+## Lesson 01
+
+#### Prequisites
+- Classes
+- Functions
+
+#### Files
+- _components/Point.cpp_
+- _components/Point.h_
+- _main.cpp_
+
+#### Task
+1) With the point-class we represent a single dot on screen, giving it a position and character as "image". Begin by inspecting _components/Point.h_ and _components/Point.cpp_ and figure out what a header (.h) and code (.cpp) file contain and how they differ.
+2) When an instance of a class in C++ is created, its constructor is used to initialize values. At some point, the created instance will get destroyed which uses the destructor. Read about these two and implement them in _components/Point.cpp_.
+3) Select to call __mainL01__ in __main__ of _main.cpp_ and think or read about the purpose of this function as the applications entry point.
+4) See what happens when you run the application now and play around with the point or maybe create multiple. You can also modify the destructor to do something special (like print to the command line).
+5) Go to _components/Point.*_ again and look at the member variables x,y and img. Notice that they are defined in a "private" region. Try to modify these directly in the main function __mainL01__. If that does not work, you can implement the getters and setters marked with TODO in _components/Point.cpp_
+6) Continue exploring around with the point and see what happens.
+
+Once you're ready, you can _git merge lesson02_.
