+First, fork and clone this practice repository.
+
+Add a remote to the upstream repository:
+```bash
+$ cd advanced-practice
+$ git remote add upstream ssh://git@git-r3lab-server.uni.lu:8022/R3/school/git/advanced-practice.git
+$ git fetch
+```
+
+Then, create a separate branch from the develop branch:
+```bash
+$ git checkout -b myBranch upstream/develop
+```
+
+Add your name file in the `attendees` directory:
+
+When you are done editing your file, add the file to the stage and commit it:
+```bash
+$ git add attendees/myName.md
+$ git commit -m "Edit the content of the subpage myName.md"
+```
+
+Once you are done committing, you can push your branch to your fork:
