+# Custom builds  of components
+
+
+The following guide will provide information on how to build images of the sub systems such as consensus/network node, mirror node importer/rest/grpc and relay.
+
+### Prerequisite
+
+- [Node.js](https://nodejs.org/) `>= v18.x`
+  - Node version check: `node -v`
+- NPM `>= v10.5.0`
+  - NPM version check: `npm -v`
+- [Docker](https://www.docker.com/) `>= v20.10.x`
+  - Docker version check: `docker -v`
+- [Docker Compose](https://docs.docker.com/compose/) `=> v2.12.2`
+  - Docker Compose version check: `docker compose version`
+- Minimum 16GB RAM
+
+
+## The Hedera Local Node
+To setup Hedera Local Node project using custom images, please first clone the repo:
+
+```
+git clone https://github.com/hashgraph/hedera-local-node.git
+```
+
+In the following guide we have chosen to use tag `local` for the locally created images. This value should be set in `value` key in `./src/configuration/local.json` for the corresponding image. The example below will set all images to be the one that are locally built:
+
+```
+{"key": "NETWORK_NODE_IMAGE_TAG", "value": "local"},
+{"key": "HAVEGED_IMAGE_TAG", "value": "local"},
+{"key": "MIRROR_IMAGE_TAG", "value": "local"},
+{"key": "RELAY_IMAGE_TAG", "value": "local"},
+{"key": "MIRROR_NODE_EXPLORER_IMAGE_TAG", "value": "local"}
+```
+
+Please review the steps below on how to build each image. When they are created and `local.json` is populated accordingly, you can proceed with running The Hedera Local Node as usual.
+
+## Building Custom images
+### Build Consensus/Network node image
+
+  - For building consensus/network image clone `hedera-services` repo:
+    ```
+    git clone https://github.com/hashgraph/hedera-services.git
+    ```
+
+ - Change current directory to `hedera-services` repo:
+    ```
+    cd hedera-services
+    ```
+
+- Please run the following commands:
+  ```
+  ./gradlew clean
+  ./gradlew assemble
+  ```
+
+ - Create directory `docker/main-network-node/sdk`:
+    ```
+    mkdir -p ./hedera-node/infrastructure/docker/containers/local-node/main-network-node/sdk
+    ```
+
+ - Copy needed artifacts:
+    ```
+    cp -r ./hedera-node/data ./hedera-node/infrastructure/docker/containers/local-node/main-network-node/sdk
+    ```
+
+ - Build `network-node-base` image:
+    ```
+    BUILD_PATH="./hedera-node/infrastructure/docker/containers/local-node/network-node-base/"
+
+    docker build -t gcr.io/hedera-registry/network-node-base:local \
+      -f $BUILD_PATH/Dockerfile \
+      $BUILD_PATH
+    ```
+
+ - Build `main-network-node` image:
+    ```
+    BUILD_PATH="./hedera-node/infrastructure/docker/containers/local-node/main-network-node/"
+
+    docker build --build-arg IMAGE_TAG=local \
+      -t gcr.io/hedera-registry/main-network-node:local \
+      -f $BUILD_PATH/Dockerfile \
+      $BUILD_PATH
+    ```
+
+## Build Haveged image
+  - For building haveged image clone `hedera-services` repo:
+
+    ```
+    git clone https://github.com/hashgraph/hedera-services.git
+    ```
+
+ - Change current directory to `hedera-services` repo:
+
+    ```
+    cd hedera-services
+    ```
+  
+  - Build `network-node-haveged` image:
+
+    ```
+    BUILD_PATH="./hedera-node/infrastructure/docker/containers/local-node/network-node-haveged/"
+
+    docker build \
+      -t gcr.io/hedera-registry/network-node-haveged:local \
+      -f $BUILD_PATH/Dockerfile \
+      $BUILD_PATH
+    ```
+
+## Build Mirror node images
+  - For building mirror images clone `hedera-mirror-node` repo:
+    
+    ```
+    git clone https://github.com/hashgraph/hedera-mirror-node.git
+    ```
+
+  - Change current directory to `hedera-mirror-node` repo:
+    
+    ```
+    cd hedera-mirror-node
+    ```
+
+  - Please run the following commands:
+    
+    ```
+    ./gradlew clean
+    ./gradlew assemble
+    ```
+
+  - Build `hedera-mirror-monitor`, `hedera-mirror-grpc`,`hedera-mirror-web3`,`hedera-mirror-rest`,`hedera-mirror-importer` images:
+
+    ```
+  
+    docker build -t gcr.io/mirrornode/hedera-mirror-monitor:local -f ./hedera-mirror-monitor/Dockerfile ./hedera-mirror-monitor
+
+    docker build -t gcr.io/mirrornode/hedera-mirror-grpc:local -f ./hedera-mirror-grpc/Dockerfile ./hedera-mirror-grpc
+
+    docker build -t gcr.io/mirrornode/hedera-mirror-web3:local -f ./hedera-mirror-web3/Dockerfile ./hedera-mirror-web3
+
+    docker build -t gcr.io/mirrornode/hedera-mirror-rest:local -f ./hedera-mirror-rest/Dockerfile ./hedera-mirror-rest
+
+    docker build -t gcr.io/mirrornode/hedera-mirror-importer:local -f ./hedera-mirror-importer/Dockerfile ./hedera-mirror-importer
+    ```
+
+## Build Relay node image
+  - For building relay image clone `hedera-json-rpc-relay` repo:
+
+    ```
+    git clone https://github.com/hashgraph/hedera-json-rpc-relay.git
+    ```
+
+  - Change current directory to `hedera-json-rpc-relay` repo:
+
+    ```
+    cd hedera-json-rpc-relay
+    ```
+
+  - Build `hedera-json-rpc-relay` images:
+
+    ```
+    docker build -t ghcr.io/hashgraph/hedera-json-rpc-relay:local -f Dockerfile .
+    ```
+
+## Build Mirror node Explorer image
+  - For building explorer image clone `hedera-mirror-node-explorer` repo:
+
+    ```
+    git clone https://github.com/hashgraph/hedera-mirror-node-explorer.git
+    ```
+
+  - Change current directory to `hedera-mirror-node-explorer` repo:
+
+    ```
+    cd hedera-mirror-node-explorer
+    ```
+
+  - Change current directory to `hedera-mirror-node-explorer` repo:
+
+    ```
+    cd hedera-mirror-node-explorer
+    ```
+
+  - Build `hedera-mirror-node-explorer` images:
+
+    ```
+    npm i 
+    npm run build
+    docker build -t gcr.io/hedera-registry/hedera-mirror-node-explorer:local .
+    ```
