 Execute docker build and push using docker caches.
 
+## Github Action

+```yml
+  - uses: devmasx/[email protected]
+    with:
+      image_name: devmasx/project-name
+      cache_stage_target: builder
+      build_params: --build-arg=NPM_TOKEN=${{secrets.NPM_TOKEN}}
+``
 ## Docker build
 
 Use the latest docker image for use as cache
 Docker commands example:
 
 ```
+
 npx cached-docker-build-push --image-name image-name --image-tag v1
+
 ```
 
 Execute this docker commands:
 
 ```
+
 docker pull image-name || exit 0
 docker build --cache-from=image-name -t image-name -t image-name:v1
 docker push image-name:v1
 docker push image-name
+
 ```
 
 ## Docker build with multi stage
 
 With multi stage we need to save the builder stage for use as cache. Use the flag `--cache-stage-target` for define the builder stage
 
 ```
+
 npx cached-docker-build-push --cache-stage-target=builder --image-name image-name --image-tag v1
+
 ```
 
 Execute this docker commands:
 
 ```
+
 docker pull image-name:cache-builder
 docker build \
-  --cache-from=image-name:cache-builder \
-  --target builder \
-  -t image-name:cache-builder \
-  .
+ --cache-from=image-name:cache-builder \
+ --target builder \
+ -t image-name:cache-builder \
+ .
 
 docker build \
-  --cache-from=image-name:cache-builder \
-  -t image-name \
-  -t image-name:v1 \
-  .
+ --cache-from=image-name:cache-builder \
+ -t image-name \
+ -t image-name:v1 \
+ .
 
 docker push image-name:cache-builder
 docker push image-name:v1
 docker push image-name
+
+```
+
 ```
