+# Async Network Engine
+
+Unity http requests made easy to interoperability with Go Lang + Google Protobuf functions!
+
+Supported Cloud Functions:
+- Google Cloud Functions
+- Amazon Web Services Lambdas
+
+Use at your own risk!
+
+# How to install
+
+At package.json, add these 3 lines of code:
+```json
+"com.gameworkstore.asyncnetworkengine": "git://github.com/GameWorkstore/async-network-engine.git",
+"com.gameworkstore.googleprotobufunity": "git://github.com/GameWorkstore/google-protobuf-unity.git",
+"com.gameworkstore.patterns": "git://github.com/GameWorkstore/patterns.git"
+```
+
+And wait for unity to download and compile the package.
+
+for update package for a newer version, install UpmGitExtension and update on [ Window > Package Manager ]!
+> https://github.com/mob-sakai/UpmGitExtension
+
+# Usage Examples
+
+You can find usage examples on Assets/Tests/ folder, for each cloud.
+
+## Uploading to Google Cloud Functions
+
+on upmsync, the job 'upload_gcp' illustrates a possible way to upload your functions into GCP.
+Requires a service account to enable it to upload.
+
+## Uploading to Amazon Web Services
+
+on upmsync.yaml, the job 'upload_aws' illustrates a possible way to upload your functions into AWS.
+Requires a service account to enable it to upload.
+> You need to set the template 'cloudformation_function.yaml' public in your bucket repository to enable AWS::Stack to read from it.
+
+# Implementation
+
+## GCP Troubleshoot
+
+> My function is returning ErrorProtocol for any input.
+if you don't give access public for your function it might fail
+
+## AWS Troubleshoot
+> CloudFormation is returning errors
+
+Verify all variables, !Ref and links, you might be forgetting something. CloudFormations is very sensitive to linkage errors.
+
+> My lambda is returning error 500 Internal Server error.
+If you are receiving this and error object is returning null, it might be a bad configuration causing your lambda to not run.
+Verify if you function is running by adding a fmt.Println("test") at main() function to ensure the function is starting.
+Some issues that may prevent the start of function:
+- The functions ins't at correct path when extracted from the zip.
+- The function package name isn't main where main() function is declared.
+- lambda.Start() is never begin called to initialize the function.
+- The function is crashing upon initialization
+
+If the function is working normally, them you might receive error 500 - ErrorInternalServer with AWSError, when specified by the programmer.
+
+# Contributions
+
+If you are using this library and want to submit a change, go ahead! Overall, this project accepts contributions if:
+- Is a bug fix;
+- Or, is a generalization of a well-known issue;
+- Or is performance improvement;
+- Or is an improvement to already supported feature.
+
+Also, you can donate to allow us to drink coffee while we improve it for you!
