+#
+# First-time setup: this nixpkg downloads the conda installer and provides a FHS
+# env in which it can run. On first use, the user will need to install conda to
+# the installPath using the installer:
+# $ nix-env -iA conda
+# $ conda-shell
+# $ conda-install
+#
+# Under normal usage, simply call `conda-shell` to activate the FHS env,
+# and then use conda commands as normal:
+# $ conda-shell
+# $ conda install spyder
