+## Installation
+
+`go get -u github.com/jjdekker/chronozinc`
+
+## Sample Configuration
+
+The following configuration can be used to time a model using `flatzinc`,
+`fzn-gcode` and `fzn-or-tools`. Running is as easy as: `chronozinc config.toml
+model.mzn data1.dzn data2.dzn`.
+
+Tip: Remove the parameters line and place it in
+`$HOME/.config/chronozinc/settings.toml` or `/etc/chronozinc/settings.toml`. You
+can now make project specific settings files while using the solvers settings as
+declared in this file.

 ## TODO
 - Remove all usage of `viper` from parsing and runtime packages
 - Provide separate the `run` and `parse` commands
+- Internal data transformation
 - MORE DOCUMENTATION!!!
