 creating a `DrawerOperation` and not using it, also call `validate` and print out the error if there is one. This means
 we also need to `impl Display` on `DrawerError`.
 
+### Phase 3
+
+For phase 3 we want to start implementing the `close` command. We'll get the tar part working but not worry about encryption yet.
+
+- Make a new method `perform` on `DrawerOperation` which takes `&self` and returns `Result<(), DrawerError>`.
+- `perform` should first call `validate` and return the error if there is one.
+- After that, it should call either `open(&self)` or `close(&self)` depending on the operation type. For now, `open` will just be a `todo!()`
+- The new `close` method should create a vec<u8> consisting of the contents of the target directory as a tarball (use the tar create we depend on)
+- After creating the vec, it should write it out to the drawer file path.
+
+I'm going to add some test data to the project under `tests/` but it's just random data to test, ignore the contents of all those files.
+
+### Phase 3a
+
+As a minor improvement, make the `perform_close` method also gzip the contents of the tarball.
