-If you want to live dangerously, you can install the still-in-progress pandoc (and pandoc-citeproc) from github.  You'll need git and [stack](https://github.com/commercialhaskell/stack/releases).  Grab the stack binary that is appropriate for your platform and put it somewhere in your path.
+If you want to live dangerously, you can try the unofficial [pandoc-nightly builds](https://github.com/pandoc-extras/pandoc-nightly), or install the still-in-progress pandoc from GitHub.  You'll need git and [stack](https://github.com/commercialhaskell/stack/releases).  Grab the stack binary that is appropriate for your platform and put it somewhere in your path.
 
 Then:
 
-    mkdir pandoc-build
-    cd pandoc-build
-    git clone https://github.com/jgm/pandoc-types
-    git clone https://github.com/jgm/texmath
-    git clone https://github.com/jgm/pandoc-citeproc
     git clone https://github.com/jgm/pandoc
-    git clone https://github.com/jgm/cmark-hs
-    git clone https://github.com/jgm/zip-archive
     cd pandoc
-    git submodule update --init
-    stack install --test --install-ghc --stack-yaml stack.full.yaml
+    stack setup # only first time
+    stack install
 
-The `stack install` command will let you know where it put the binaries (pandoc and pandoc-citeproc).  You may have to add this location (`~/.local/bin`, on linux and OSX systems) to your path.
+Depending on your needs, you'll have to do the same for the following repositories:
+
+    https://github.com/jgm/pandoc-types
+    https://github.com/jgm/texmath
+    https://github.com/jgm/pandoc-citeproc
+    https://github.com/jgm/cmark-hs
+    https://github.com/jgm/zip-archive
 
-To pull in the latest changes, after you've done this and there have been changes in the repositories:  Visit each repository in pandoc-build (pandoc-types, texmath, pandoc-citeproc, pandoc, zip-archive, cmark-hs) and do `git pull`.  In the pandoc repo, also do `git submodule update` and `stack install --test --stack-yaml stack.full.yaml`.
