+Installation
+------------
+For full, detailed instructions, refer to the [documentation for installation](https://mbuild.mosdef.org/en/stable/getting_started/installation/installation_toc.html)
+
+#### `conda` installation quickstart
+`mBuild` is available on `conda` and can be installed as:
+```bash
+conda install -c conda-forge mbuild
+```
+
+#### Installing from source
+
+Dependencies of mBuild are listed in the files ``environment.yml`` (lightweight environment specification containing minimal dependencies) and ``environment-dev.yml`` (comprehensive environment specification including optional and testing packages for developers).
+The ``mbuild`` or ``mbuild-dev`` conda environments can be created with
+
+
+```.. code-block:: bash
+git clone https://github.com/mosdef-hub/mbuild.git
+cd mbuild
+# for mbuild conda environment
+conda env create -f environment.yml
+conda activate mbuild
+
+# for mbuild-dev
+conda env create -f environment-dev.yml
+conda activate mbuild-dev
+
+# install a non-editable version of mbuild
+pip install .
+```
+
+#### Install an editable version from source
+
+Once all dependencies have been installed and the ``conda`` environment has been created, the ``mBuild`` itself can be installed.
+
+``` code-block:: bash
+cd mbuild
+conda activate mbuild-dev # or mbuild depending on your installation
+pip install -e .
+```
