Where is the new Ghost blog theme installed?

Question

CMS

Hello! Either the coffee was not drunk enough, or I'm stupid like that. In general, the essence is in the following:
1) In which directory should I fill in the template? Logically, in the "themes", perhaps?) That's all there is a directory ghost
bower.json
config.example.js
config.js
content core
Gruntfile.js
index.js
LICENSE
my-journey (this is the template I'm trying to install))
node_modules
package .json
PRIVACY.md
README.md I
restart after installation, but the topic does not appear in the blog settings.
