 # FindInPi
-A Kotlin HTTP API to searching pi for specific strings of numbers. Includes a pure kotlin and C/JNI/kotlin impelemntation.
+A Kotlin HTTP API for searching Pi for specific series of numbers. Includes both pure Kotlin and C/JNI/Kotlin impelemntations.
 
 ## Why?
-Pi is probably the most famous irrational number. As an irrational number, when pi is represented as a decimal it is a never ending, never permanently repeating, seemingly random stream of numbers.
+Pi is the world's most famous irrational number. As an irrational number, Pi is a never ending, never permanently repeating, seemingly random stream of numbers when represented as a decimal.
 
-Pi has long been popular to calculate to many digits using computers, with the world record at the time of this writing being over 100 trillion digits.
+Pi has long been a popular reference number by which to calculate numbers to many digits using computers, with the world record at the time of this writing being over 100 trillion digits.
 
-A random number number this long contains many other smaller numbers, such as your social securty number, phone number, birthday, etc. These numbers occur by chance, but it can still be interesting to see exactly where in pi some of these numbers might occur.

-Let's use phone numbers as an example. US phone numbers are 10 digits long, so there are 10<sup>10</sup> possible phone numbers. If we were to randomly generate 10<sup>10</sup> 10-digit numbers, the resulting set should contain nearly all possible values. Following this we can see that in any random string of digits, if we want to find any decimal number of length n, our string of digits must be 10<sup>n</sup> * n digits long. So in our example we'd need 10<sup>10</sup> * 10 digits of pi, or 100 billion digits.

-You download some 1B+ digit calculations of pi from [here](https://stuff.mit.edu/afs/sipb/contrib/pi/), 
-or you can calculate your own pi data file with [y-cruncher](http://www.numberworld.org/y-cruncher/), or you

 ### Usage
-To use the HTTP API once running:
+After you run the program, use the HTTP API:
 ```shell
 $ curl --request POST \
      --header 'Content-Type: application/json' \
      --url 'http://localhost:8080/search' \
      --data '{"searchText":"62643"}'
