 ## About [↟](#table-of-contents)
 
-TBD
+This project has a long history of not coming into being, despite there being a need for it in the LFE community from fairly early in the language's history. The [initial impetus](https://github.com/lfe/lfe/issues/153) and all subsquent community feature requests have been 100% inspired by what the larger Clojure community has in the [nREPL](https://nrepl.org/nrepl/1.1/index.html) project.
+
+The xrepl project has as its primary mission:
+
+> To explore strange new LFE REPL use cases, to seek out new REPL features and new interactive development possibilities, to boldly go where LFE-proper hasn't gone. Yet.
+
+Anything good that comes out of this project that may be even remotely useful to LFE itself will result in a ticket and/or a PR against the LFE repository for Robert's reading pleasure and discression.
