 > Run a full Bitcoin node with one command
 
 A Docker configuration with sane defaults for running a full Bitcoin node.
 
 ## Usage
 
 ```
-docker run --name bitcoind -v $HOME/.bitcoin:/data/.bitcoin -p 8333:8333 lukechilds/bitcoind
+docker run --name bitcoind -v $HOME/.bitcoin:/data/.bitcoin -p 8333:8333 getumbrel/bitcoind:<version-tag>
+```
+
+Replace the tag `<version-tag>` with the available version that you want to run. For example, to run version 27.1, use the tag `v27.1`:
+
+```
+docker run --name bitcoind -v $HOME/.bitcoin:/data/.bitcoin -p 8333:8333 getumbrel/bitcoind:v27.1
 ```

-### Version
+### Versions
 
-Run a specific version of bitcoind if you want.
+Images for versions starting from v27.1 are available. To run a specific available version, use the appropriate tag.
 
 ```
-docker run --name bitcoind -v $HOME/.bitcoin:/data/.bitcoin -p 8333:8333 lukechilds/bitcoind:v0.18.1
+docker run --name bitcoind -v $HOME/.bitcoin:/data/.bitcoin -p 8333:8333 getumbrel/bitcoind:v27.1
 ```
 
 ## Build
 
-Build this image yourself by checking out this repo, `cd` ing into it and running:
+A multi-architecture (amd64 and arm64) image is automatically built and published to Docker Hub when new tags are pushed in the format `v*.*.*` (e.g., `v25.0.0`).
 
-```
-docker build -t lukechilds/bitcoind .
-```
-
-You can build a specific version by passing in the `VERSION` build arg:
+If you want to build this image yourself, check out this repo, `cd` into it, and run:
 
 ```
-docker build --build-arg VERSION=0.18.1 -t lukechilds/bitcoind:v0.18.1 .
+docker buildx build --platform linux/amd64,linux/arm64 --build-arg VERSION=<version> -t <image_name>:<tag> --push .
 ```
 
-You can build a specific architecture by passing in the `ARCH` build arg:
-
-```
-docker build --build-arg ARCH=amd64 -t lukechilds/bitcoind:amd64 .
-```
+Replace `<version>` with the Bitcoin Core version you're building (without the 'v' prefix), and `<image_name>:<tag>` with your desired image name and tag.
 
-For a full list of supported build arg options, check out the [build script matrix](https://github.com/lukechilds/docker-bitcoind/blob/master/.github/workflows/build.yml).
+The Dockerfile supports `linux/amd64` and `linux/arm64` architectures only.
