 HAVE FUN USING IT!
+
+Little explanantion: 
+
+to start, we need a main-function.
+```
+haupt
+anfang
+
+ende
+```
+
+Inside of this, we can use many commands...
+Example: ```schreiben ``` </br>
+This command writes to the terminal.
+
+We use it like this: 
+```
+schreiben ("HELLO" + " " + "World" + nZeile)
+```
+
+You can concatenate as many strings, escape-sequences (nZeile) or Variables as needed...
+```
+nZeile
+```
+appends a new Line to the written Text.
+
+
+To add a new Variable, we need to do so before the first function has been created.
+
+```
+neuevariable (Hallo = "HELLO") //Adds a new Variable //The compiler recognizes the type of Variable
+//strings need to be encapsulated in Quotes
+
+
+haupt //The main-function
+anfang
+    schreiben (Hallo + nzeile)
+    Hallo =+1 //Is round about the same as the ++ operator in C++
+    schreiben (Hallo + nZeile)
+ende
+```
+If we want the user to be able to input a value for the Variable, we can do this...
+```
+neuevariable (Hallo = 123) //This time, we create a Number-variable. 
+
+haupt
+anfang
+    schreiben (Hallo + nZeile)
+    eingeben (Hallo)
+    schreiben (Hallo + nZeile)    
+ende
+```
+
+This inputs the variable; It also pays attention, the user didn't input anything wrong like  
+
+→Too long numbers (in case of Numbers)
+→Characters (in case of Numbers) 
+
+Now, by that, we can create a new Function.
+```
+prototyp (writeHello) //Creates the function-prototype
+
+haupt
+anfang //This is the same as the begin...end indentation-block in Pascal... In c++ it would be {...}
+    aufrufen (writeHello)
+ende
+
+leer writeHello
+anfang
+schreiben ("Hello World" + nZeile)
+ende
+```
+This creates a function. To call the function, we use the command ```aufrufen```
+
+Inside of functions, we can also do comparisons...
+```
+prototyp (test)
+neuevariable (var1 = "3") //comparisons with Numbers need to be tested...
+
+leer test
+anfang
+    wenn var1 == "3"
+    anfang
+       schreiben (Hello ;-))
+    ende
+ende
+
+haupt
+anfang
+   aufrufen (test) //it should write 'Hello', because var 1 equals to "1"
+ende
+```
+
+You can compare almost everytype of Variables, but can't concatenate...
+Theres also a goto() function.
+```
+haupt
+anfang
+    punktsetzen (s1) //places the goto-point
+    schreiben ("HI" + nZeile)
+    gehezu (s1) //goes to s1... It will write infinitely HI
+ende
+```
