Need assistance in converting Makefile to Shell script - shell

Question

Need your help to convert code in Makefile to Shell script? Please help as I am new to both MakeFile and Shell Scripting.Thanks.
Sample Code:
include Configfile
.PHONY: config-arch asoc-tool clone-repo generate-irx api-login \
upload-file get-app run-scan show-scan-id get-asset-group create-app
config-arch:
sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386
asoc-tool: config-arch
$(eval DIR := $(shell pwd))
curl -o client.zip $(APPSCAN_TOOL)
mkdir client ; mkdir tool
unzip -qq client.zip -d client
cd client ; ls | xargs -I {} sh -c "cp -r {}/* $(DIR)/tool"
rm -rf client
clone-repo:
git clone $(GIT_REPO)
# Generates the irx file for icp-cert-manager.
generate-irx:
$(eval DIR := $(shell pwd))
cd $(PROJECT_NAME); $(DIR)/tool/bin/appscan.sh prepare $(flag)

#!/bin/sh
# config-arch
sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386
# asoc-tool
curl -o client.zip $(APPSCAN_TOOL)
mkdir client ; mkdir tool
unzip -qq client.zip -d client
cd client ; ls | xargs -I {} sh -c "cp -r {}/* ./tool"
rm -rf client
# clone repo
git clone ${GIT_REPO} # you should overwrite ${GIT_REPO} to your git repo, maybe from Configfile
# generate-irx
cd $(PROJECT_NAME)
./tool/bin/appscan.sh prepare ${flag} # you should check your ${flag}, maybe from Configfile
