+# Ollama with a preloaded model
+
+An [`ollama/ollama:latest`](https://hub.docker.com/r/ollama/ollama) image with the following model downloaded during the build:
+
+```text
+orcarouter/Qwen3.8-27B-Uncensored:q3_K_L
+```
+
+The image is published to the public Gitea container registry as:
+
+```text
+gt.uo1.net/1movmedia/ollama-with-model:latest
+```
+
+## Run
+
+```sh
+docker pull gt.uo1.net/1movmedia/ollama-with-model:latest
+docker run --rm --gpus all -p 11434:11434 \
+  gt.uo1.net/1movmedia/ollama-with-model:latest
+```
+
+The Ollama API is then available at `http://localhost:11434`. Start a request with the preloaded model:
+
+```sh
+curl http://localhost:11434/api/generate \
+  -d '{"model":"orcarouter/Qwen3.8-27B-Uncensored:q3_K_L","prompt":"Hello"}'
+```
+
+Remove `--gpus all` to run without an NVIDIA GPU.
+
+## Build locally
+
+The base image and model have defaults and can be overridden with Docker build arguments:
+
+```sh
+docker build -t ollama-with-model:latest .
+
+docker build -t ollama-with-model:custom \
+  --build-arg BASE_IMAGE=ollama/ollama:latest \
+  --build-arg MODEL=orcarouter/Qwen3.8-27B-Uncensored:q3_K_L \
+  .
+```
+
+Building downloads the complete model, so the runner needs enough disk space for the Ollama base image, model data, and build layers.
+
+## Publish from Gitea Actions
+
+The workflow in `.gitea/workflows/publish.yml` builds and publishes the `latest` tag on pushes to `main`. It can also be started manually with `workflow_dispatch`.
+
+Configure the following repository Actions variable and secret before running it:
+
+- Variable `REGISTRY_USERNAME`: a Gitea user with write access to the `1movmedia` package registry.
+- Secret `REGISTRY_TOKEN`: a Gitea personal access token with package read/write permission.
+
+The `1movmedia` organization must be public for unauthenticated image pulls.
