 # Development Setup
 
-## Requirements
+## Prerequisites (Requirements)
 
-- Python: `^3.10`
-- Poetry: `1.2`
+- Python: `>=3.10`
+- [Mamba](https://github.com/conda-forge/miniforge#install): `>=1.4`
 - Node: `>=14`
-- Redis: `^7.0`
-- Postgres: `^15.0`
-- zbar
-  - Mac OS X: `brew install zbar`
-  - Debian derivatives: `sudo apt-get install libzbar0`
-  - Fedora: `sudo dnf install zbar-devel`
-  - Windows: DLLs are included with the Windows Python wheels
-- GDAL: `>=3.4.1, <3.5`

-This project uses [Poetry](https://python-poetry.org/docs/) for packaging and dependencies management. Please make sure it is installed on your system.
-[ZBar](https://zbar.sourceforge.net/) is used to detect and decode QR-Codes and need to be installed on the system as well.
+
+This project uses [Mamba](https://github.com/mamba-org/mamba) for environment and dependencies management. Please make sure it is installed on your system.
+
+> Actually, Mamba and Poetry together are used to manage environment and dependencies. But only Mamba is required to be present on the System. Poetry will be installed by Mamba. Mamba installs pre built binaries for depedencies like GDAL. Poetry installs the rest of the Python dependencies.
 
 ## Installation
 
 ### Python Package
 
 ```bash
-# Git clone repository
-# these versions have to be fixed for now, since poetry and (py)gdal packages can't work together
-poetry run pip install numpy==1.23.5
-poetry run pip install pygdal==3.4.1.10
-poetry install
-poetry shell  # Spawns a shell within the virtual environment
-pre-commit install  # Install pre-commit hooks
-npm install # Install local versions of esbuild, eslint and stylelint to build and check JS and CSS
-# Hack away
+git clone https://github.com/GIScience/sketch-map-tool.git
+cd sketch-map-tool
+mamba env create --file environment.yml
+mamba activate smt
+poetry install  # poetry installs directly into activated mamba environment
+pre-commit install
+# install local versions of esbuild, eslint and stylelint to build and check JS and CSS
+npm install
+# hack away
 ```
