+# Environment variables
+
+Run the script `/bin/set_environment.sh` or put the following in your `~/.bashrc`
+
+```bash
+RESEARCH_ROOT=/path/to/your/local/clone ; export RESEARCH_ROOT
+```
+or navigate to `/your/local/clone` and just type
+```bash
+RESEARCH_ROOT=`pwd` ; export RESEARCH_ROOT
+```
+All scripts and commands will assume, that the variables have been properly set. In GitLab CI, this is done as the `default` `before_script`:
+```yaml
+default:
+  before_script:
+    - RESEARCH_ROOT=`pwd`; export RESEARCH_ROOT;
+```

 # Docker
 
 During [CI/CD]() various [docker](https://www.docker.com/) images are used. All images that are used by the pipeline, are also stored in the [container registry](https://docs.gitlab.com/ee/user/packages/container_registry/) of this repository. In case of changes in `/docker` the pipeline is configured to update these images as well (check out the `Docker-update` in the [stages section of the wiki](Continuous-Integration-and-Continuous-Deployment#pipeline)).
