+# Builder Dockerfile
+
+It was annoying to get a consistent environment to build the project in since
+it is currently being developed on Fedora Linux and MacOS and built on Ubuntu.
+
+This should be the source of truth for the build environment and used as a reference for versions etc.
+
+# Usage
+
+## Building it
+
+From this directory:
+
+```shell
+docker build -t sirc:tiledit-builder -f ./builder.Dockerfile .
+```
+
+## Using it
+
+From this directory:
+
+```shell
+podman run --rm -v"$(pwd)/..":/project:z sirc:tiledit-builder meson compile
+podman run --rm -v"$(pwd)/..":/project:z sirc:tiledit-builder meson test
+
+
+```
