feat: added vlang dockerfile

README.md

 Vieter requires several tools to be developed, one of which being a specific
 version of Vlang. This repository manages Dockerfiles & other packages for
 these various tools.
+
+## Build instructions
+
+Most stuff in this repository is built automatically using my CI. These
+instructions can be found in [`.woodpecker`](./.woodpecker).
+
+### Vlang Docker image
+
+The Vlang Docker image takes too long to build on my CI, mostly because it
+needs to be built for both arm64 & aarch64. It can be built by running the
+following command in the `vlang` directory:
+
+```sh
+docker buildx build \
+    --platform linux/amd64,linux/arm64 \
+    -t 'git.rustybever.be/chewing_bever/vlang:d1f57ead713c8e5254d8cef22991e6409dc1f06b-alpine3.17' \
+    -t 'git.rustybever.be/chewing_bever/vlang:latest' \
+    --push .
+```
+
+The hash in the tag corresponds to the tag of the vlang repository.
