 To update avalanche to the latest version, uninstall the package with `pip uninstall avalanche-lib` and then execute again the pip install command.
 
-## 🐍 Install the Master Branch Using Anaconda
-
-We suggest you to use the _pip package_, but if you need some recent features you may want to install directly from the **master branch**. In general, the master branch is well tested and safe to use. However, the API of new features may change more frequently or break backward compatibility. _Reproducibility is also easier if you use the pip package._
-
-```bash
-# choose your python version
-python="3.8"
-
-# Step 1
-git clone https://github.com/ContinualAI/avalanche.git
-cd avalanche
-conda create -n avalanche-env python=$python -c conda-forge
-conda activate avalanche-env
-
-# Step 2
-# Istall Pytorch with Conda (instructions here: https://pytorch.org/)
-
-# Step 3
-conda env update --file environment.yml
-```
-
-{% hint style="info" %}
-On **Linux**, alternatively, you can simply run the `install_environment.sh` in the _Avalanche_ home directory. The script takes 2 arguments: `--python` and `--cuda_version`. Check `--help` for details.
-{% endhint %}
-
-You can test your installation by running the `examples/test_install.py` script. Make sure to include avalanche into your **$PYTHONPATH** if you are running examples with the command line interface.
-
 ## 💻 Developer Mode Install
 
-If you want to expand _Avalanche_ and help us improve it (see the "[_From Zero to Hero_](../from-zero-to-hero-tutorial/03\_benchmarks.md)" Tutorial). In this case we suggest to create an environment in _**developer-mode**_ as follows (just a couple of more dependencies will be installed).
-
-Assuming you have **Anaconda (or Miniconda) installed** on your system, you can follow these simple steps:
-
-1. Install the `avalanche-dev-env` environment and activate it.
-2. [Install Pytorch + TorchVision](https://pytorch.org) (follow the instructions on the website to use conda).
-3. Update the Conda Environment.
-
-These three steps can be accomplished with the following lines of code:
-
-```bash
-# choose you python version
-python="3.8"
-
-# Step 1
-git clone https://github.com/ContinualAI/avalanche.git
-cd avalanche
-conda create -n avalanche-dev-env python=$python -c conda-forge
-conda activate avalanche-dev-env
-
-# Step 2
-# Istall Pytorch with Conda (instructions here: https://pytorch.org/)
-
-# Step 3
-conda env update --file environment-dev.yml
-```

-You can test your installation by running the `examples/test_install.py` script. Make sure to include avalanche into your **$PYTHONPATH** if you are running examples with the command line interface.
+```pip install -e ".[dev]"```
 
-That's it. now we have _Avalanche_ up and running and we can start contribute to it!
+This will install in editable mode, so that you can develop and modify the installed Avalanche package. It will also install the "extra" dev dependencies necessary to run tests and build the documentation.
