I am working through getting this example to work.. but not sure how to troubleshoot.

> <https://github.com/openziti/sdk-golang/blob/main/example/simple-server/simple-server.go>

After I compile the application, I run it using the following command

> ./simple-server -c /Users/houst/.zssh/zssh.json -s golanghttp

Is this correct?

> This is the error I receive.

You need to read that code and follow it along. It's not expecting an argument to be passed that indicates the identity nor does it support flags (the `-c` and `-s` you supplied). Not all samples are uniform. This one expects you to set an environment variable named `ZITI_SDK_CONFIG` which represents the path to the json file.

This should work:

```plaintext
export ZITI_SDK_CONFIG=/Users/houst/.zssh/zssh.json
./simple-server golanghttp

```

addendum: ZITI\_SDK\_CONFIG processing will be buried down in the golang-sdk. If the file isn’t supplied to NewContext, the sdk will look for that env variable and use the value as the path to the identity

Awesome… this makes a lot of sense now…
