+# Building Zephyr™ Mechanical Keyboard (ZMK) Firmware with Nix
+
+This extension is added by Chris Andreae for MoErgo.
+
+Nix makes setup significantly easier. With this approach West is not needed. You can however still choose to use the ZMK's sanctioned West if you wish.
+
+# To build a target 
+In ZMK root directory,
+
+    nix-build -A *target* [-o *output_directory*]
+	
+An example is 
+    nix-build -A glove80_left -o left
+	
+The output_directory nix creates is a symlink. If you prefer not to rely on symlink (perhaps because you are using WSL on Windows), the following would help
+
+    cp -f $(nix-build -A *target* --no-out-link)/zmk.uf2 .
+
+
+# To build Glove80
+In ZMK root directory,
+    cp -f $(nix-build -A glove80_combined --no-out-link)/glove80.uf2 .
+
+# Adding new targets
+Edit default.nix and add an target based on zmk
+
+An example is:
+
+    glove80_left = zmk.override {
+        board = "glove80_lh";
+     };
