 1. Click **Create project**.
 
+## Push to create a new project
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-ce/issues/26388) in GitLab 10.5.
+
+When you create a new repo locally, instead of going to GitLab to manually
+create a new project and then push the repo, you can directly push it to
+GitLab to create the new project, all without leaving your terminal. If you have access to that
+namespace, we will automatically create a new project under that GitLab namespace with its 
+visibility set to private by default (you can later change it in the UI).
+
+This can be done by using either SSH or HTTP:
+
+```
+## Git push using SSH
+git push git@gitlab.example.com:namespace/nonexistent-project.git
+
+## Git push using HTTP
+git push https://gitlab.example.com/namespace/nonexistent-project.git
+```
+
+Once the push finishes successfully, a remote message will indicate
+the command to set the remote and the URL to the new project:
+
+```
+remote:
+remote: The private project namespace/nonexistent-project was created.
+remote:
+remote: To configure the remote, run:
+remote:   git remote add origin https://gitlab.example.com/namespace/nonexistent-project.git
+remote:
+remote: To view the project, visit:
+remote:   https://gitlab.example.com/namespace/nonexistent-project
