-## Start the Project REPL [↟](#table-of-contents)
+This project is a work in progress -- _very_ early stages!
 
-```shell
-$ rebar3 lfe repl
-```
+If that hasn't scared you off and you would like to play (or even contribute), you can run the latest xrepl code using rebar3_lfe by doing the following:
+
+1. `git clone [email protected]:lfe/xrepl.git`
+1. `cd xrepl`
+1. `mkdir _checkouts && cd _checkouts`
+1. `git clone [email protected]:lfe/rebar3.git`
+1. `cd rebar3 && git checkout release/0.5.x`
+1. `cd ../../../`
+
+At this point, you should be:
+
+1. Back in the xrepl project directory
+1. Have a local copy of the latest rebar3 branch
+1. Be using said branch when you execute `rebar3 lfe ...` commands
