Add docker-build Makefile command.
Add usage instructions for binary and docker to README.
Add ENTRYPOINT to dockerfile to enable handing of additional flags
easier.

+## Local Sequencer
+
+In this repo there is a mock `local-sequencer` server that implements the
+`go-sequencing` interface. This server is useful for testing and development
+purposes.
+
+### Running the local sequencer binary
+
+To run the mock `local-sequencer` server, run the following command:
+
+```sh
+make build
+```
+
+This will build the `local-sequencer` binary. To run the server, run:
+
+```sh
+./build/local-sequencer
+```
+
+You will see an output like the following:
+
+```sh
+2024/11/13 10:56:01 Listening on: localhost:50051
+```
+
+### Running the local sequencer in Docker
+
+To run the mock `local-sequencer` server in Docker, run the following command:
+
+```sh
+make docker-build
+```
+
+This will build a `local-sequencer` Docker image. To run the server, run:
+
+```sh
+docker run -p 50051:50051 --rm local-sequencer
+```
+
+In order to connect your rollup to your local sequencer, you need to pass in the
+rollup ID by using the following command:
+
+```sh
+docker run -p 50051:50051 --rm local-sequencer -listen-all -rollup-id=testing
+```
