 # Handwriting OCR
+[![Code style: black](https://img.shields.io/badge/code%20style-black-000000.svg)](https://github.com/psf/black)

 The project tries to create software for recognition of a handwritten text from photos (also for Czech language). It uses computer vision and machine learning. And it experiments with different approaches to the problem. It started as a school project which I got a chance to present on Intel ISEF 2018.

 ## Getting Started
 ### 1. Clone the repository
-```
+```bash
 git clone https://github.com/Breta01/handwriting-ocr.git
 ```
 After downloading the repo, you have to download the datasets and models (for more info look into [data](data/) and [models](models/) folders).
 
 ### 2. Requirements
-The project is created using Python 3.6 with Jupyter Notebook. I recommend using Anaconda. If you have it, you can run the installation as:
+```bash
+make bootstrap
 ```
-conda create --name ocr-env --file environment.yml
-conda activate ocr-env
+The project is using Python 3.7 with Jupyter Notebook. I recommend using virtualenv. Running command `make bootstrap` should install all necessary packages. If you have it, you can run the installation as:
+
+Main libraries (all required libraries are in [requirements.txt](requirements.txt) and [requirements-dev.txt](requirements-dev.txt)):
+* Numpy
+* Tensorflow
+* OpenCV
+* Pandas
+* Matplotlib
+
+### Activate and Run
+```bash
+source venv/bin/activate
 ```
-Main libraries (all required libraries are in [environment.yml](environment.yml)):
-* Numpy (1.13)
-* Tensorflow (1.4)
-* OpenCV (3.1)
-* Pandas (0.21)
-* Matplotlib (2.1)
