 for Vincent Driessen's [branching model](http://nvie.com/archives/323 "original
 blog post").
 
+
+Release 0.1
+-----------
+A quick release of version 0.1 has arrived. The main script are functional and
+should be usable under "normal" use.
+
+There have barely been any real-world tests, but I encourage you to start using
+it actively. [Feedback](http://github.com/nvie/gitflow/issues) is also very
+welcome. See the "Please help out" section below, also.
+
+**Make sure to validate the modifications to your repo after running any of the
+`gitflow` commands, before pushing them permanently.**
+
+
+Installing gitflow
+------------------
+There isn't a real Unix installer available, but the project is so small that
+installing it is easy.
+
+Either:
+
+- Put the `gitflow` directory anywhere on your Unix `PATH` variable; or
+- Run:
+  
+  		$ git clone git://github.com/nvie/gitflow
+  		$ cd gitflow
+  		$ cp gitflow* /usr/local/bin
+
+
 Please help out
 ---------------
-This project is yet unimplemented. And yes, I mean unimplemented. There are no
-scripts yet, but I will use this README file as the "design document" for now,
-so people may start collaborating on it.
+This project is still under development. What is available today is merely its
+foundation. However, it is functional in its current form and should be usable
+under normal use. (Don't try to create multiple release branches next to each
+other and stuff like that, yet.)
+
+Feedback and suggestions are very welcome and I encourage you to use the
+[Issues list](http://github.com/nvie/gitflow/issues) on Github to provide that
+feedback.
 
 Feel free to fork this repo and to commit your additions.
