+## Docker
+
+### Build instructions
+
+First, build a base image
+
+```
+docker build . -t ghcr.io/jrodal98/nvim:<version>
+```
+
+Next, run a container
+
+```
+docker run -it --rm --name nvim_docker_base ghcr.io/jrodal98/nvim:<version>
+```
+
+Finally, we must manually complete the build, due to issues with running packer headless.
+
+1. Run `nvim`, which will trigger the initial packersync (you may see errors - this is okay)
+2. Close nvim and then run `nvim` again
+3. Wait for all the treesitter and mason LSP configs to download
+4. Outside of the container, open another terminal and run this to save the image: `docker container commit --change='ENTRYPOINT ["/usr/bin/nvim"]' nvim_docker_base ghcr.io/jrodal98/nvim:<version>`
+
+To upload it to ghcr without a github action...
+
+1. `docker login ghcr.io`
+2. enter github username and access token
+4. `docker tag ghcr.io/jrodal98/nvim:<version> ghcr.io/jrodal98/nvim:latest`
+5. `docker push ghcr.io/jrodal98/nvim:latest`
+
