+## bitcoin server
+
+A linux image can be generated with the script below. Currently, this is only tested against the `version3` branch with or without the `v3.8.0` tag.
+
+### linux
+
+The following outlines usage of the `bs-linux` artifacts.
+It is of note that the generated image includes a `startup.sh` script which conditionally initializes the blockchain database if not found.
+
+#### Initialization
+
+The following populates a provided image build directory:
+
+```
+./bs-linux.sh --build-dir=<image build dir> --source=<gsl xml source> --init-only
+```
+
+The reader then needs to edit the generated `bs-linux.env` to provide storage paths for volume mounting.
+Additionally, the `STORAGE_BITCOIN_CONF` path should contain a `bs.cfg` containing a `directory` field for `[database]` which has some depth from the volume mount point, due to `bs` implementation attempts to create the blockchain containing directory.
+
+#### Image construction
+
+The image construction can then continue via an other invocatio with the following parameters:
+
+```
+./bs-linux.sh --build-dir=<image build dir> --source=<gsl xml source> --build-only
+```
+
+#### Container management
+
+The file `bs-linux.yml` is provided in the image build directory in order to allow `docker compose` to control container construction and destruction.
+The reader is free to translate this file and the `bs-linux.env` into `docker` commands derived from the declative `yaml`.
+The timeout parameter should be noted: `bs` has been known to take an extended period of time to write memory to disk and `SIGKILL` will likely corrupt the database.
+
+##### Instantiating container
+```
+docker compose --env-file bs-linux.env --file bs-linux.yml up -t 3600 -d
+```
+
+##### Terminating container
+```
+docker compose --env-file bs-linux.env --file bs-linux.yml down -t 3600 -v
+```
