+# BOINC Blender application for BOINC Central
+
+An application to run Blender rendering tasks on [BOINC Central](https://boinc.berkeley.edu/central/).
+
+## Command Line Usage
+
+```
+./boincblender \
+  -blender /bin/blender \
+  -workdir /app \
+  -input scene.blend \
+  -output renders/frame_#### \
+  -frame 1 \
+  -engine CYCLES \
+  -cyclesDevice CPU \
+  -imageFormat PNG \
+  -threads 4
+```
+
+Key flags:
+- `-blender` Path to Blender executable (default `/bin/blender` inside the container)
+- `-workdir` Working directory (where input/output live)
+- `-input` (required) `.blend` file name relative to workdir
+- `-output` Output prefix (Blender will add frame numbering)
+- `-frame` Frame number to render
+- `-engine` `CYCLES` or `EEVEE`
+- `-cyclesDevice` Device when using Cycles: `CPU|CUDA|OPTIX|HIP|ONEAPI|METAL`
+- `-imageFormat` One of `TGA, RAWTGA, JPEG, IRIS, AVIRAW, AVIJPEG, PNG, BMP, HDR, TIFF`
+- `-threads` Thread count passed to Blender `-t`
+
+A `fraction_done` file (0.000–1.000) is updated as progress lines are parsed and written from Blender output.
+
+## Building Locally
+
+Requires Go 1.22+.
+
+```
+go build ./boincblender.go
+```
+
+## Docker / Container Usage
+
+The provided `Dockerfile` downloads Blender and sets up a minimal runtime.
+
+Build the image:
+```
+docker build -t boinc-blender:latest .
+```
+
+Run (expecting an `input.zip` containing the `.blend` and any assets):
+```
+docker run --rm -v "$PWD":/app -e ARGS="-input scene.blend -output frame_#### -frame 1 -engine CYCLES -threads 4" boinc-blender:latest
+```
+
+The next parameters are mandatory:
+- `-input` (required) `.blend` file name relative to `/app`
+- `-output` Output prefix (Blender will add frame numbering)
+- `-frame` Frame number to render
