+# Building
+The only supported build method is using the CMake<br/>
+To build do:
+```
+./packdata.sh
+cmake .
+# or
+# cmake -DCMAKE_BUILD_TYPE=Debug .
+# or
+# cmake -DCMAKE_BUILD_TYPE=Release .
+make
+```
+The result should be in the build-folder. To run
+```
+./saland
+```
+
+## Building using Docker
+
+As getting a C++ project with many dependencies to compile can be a daunting task then I have provided a couple of Docker images that can perform a build. Both for Windows and Linux.
+
+On a fresh checkout you can use:
+```
+docker build . -f extra/docker/Dockerfile -t saland_test
+```
+and
+```
+docker build . -f extra/docker/Dockerfile.WindowsBuild -t saland_test
+```
+
+The Docker files gives a step by step guide to create a build environment.
