+# Median Cut
+
+To compile and run, one has to first download
+[stack](https://docs.haskellstack.org/en/stable/README/)
+
+The simplest way to do this is by executing the following command:
+
+```
+curl -sSL https://get.haskellstack.org/ | sh
+```
+
+Then run setup in this directory:
+
+```
+stack setup
+```
+
+Finally the executable can be built and run using the following:
+
+```
+stack build --exec mirror-ball
+```
+
+This project relies on a open source library that I wrote to load 
+PFM files which is hosted at [PFM](https://github.com/ymherklotz/pfm).
+It will automatically get downloaded when built with stack.
