 A framework for trajectory optimization and optimal control for robotics based on CasADi
 
 ## Install
-pip package: ```pip install casadi-horizon```  
-conda package: ```conda install horizon -c francesco_ruscelli```
+here we assume that a mambaforge python package manager is already installed in your system. if it is not the case follow the instruction [here](https://github.com/conda-forge/miniforge#mambaforge).
+aftert installing mambaforge **assuming that you are in the project folder** you can create the environment for horizon by doing  
+
+```
+mamba env create -f environment.yml
+conda activate hori
+```
+one important dependencies of horizon is **casadi-kin-dyn**. you need to install it in the environment that you have just created (all the casadi-kin-dyn dependencies are already satisfied in the newly created environment)
+to install casadi-kin-dyn follow the instruction provided [here](https://github.com/ADVRHumanoids/casadi_kin_dyn/tree/collision)
+after installing casadi-kin-dyn you can install horizon by doing
+
+```
+pip install -e .
+```
