+The easiest ways to setup an environment with everything we need is to follow only one of the following two options:

+- [Creating a conda environment](#conda-environment)
+- [Using the robotology-superbuild](#installation-via-robotology-superbuild)
 
-- Using the robotology-superbuild
-- Creating a conda environment
 
 ### Conda environment
 
 #### Install a conda distribution
 
-If you do not have one, please install a conda distribution. We suggest to use the minimal [mambaforge](https://github.com/conda-forge/miniforge#mambaforge) distribution, which uses conda-forge packages by default and installs the [mamba](https://github.com/mamba-org/mamba) command by default.

 #### Create an environment
 
 Then create the following environment with all the packages needed:
 
-```bash
-mamba create -c conda-forge -c robotology -n ergocub-gz
-```
+~~~bash
+conda create -n ergocub-gz libgz-sim-yarp-plugins ergocub-software
+~~~
 
-Then, activate the environment we created with:
+Once you did this, you can activate it with:
 
-```bash
-mamba activate ergocub-gz
-```
-
-and finally, install in it the packages we need:
-
-```bash
-mamba install libgz-sim-yarp-plugins ergocub-software
-```
+~~~bash
+conda activate ergocub-gz

 ### Installation via robotology-superbuild
 
-[robotology-superbuild](https://github.com/robotology/robotology-superbuild/tree/master) is a meta repository that is able to download and compile a plethora of software from the [robotology](https://github.com/robotology) organization.
