources for the Linux distribution and step-by-step compilation instructions are available and easily accessible.
-You have full access to both the hardware and the software parts and you are able to control every bit of your laptop.
-You don't even have to purchase anything to access these resources – you can use our work (or parts of it) as a basis for own projects already.
+Documentation can behave as living documents - aggregated reference materials to solve a veriety of uncertainties.
 
-The educational value of such a product is high.
-Most complex hardware projects are closed and you can only indirectly guess how things are connected or how things are operating in general.
+## Education
+
+There is great educational value of open-source products, inherent in the availability of materials to study.
+
+## Support
+
+You don't have to count only on the availability of the technical support.
+Don't like the way something works, have an idea for an improvement, or think the documentation sucks?
+You can improve it yourself or ask others to help!
+
+## Longevity
 
 Open source gives guarantee for longevity.
-It also gives you independence and self-sufficiency – if a problem appears you have the freedom to fix it.
-You don't have to count only on the availability of the technical support.
-Proprietary, closed-source products: do not come with source code; provide no access to the board's design layout; cannot easily add the functionality that you want; cannot modify what you don't like; no opportunity to repair your own product.
+Contributors may fork the project, make improvements, and merge those improvements back into the main project to benefit everyone.
+There is no concern that a company goes bankrupt and the products disappear.
