+# dopey - Another Brainf**k Interpreter
+
+The dopey brainf\*\*k interpreter was created as a side project to become familiar with Python 3. The goal was to fully implement all the features of brainf\*\*k as defined in this [wiki page](https://en.wikipedia.org/wiki/Brainfuck#Language_design) into dopey.
+
+## Demo

+
+## Implemetation Limitations
+
+The dopey is limited to a memory buffer of **30,000** byte cells all initialized to zero. Any attempts to move the pointer past the bounds of the memory buffer will result in an exception being raised. Attempting to print any cell with a value outside of the defined ASCII characters may also result in an exception.
+
+## Requirements
+
+Make sure you've installed Python 3. You can download and install Python 3 at [python.org](https://www.python.org/downloads/).
+
+Verify you have Python 3 installed by running the following:
+
+```bash
+python --version
+```
+or in some systems
+```bash
+python3 --version
+```
+
+## Running dopey
+
+Clone the Github repository. From your terminal move to the root of the project and run the following line:
+
+```bash
+python dopey.py my-bf-file.bf
+```
+
+or in some systems
+
+```bash
+python3 dopey.py my-bf-file.bf
+```
