-- KIM API 2 package
-
-To install `kimpy`, you need [KIM API](https://openkim.org/kim-api). The
-easiest option for obtaining the KIM API is to install the `kim-api`
-pre-compiled binary package for your preferred operating system or package
-manager. See
-[Obtaining KIM Models](https://openkim.org/doc/usage/obtaining-models) for
-instructions to install the KIM API and the models from OpenKIM on your system.
-
-You can
-[install](https://openkim.org/doc/usage/obtaining-models#installing_api)
-the KIM API from source.
-
-- Python 3.6 or later
-
-You need Python 3.6 or later to run `kimpy`. You can have multiple
-Python versions (2.x and 3.x) installed on the same system without problems.
-
-To install Python 3 for different Linux flavors, macOS and Windows, packages

-### Using pip
-
-**pip** is the most popular tool for installing Python packages, and the one
-included with modern versions of Python.
-
-`kimpy` can be installed with `pip`:
-
-```sh
-pip install kimpy
-```
-
-**Note:**
-
-Depending on your Python installation, you may need to use `pip3` instead of
-`pip`.
-
-```sh
-pip3 install kimpy
-```
-
-Depending on your configuration, you may have to run `pip` like this:
-

-
-### Using pip (GIT Support)
+### Using conda
 
-`pip` currently supports cloning over `git`
+The recommended (and the easiest) way to install `kimpy` is to use the conda package manager to install both the KIM API and kimpy from the conda-forge channel.
 
 ```sh
-pip install git+https://github.com/openkim/kimpy.git
+conda install -c conda-forge kim-api kimpy
 ```
 
-For more information and examples, see the
-[pip install](https://pip.pypa.io/en/stable/reference/pip_install/#id18)
-reference.

-### Using conda
-
-**conda** is the package management tool for Anaconda Python installations.
+### Using pip
 
-Installing `kimpy` from the `conda-forge` channel can be achieved by adding
-`conda-forge` to your channels with:
+This requires that the KIM API alreay be installed on your system. See the KIM-API [docs](https://openkim.org/kim-api/) for instructions on how to do this.
 
 ```sh
-conda config --add channels conda-forge
+pip install kimpy
 ```
 
-Once the `conda-forge` channel has been enabled, `kimpy` can be installed with:
-
-```sh
-conda install kimpy
-```
+### From source
 
-It is possible to list all of the versions of `kimpy` available on your
-platform with:
+This also requires that the KIM API alreay be installed on your system. See above.
