+# DS4
+
+An implementation of the Dungeonslayers 4 game system for Foundry Virtual
+Tabletop (http://foundryvtt.com).
+
+## Prerequisites
+
+In order to build this system, a recent version of `npm` is required.
+
+## Building
+
+To build the system, first install all required dependencies:
+
+```
+npm install
+```
+
+Then build the project by running
+
+```
+npm run build
+```
+
+If you'd like the built system to be automatically linked to your local Foundry
+VTT installation's data folder, add a file called `foundryconfig.json` to the
+project root with the following contents befor building:
+
+```
+{
+    "dataPath": "/home/johannesloher/.local/share/FoundryVTT",
+    "repository": "",
+    "rawURL": ""
+}
+```
+
+If you want the system to be continuously build upon every saved change, just
+run
+
+```
+npm run build:watch
+```
