+later, which is installed basically everywhere (and in any context involving
+remote jobs, like hadoop, SSH, docker, etc, ni automatically installs itself so

 ## For ni developers
+### [Amazingly cool development documentation](dev/README.md)
+
+### How to test your changes
+```sh
+$ ./test                        # accurate but time-consuming; see below
+```
+
+`./test` automatically rebuilds your `./ni` image from source.
+
+If you've just made a small change and don't want to wait the full ten minutes
+it takes to run all tests on all distributions, here's a lighter-weight way to
+do it:
+
+```sh
+$ ./test --build                # if you're testing for the first time
+$ ./test --quick centos-5       # faster than running all tests
+$ ./test --quick ubuntu-16.04   # includes hadoop/spark/docker tests
+```
+
+### Main files and what they do
 - `./boot`: create the base `ni` image with no extensions. This image does
   almost nothing and is effectively unusable.
 - `bugs/`: documentation and tests for all nontrivial bugs I've found, starting
