 # Guia do Colaborador
 
 Algumas orientações.
+
+There are many reasons why a person or organization would want to open source a project. Some examples include:
+
+    Collaboration: Open source projects can accept changes from anybody in the world. Exercism, for example, is a programming exercise platform with over 350 contributors.
+
+    Adoption and remixing: Open source projects can be used by anyone for nearly any purpose. People can even use it to build other things. WordPress, for example, started as a fork of an existing project called b2.
+
+    Transparency: Anyone can inspect an open source project for errors or inconsistencies. Transparency matters to governments like Bulgaria or the United States, regulated industries like banking or healthcare, and security software like Let’s Encrypt.
+
+Open source isn’t just for software, either. You can open source everything from data sets to books. Check out GitHub Explore for ideas on what else you can open source.
+Does open source mean “free of charge”?
+
+One of open source’s biggest draws is that it does not cost money. “Free of charge”, however, is a byproduct of open source’s overall value.
+
+Because an open source license requires that anyone can use, modify, and share your project for nearly any purpose, projects themselves tend to be free of charge. If the project cost money to use, anyone could legally make a copy and use the free version instead.
+
+As a result, most open source projects are free, but “free of charge” is not part of the open source definition. There are ways to charge for open source projects indirectly through dual licensing or limited features, while still complying with the official definition of open source.
