title:Getting the latest version of MAR (code only)
---
If you're already a MAR user, there's a good chance you already have set up a `~/MAR` folder somewhere on a cluster or laboratory machine (e.g., climato\.be for ULiège researchers), where you would find (some of) the content stored in a MAR repository such as [ESPECES/MAR/stable](https://gitlab.uliege.be/especes/mar/stable).
However, for various reasons, there's also a good chance you have already tuned some files present on this repository for your own needs, typically in `~/MAR/bin` and `~/MAR/usr`. Therefore, if you cloned or pulled the entire [ESPECES/MAR/stable repository](https://gitlab.uliege.be/especes/mar/stable) in your ``~/MAR`` folder, you may overwrite some of your own scripts in the process.
You `~/MAR` folder is now linked to a _sparse_ copy from the [ESPECES/MAR/stable](https://gitlab.uliege.be/especes/mar/stable) repository, guaranteeing you can always work with the most up-to-date source code of MAR.
## Updating your repository again
## Updating your copy of the repository again
If you followed all previous steps correctly, the next time you want to update, you will only need to go inside the directory synced with the repository (thus, `~/GitLab/MAR/stable` in this context) and run the final command from the previous section (while in `~/MAR`).
