-This implementation has two methods: `Fibonacci` and `FibonacciBig`. 
+## Implementation Details
+This implementation has three methods: `Fibonacci`, `FibonacciBig` and `FibonacciFromString`. 
 
 The `Fibonacci` function is more efficient, however, it returns correct numbers between 0 and 93 (inclusive). The `FibonacciBig` function, on the other hand, is less efficient but returns practically any Fibonacci number.
+The `FibonacciFromString` function accepts the input number as a string and it can return an error if the input is not a positive number. This function is used, if the app is called from the HTTP-Server.

+# HTTP-Server for access
+
+A HTTP-Server is used to access the fibonacchi app remotely.
+The HTTP-Server can be reached on port 9090 on the path '/fibonacchi' of the server domain.
+
+If it is used on the domain https://cnoe.localtest.me, the fibonacchi value of 1000 can be calculated using the URL https://cnoe.localtest.me/fibonacci?number=1000. The app can calculate the fibonacchi number of values up to 5.000.000.
+The calculated result is displayed on the HTML page.
