-Building and Installing
+Installation
 ----
+The project is header only.  
+Simply point your compiler at the hdr/ directory.  
 
-The usual way works for installing:
+Contributing
+----
+Install cmake and build the project.  
+Dependencies will be installed automatically (using hunter).  
 
 ```bash
-./configure && make && sudo make install
-
+mkdir build
+cd ./build
+cmake ..
+make
 ```
 
-Note, there's nothing to make, so you there's no need to run configure and you can simply point your compiler at the hdr/ directory.
