+
+This is my over complicated system configuation managed with
+[Puppet](https://puppet.com/), containing all the usual tools you would expect
+from a terminal development workflow.
+
+# Prerequisites
+
+Before you consider using this configuration, it is recommended that you have
+your own repository and you just take what you need from this repository and
+adapt it to your needs. If you really want *this* configuration then it is
+recommended that you fork, review the code and remove anything you don't need.
+
+To install the configuration Puppet Bolt and Git are required to on the system
+so you can run the install scripts.
+
+- [Git](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git)
+- [Puppet Bolt](https://puppet.com/docs/bolt/latest/bolt_installing.html)
+
+# Install 
+
+**NOTE:** Currently the only OS supported is [Ubuntu
+MATE](https://ubuntu-mate.org/), up until 2020 [Ubuntu
+Desktop](https://ubuntu.com/desktop) was used at work so that should have good
+support but really any Debian system should be OK.
+
+```bash
+# Clone the repo
+git clone https://gitlab.com/adeattwood/dotfiles.git ~/.dotfiles
+# Apply the configuration
+site-modules/core/files/bin/dotfiles apply
+```
