     loadEnv(){ . "${HOME}/.nix-profile/dev-envs/${1}"; }
 
-  then nix-env -iA env-nix
-  and
-  $ loadEnv postgresql
+  afterwards execute the new bash shell:
+    $ bash
 
+  the nix expression created is called: env-mytestenv and must appear when searching for it using:
+    $ nix-env -qa '*' | grep nix
+      env-mytestenv
+
+  now we should build our newly defined custom environment using this command on a shell, so type:
+    $ nix-env -iA env-mytestenv
+
+  afterwards load the new environment using:
+    $ loadEnv mytestenv
+  one could also use this function instead:
+    $ load-mytestenv-env
+  the result using either command should be:
+    env-mytestenv loaded
+
+  note: after you typed the above command you will lose all the other tools usually found in a shell you are used to. in this
+        example you will not be able to type 'vi' to edit a file as vi is not included in the dependencies
