-#+TITLE: README for Guile-Nrepl
+#+TITLE: README for Guile-nREPL
 
+* Description
+nREPL server implementation for guile.
+
+* Spells for working with the project
+
+If you have guix and org-mode, the src blocks in this section can be executed directly from this doc.
+
+** Building
+To build the project, you need hall, autoconf, guile, and automake. If you are running guix, you just need to run a =guix shell= to get all the requirements.
+
+#+begin_src shell
+  guix shell -m manifest.scm -f guix.scm # Skip if you do not use guix
+  hall build -x
+  autoreconf -vif
+  ./configure
+  make
+#+end_src
+
+** Testing
+After the project is built, test the project via:
+
+#+BEGIN_SRC shell
+  make check
+#+END_SRC
+
+** Cleaning
+To get back to a clean state, run:
+
+#+BEGIN_SRC shell
+  hall clean -x
+#+END_SRC
+
+** Misc Incantations
+Other things that may be useful.
+*** Load shell in direnv
+If you use direnv, you can drop into the shell automatically with:
+
+#+BEGIN_SRC shell
+  echo 'eval $(guix shell --search-paths -m manifest.scm -f guix.scm)' > .envrc
+  direnv allow
+#+END_SRC
