+# vis-build - asynchronously run (build) commands
+
+This is a simple `vis` plugin to asynchronously run any shell command using
+the `vis:communicate` API.
+
+I use the plugin to run build commands while keeping my editor usable.
+
+## Configuration
+
+By default, the `build` will execute `make(1)` in the current directory.
+The used build command can either be passed as first argument to `build` or
+is retrieved by calling the function `build.get_default_build_cmd`.
+
+So in order to change the default build command to ninja add this snippet to
+you `visrc.lua`:
+
+```lua
+local build = require('plugins/vis-build')
+build.get_default_build_cmd = function() return 'ninja' end
+```
+
+## Bindings
+
+`<M-b>` is bound to the `build` command.
