+## Building
+
+docker is used for containerised building.
+
+To build the project, first build the docker image:
+```shell
+docker build -t cryptops-build .
+```
+Then run the container to perform the build process:
+```shell
+docker run --name cryptops-build cryptops-build
+```
+Finally, copy the created binary from the container:
+```shell
+mkdir -p ./bin
+docker cp cryptops-build:/cryptops-api/bin/cryptops-api ./bin/
+```
+
+This binary `cryptops-api`, together with the libraries in `./libraries/`, need to be added to your initrd.
