 Replacing `v0.x.x` with the current version that's listed. Note this may take several minutes. Once the process is complete, the user can copy them to the Minikube cache.

+# Managing Conda Environments
+
+QHub has several ways to manage environments for users. The
+traditional approach available in older QHub deployments is still
+available by editing the `qhub-config.yaml` `environments:` key within
+the configuration file. An example would be 
+
+```yaml
+environments:
+  "environment-default.yaml":
+    name: default
+    channels:
+      - conda-forge
+      - defaults
+    dependencies:
+      - python=3.7
+      - ipykernel
+      - ipywidgets
+      - qhub-dask==||QHUB_VERSION||
+      - numpy
+      - numba
+      - pandas
+```
+
+When the environments are updated in this file and an automated `qhub
+deploy` is kicked off the environments are updated for all users. An
+additional method is allowed which enables users to easily create
+ad-hoc environments. Visiting `https://<qhub-domain>/conda-store/`
+will take you to
+[Conda-Store](https://conda-store.readthedocs.io/en/latest/) an open
+source tool for managing conda environments within enterprise
+environments. For now the username is anything with a password of
+`password`. Soon this will be integrated with central authentication
+via keycloak. The [create environment
+endpoint](https://conda-store.readthedocs.io/en/latest/user_guide.html#create-create-environment)
+will allow you to easily create a new environment. Additionally you
+can update existing environments via [visiting the
+environment](https://conda-store.readthedocs.io/en/latest/user_guide.html#environment-namespace-name-environments)
+and clicking edit. 
+
+We are working towards developing an extension within jupyterlab for
+editing these environments but it is not complete at the
+moment. Follow [gator](https://github.com/mamba-org/gator) for
+progress on this extension.
