+## Third-party packages with rules
+
+If you want to make very specific rules or rules, that you don't want to make public,
+but share with other people.
+You can create a special package with name `thefuck_contrib_*` with following structure:
+
+```
+thefuck_contrib_foo
+  thefuck_contrib_foo
+    rules
+      __init__.py
+      *third-party rules*
+    __init__.py
+    *third-party-utils*
+  setup.py
+```
+
+And thefuck will find all rules from `rules` module.
+
+## Experimental instant mode
+
+By default The Fuck reruns a previous command and that takes time,
+in instant mode The Fuck logs output with [script](https://en.wikipedia.org/wiki/Script_(Unix))
+and just reads the log.
+
+[![gif with instant mode][instant-mode-gif-link]][instant-mode-gif-link]
+
+At the moment only Python 3 with bash or zsh is supported.
+
+For enabling instant mode you need to add `--enable-experimental-instant-mode`
+to alias initialization in your `.bashrc`, `.bash_profile` or `.zshrc` like:
+
+```bash
+eval $(thefuck --alias --enable-experimental-instant-mode)
