Not clear Documentation or Commands

Hi
I am just getting started with Jakarta EE & Wildfly.

The documentation with Jakarta EE is hard enough, Wildly looks good but its not properly clear.

It is taking me over 3 hours just to add a new user.

I have followed the commands, gone to ./add-user.sh put user name and password,

Now it's asking me to do this:

To represent the user add the following to the server-identities definition

Now, where on earth am I supposed to put this? No information on google, no information on what file?

Is there a tag somewhere? I checked on one article, but no information about the file.

Any advice would be appreciated

Start with the documented ./add-user.sh command and the generated server-identities definition containing the snippet. Identify which configuration file should contain it and update the WildFly documentation with the file location and placement instructions.
