+# fit & finish
+
+* pkgs are installed to `~/.conda/pkgs`
+
+
+# tips
+
+* `conda` requires a shell hook to work, however this doesn’t have to be
+  permanent you can call the following in a terminal instead:
+
+  ```sh
+  source <(conda shell.$(basename $SHELL) hook)
+  ```
+
+  > There is no provided way to unload these hooks
+
+
+# prospects
+
+* conda could be patched to use tea to install python and potentially other
+  such kinds of dependencies
