-# Contour creation with marching squares
-This program takes a tiff heightmap and produces vector contours 
+# Contour Creator 🗺️
+This program takes a tiff heightmap and produces vector contours.
+This is our project for the INF205: Resource-efficient programming course
+## Status
+- [x] Read .tif file into memory using gdal
+- [ ] Run the marching squares algorithm and produce a "casemap"
+- [ ] Use a lookuptable to produce a vector file from the "casemap"
+
+## How to build:
+```
+mkdir build
+cd build
+cmake -DCMAKE_BUILD_TYPE=Debug ..
+cmake --build . --parallel
+```
+Then you can run `./contour-creator`
