+Conda is required to manage installation of the delivery environment. A fresh installation of {{ conda.installer_name }} is not required for each {{ meta.name }} delivery, however. An existing conda installation may be used. The method described here allows for multiple entirely separate pipeline installations.
+
+A POSIX-compatible shell (e.g. `bash`) is required for all steps below. Python dependencies are taken directly from PyPI or development repositories as needed, so conda's ability to install hybrid conda/pip environments from a YAML specification is used. This requires first downloading the specification file and then creating the environment with it.
+
+------
+
+# Installing Conda
+
+If conda is not available on the target system, it will need to be installed and configured before the delivery environment can be installed.
+
+For detailed instructions of this step, please visit:
+https://conda.io/projects/conda/en/latest/user-guide/install/index.html
+
+**{{ conda.installer_name }}:**
+
+```
+wget {{ conda.installer_baseurl }}/{{ conda.installer_name }}-{{ conda.installer_version }}-{{ conda.installer_platform }}-{{ conda.installer_arch }}.sh
+bash {{ conda.installer_name }}-{{ conda.installer_version }}-{{ conda.installer_platform }}-{{ conda.installer_arch }}.sh
+$HOME/{{ conda.installer_name }}/condabin/conda init
+```
+
+# Installing {{ meta.name }}
+
+## Option 1: Install this delivery
+
+```
+conda env create \
+    --file https://ssb.stsci.edu/stasis/releases/{{ meta.mission }}/{{ info.build_name }}/delivery/{{ info.release_name }}.yml
+```
+
+### Activate this delivery
+
+```
+conda activate {{ info.release_name }}
+```
+
+## Option 2: Install the latest delivery
+
+**Warning:** The `latest` URL may provide software different than what is presented by the release notes section below!
+
+```
+conda env create \
+    --name {{ meta.name }}-latest-py{{ meta.python_compat }} \
+    --file https://ssb.stsci.edu/stasis/releases/{{ meta.mission }}/{{ info.build_name }}/delivery/latest-py{{ meta.python_compact }}-{{ system.platform }}-{{ system.arch }}.yml
+```
+### Activate the latest delivery
+
+```
+conda activate {{ meta.name }}-latest-py{{ meta.python_compat }}
+```
+
+------
+
+Each new delivery iteration will need to be installed using one of the above commands.
