+This is based on the work by [samm's repo](https://github.com/samm-git/aws-vpn-client); and you can read their [ blog post](https://smallhacks.wordpress.com/2020/07/08/aws-client-vpn-internals/) for the implementation details.

+This version has taken the shell scripts and folds all of that into a single golang binary.
 
 ## Content of the repository
 
 - [openvpn-v2.4.9-aws.patch](openvpn-v2.4.9-aws.patch) - patch required to build
-AWS compatible OpenVPN v2.4.9, based on the
-[AWS source code](https://amazon-source-code-downloads.s3.amazonaws.com/aws/clientvpn/wpf-v1.2.0/openvpn-2.4.5-aws-1.tar.gz) (thanks to @heprotecbuthealsoattac) for the link.
-- [server.go](server.go) - Go server to listed on http://127.0.0.1:35001 and save
-SAML Post data to the file
-- [aws-connect.sh](aws-connect.sh) - bash wrapper to run OpenVPN. It runs OpenVPN first time to get SAML Redirect and open browser and second time with actual SAML response

+- [main.go](main.go) - a go wrapper to perform the authentication and handle the double-tap of connecting to the vpn
+- [compile-patched-openvpn.sh](compile-patched-openvpn.sh) - bash script to download,patch and compile the openvpn client to use for the golang tool
 
 ## How to use
 
-1. Build patched openvpn version and put it to the folder with a script
-1. Start HTTP server with `go run server.go`
-1. Set VPN_HOST in the [aws-connect.sh](aws-connect.sh)
-1. Replace CA section in the sample [vpn.conf](vpn.conf) with one from your AWS configuration
-1. Finally run `aws-connect.sh` to connect to the AWS.
-
-## Todo
-
-Better integrate SAML HTTP server with a script or rewrite everything on golang
+1. Build patched openvpn version using `compile-patched-openvpn.sh`
+1. Either save your downloaded aws config as `~/.awsvpn.conf` or place it somewhere nice
+1. Compile the go wrapper `go build`
+1. Run the golang tool, use command arg `-config` to point to your conf file if its not saved as `~/.awsvpn.conf`
+1. This should do the rest from here
