+# Runner
+Runner is a program to run multiple executables in parallel. I mostly use it to run a server program while also rebuilding a frontend in the background.
+The configuration for it is through a kdl file in the directory it is invoked from. Here's an example config file:
+
+```kdl
+run "frontend" {
+  path "frontend"
+  command "npm"
+  args "run" "dev" 
+}
+
+run "backend" {
+  path "backend"
+  command "cargo"
+  args "run" "--color=always"
+}
+```
+
+This builds a frontend through npm and a cargo server to actually run the backend server. 
+It takes paths to run the commands in as their working directory, arguments are optional if not needed.
