-## Step: Install Git LFS
-
-[Git LFS](https://git-lfs.github.com/) (large file storage) is a git extension dealing with large binary files such as images and is used for the documentation. You don't need to worry about anything but you need to install the extension as it is not a part of standard git.

-::: {.win}
-- Git LFS is already part of your regular git installation, to enable it run: `git lfs install` in the command line

-Install via [PackageCloud](https://packagecloud.io/):
-
-```bash
-$ curl -s https://packagecloud.io/install/repositories/github/git-lfs/script.deb.sh | sudo bash
-$ sudo apt-get install git-lfs
-$ git lfs install
-```

-If you do not have rights to install a system package (e.g. on cluster systems) you can [download](https://github.com/git-lfs/git-lfs/releases/latest) a precompiled `git-lfs` executable. Simply put it into your `PATH` and everything should work (remember to run `git lfs install` once!). See also: <https://github.com/git-lfs/git-lfs/wiki/Installation#other>

+Test data is stored in `Tests/Data`. Generated test output files should be found in `[build-dir]/Tests/Data`.
 
 In the OGS-cli outputting to `[build-dir]/Tests/Data` is already handled (via the `-o` parameter). For other executables you have to implement this, e.g. a with parameter specifying the output directory.
 
 In code `BaseLib::BuildInfo::data_path` (from `BuildInfo.h`) references the data source directory and `BaseLib::BuildInfo::data_binary_path` references the data output directory.
 
-For adding new data files make sure you have [setup git lfs](../../getting-started/prerequisites) already. Then simply commit the new files as usual.

-### *The system cannot find the file specified.*
-
-Example error output:
-
-```bash
-open C:\data\code\ogs6\ogs\Tests\Data\Mechanics\Ehlers\ref_axisymmetric_sphere_pcs_0_ts_100_t_1.000000.vtu: The system cannot find the file specified.
-error: failed to push some refs to 'git@github.com:bilke/ogs.git'
-```
-
-Solution:
-
-Fetch all lfs files from `ufz/ogs` and push them to your remote.
-
-```bash
-# this downloads ALL lfs objects from the old lfs server
-git lfs fetch --all origin # or upstream, this should point to ufz/ogs
-
-# pushes ALL lfs objects to the new lfs server
-git lfs push --all my-remote # this should point to your remote
