+# webpull
+
+Webpull allows you to update your live website without deploying a new docker container but by simply calling an URL
+
+You need to specify a secret token at boot:
+
+```
+WEBPULL_TOKEN=s3cr3et ./webpull
+```
+
+## Node.js version
+
+```
+go build ./main.go
+sudo docker build -f ./Dockerfile.nodejs -t superboum/amd64_webpull_pug:v1 .
+```
+
+## Ruby version
+
+```
+go build ./main.go
+sudo docker build -f ./Dockerfile.ruby -t superboum/amd64_webpull_ruby:v1 .
+```
