 ## Basic Installation
 
-<!-- The simplest way to install the Parcels code is to use Anaconda and the [Parcels conda-forge package](https://anaconda.org/conda-forge/parcels) with the latest release of Parcels. This package will automatically install all the requirements for a fully functional installation of Parcels. This is the "batteries-included" solution probably suitable for most users. Note that we support Python 3.10 and higher.

-If you want to install the latest development version of Parcels and work with features that have not yet been officially released, you can follow the instructions for a [developer installation](#installation-for-developers).
+If you want to install the latest development version of Parcels and work with features that have not yet been officially released, you can follow the instructions in the [development section in our contributing guide](../../development/index.md#development).
 
 The steps below are the installation instructions for Linux, macOS and Windows.
 
 (step-1-above)=
 
-**Step 1:** Install Anaconda's Miniconda following the steps at https://docs.anaconda.com/miniconda/. If you're on Linux /macOS, the following assumes that you installed Miniconda to your home directory.

-**Step 2:** Start a terminal (Linux / macOS) or the Anaconda prompt (Windows). Activate the `base` environment of your Miniconda and create an environment containing Parcels, all its essential dependencies, `trajan` (a trajectory plotting dependency used in the notebooks) and the nice-to-have cartopy and jupyter packages: -->

-Parcels v4 is in active development.
-
-A pre-release version of Parcels (i.e., the latest version on `main`) can be installed via conda using the following instructions (which creates an environment `parcelsv4-env`, activates it, installs Parcels from a custom pre-release channel that we're using, and installs some additional helper packages).
-
-```{warning}
-Before installing the latest version of Parcels, we *highly* recommend creating a new environment so that it doesn't affect your current environment (which you may be using for your research).
-
-You can find your current environment with `conda env list` and identifying the environment with a `*` next to it. At any point, you can use `conda activate ...` (replacing `...` with the name that had the `*` next to it) to return to your environment with version 3 of Parcels.
-```
+**Step 2:** Start a terminal (Linux / macOS) or the Anaconda prompt (Windows). Activate the `base` environment of your Miniconda and create an environment containing Parcels, all its essential dependencies, `trajan` (a trajectory plotting dependency used in the notebooks) and the nice-to-have cartopy and jupyter packages:
 
 ```bash
-conda config --add channels conda-forge
-conda create -n parcelsv4-env python
-conda activate parcelsv4-env
-conda install -c https://prefix.dev/parcels parcels
-conda install trajan cartopy jupyter
-```
-
-<!--
-```{note}
-For some of the examples, `pytest` also needs to be installed. This can be quickly done with `conda install -n parcels pytest` which installs `pytest` directly into the newly created `parcels` environment.
+conda create -n parcels-v4 -c conda-forge parcels trajan cartopy jupyter
 ```
 
 **Step 3:** Activate the newly created Parcels environment:
 
 ```bash
-conda activate parcels
+conda activate parcels-v4
 ```
 
 ```{note}
-The next time you start a terminal and want to work with Parcels, activate the environment with `conda activate parcels`.
+The next time you start a terminal and want to work with Parcels, activate the environment with `conda activate parcels-v4`.
 ```
 
-**Step 4:** Create a Jupyter Notebook or Python script to set up your first Parcels simulation! The [quickstart tutorial](tutorial_quickstart.md) is a great way to get started immediately. You can also first read about the core [Parcels concepts](./explanation_concepts.md) to familiarize yourself with the classes and methods you will use. -->
