+## tools
+
+### version control
+
+- git
+
+- github pull request (PR) / gitlab merge request (MR)
+  - merge commit
+  - squash
+  - relation with issue tracker
+- gitflow https://nvie.com/posts/a-successful-git-branching-model/
+  - develop / feature / main / release / hotfixes

+
+### CI tools
+
+- git trigger (webhook)
+- worker
+  - pipeline
+
+#### ci tools type
+##### job base (jenkins)
+- agent (java based) / worker setup
+- Groovy script
+- https://www.jenkins.io/doc/pipeline/examples/
+- plugins
+
+##### code pipeline base (gitlab ci/circle ci)
+- .gitlab-ci.yml
+- rules - Use the rules keyword to specify when to run or skip jobs.
+- cache / artifacts - Keep information across jobs and stages persistent in a pipeline with cache and artifacts. These keywords are ways to store dependencies and job output, even when using ephemeral runners for each job.
