+# **BF-it**
+A compiler from a C-like language to Brainfuck
+
+Always heard that Brainfuck is Turing complete but still had doubts about its computational power?
+Those days are over
+
+
+## What is this?
+BF-it is a Compiler of a C-like language to Brainfuck, written in Python
+
+You give it C-like code, and it gives you Brainfuck code with the same functionality :)
+
+
+## Why did you create it?
+There are several reasons why I chose to create this
+
+1. I always heard that Brainfuck is Turing complete, and
+   therefore as strong as any other language
+    * I wanted to put that to the test, and find a concrete
+      proof that it is true
+2. I find it beautiful how a seemingly bunch of nonsense
+   characters can have a logical meaning / functionality
+    * I wanted to take it to the extreme
+3. I wanted to practice my developing skills
+4. It seemed to be like a real challenge (and it was!)
+5. But mostly, and most importantly, I did it for teh lulz
+
+
+## What can I use it for?
+Create a Brainfuck code of your choice, send it to your friends, and tell them to run it (on some online interpreter, for example)
+
+When they receive a bunch of nonsense which does something meaningful, they will (maybe) be amazed
+
+
+## How do I use it?
+
+1. Write a C-like code (example programs included) into a file
+2. Open your favorite command line interface
+3. Run `BF-it.py <path_to_code_file>`
+    * This will compile your file and create a .bf file with
+      Brainfuck code
+    * (optional parameters: `-o` for output file, and `-r`
+      for running the compiled file)
+4. Run `Interpreter.py <path_to_bf_file>`, this will execute
+   the Brainfuck code
+
+Example:
+```
+$ cat helloworld.code
+int main()
+{
+    print("Hello World!\n");
+}
+
+$ ./BF-it.py helloworld.code
+Compiling file 'helloworld.code'...
+Compiled successfully to 'helloworld.bf'
+$ cat helloworld.bf
+>[-]>[-]<>++++++++[-<+++++++++>]<.>++++[-<+++++++>]
+<+.+++++++..+++.>++++++[-<------------->]<-.>+++++[
+-<+++++++++++>]<.>++++[-<++++++>]<.+++.------.-----
+---.>++++++[-<----------->]<-.>+++[-<------->]<--.<
+
+$ ./Interpreter.py helloworld.bf
+Hello World!
+```
+
+For a more interesting example, check out Tic-Tac-Toe!
+
+<img alt="Tic-Tac-Toe" src="images/tic tac toe.gif?sanitize=true"><br/>
+
+1. Take a look at tic_tac_toe.code in the 'examples/games' directory
+2. Run ```./BF-it.py examples/games/tic_tac_toe.code -r```
+3. Play around
+4. If you're brave, take a look at the generated Brainfuck code
+5. If you're very brave, try to understand it (I can't)
+
+## How do I write code?
+Please refer to the 'examples' directory.
+It contains examples and explanations for syntax, operations, flow, and more
+
+
+## I would like to add a feature / fix a bug
+If you would like to add a feature yourself, perform a pull request and add your changes. I will review them
+
+If you found a bug, or have an idea for a feature, open an issue
