+# land
+
+A simple little "land" to run webassembly programs in.
+
+## Building
+
+First, install [tup](http://gittup.org/tup/index.html).
+
+### I have FUSE
+
+```console
+$ tup init
+$ tup
+```
+
+### I don't have FUSE
+
+```console
+$ tup init
+$ tup generate build.sh
+$ ./build.sh
+```
+
+## Usage
+
+Not very usable outside of the tests in `cmd/land` yet :(. All webassembly modules require an exported function main that returns an i32. TODO: argv.
