Hi Matt, The build setup of the reference webserver application is the same as the "kernel directory" setup in the documentation. It looks a little different as the reference application is just one component of the entire reference system. If you scroll down a little in the webserver GitHub link, the repo init and repo sync commands pulls the required components of the webserver reference system and organises the components into a directory structure that's similar to the one listed in the "kernel directory" setup in the documentation. The contents of the sel4webserver repository can then be found in the 'projects/webserver' directory after the repo sync command. Regards, Damon
