 2. To create a local repository, clone the remote one via `git clone git@gitea.psi.ch:tschan_d/Master_Thesis.git`. This command creates a new local folder named `repo`, initialises a git repo within it, a remote named `origin` is created, pointing to the connected server, all of the files and and commits are downloaded and the default branch is checked out.
 3. Use `git fetch git@gitea.psi.ch:tschan_d/Master_Thesis.git` to retrieve new work on the remote, without merging everything into the local branches. 
 4. use `git merge REMOTE-NAME/BRANCH-NAME` to merge a remote branch with the local branch.

+6. Local work may be added in a snapshot using either `git add .` to add all files under the current directory to the index, or using specific files `git add file1 file2`. It can be checked what is to be committed using the `git diff --cached`. If `--cached` is omitted, `git diff` will show any changes made but not yet added to the index.
+7. Run `git commit`, which will prompt for a message describing the made changes, and then record a new version of the project.
+8. To combine steps 6 and 7, run `git commit -a` to notice any modified (but not new) files, add them to the index, and commit.
+9. To get an overview over the history, run `git log` or `git log -p`. It may be useful to run `git log --stat --summary`.
