 ## Project Overview
 
-This repository contains our efforts for creating a Python based C extention image enhance library. As the first part of the project a python-compatibile library will be implemented, containing various functionalities from the area of Image Processing and Manipulation.

-The calculations are going to be performed within c++ code, with the extention bridging the gap between languages, allowing for full acces within the Python environment while utilizing the computational speed of low-level language.

-Further on, we plan on displaying the capabilities of developed extension with a python-based User Interface or Pipeline for Image Manipulation and  Image Processing, allowing user to utilize the functionalities from the level of a command line or a Graphic Interface Upload-Manipulate-Output tool.

 ## Used tools and dependencies
 
-The project requires:
+The project contains the `app` python package. Short for Advanced-Python-Programming.
+
+The package requires the following configuration in order to be properly installed (see later sections):
 
 - Python 3.13
 - CPython implementation
+- numpy 2.3.5
+
+### Installation Guide
+
+The package can be installed with two dependencies bundles:
+- baseline package dependencies intended for end user.
+- development dependencies used to test, build the project (requires additional installations).
+
+Our package uses the `setuptools` backend.
+
+#### Prerequisites
+
+Create python environment using `venv`:
+
+```bash
+python3 -m venv .venv
+```
+
+Next, you need to choose one of the dependencies bundles.
+
+#### End user package installation:
+
+Run the following commands in your terminal and install the `app` package:
 
 ```bash
 pip3 install -e .
 ```
- will install following packages for end user:
 
-numpy 2.3.5
+Alternatively previous step  can be accomplished using by running the `Makefile` command:
+
+```bash
+make python-install
+```
+
+####
+Package with development dependencies installation:
 
 ```bash
 pip3 install -e .[developement]
 ```
 
+It is not needed to install the package in editable mode (`-e` flag).
+However, if one would want to do code modification, the option is very helpful.
+
+And using makefile:
+
+```bash
+make python-install-editable
+```
+
+### Dependencies
+
+See also `setup.cfg` for more details.
