 ## Usage
 
 To import this package, either download `MPLColorMap.m` and import the file using
-```
+```Mathematica
 << "path/to/MPLColorMap.m";
 ```
 or import the file from this web server using
-```
+```Mathematica
 << "https://git.mieling.net/Thomas/MPL-Colormaps-Mathematica/raw/branch/master/MPLColorMap.m";
 ```
 
 The various color maps are then available as `MPLColorMap["Viridis"]` etc.
 For example:
-```
+```Mathematica
 DensityPlot[Sin[x] Sin[y], {x, 0, 2 \[Pi]}, {y, 0, 2 \[Pi]}, 
- ColorFunction -> MPLColorMap["Viridis"]]
+    ColorFunction -> MPLColorMap["Viridis"]]
 ```
 produces the following image:
