 The YAML maps beambackgroundfiles to different locations and adds some metadata.
 
 ## Installation
-1. Get repo.
+1. Clone the repository.
 2. Set the `BEAMBACKGROUND_JSON` enviroment variable. For ETP this is `/work/jeppelt/etpackground/beambackgrounds.json`
     - If you are not running at ETP, you are responsible to keep the JSON file up to date.

 ### Running in different places
+
 Currently files can be read from these three locations:
  - KEKCC (only if on KEKCC), use `kek` keyword
  - Ceph@ETP (only if on ETP), use `ceph` keyword
  - ETP Belle2 Storage @ GridKA (only if `X509_USER_PROXY` is set), use `gridka` keyword
 
-
 ### Example
-```python
+
+Python:
+```
 beambackgrounds = get_beam_background_by_key("experiment22_run30")
 add_simulation(basf2_path, bkgfiles=beambackgrouns.gridka_file_list)
-
 ```
 
 ### Editing the JSON file
-To update entries in the json file or add new entries, you simply create an `BeambackgroundMetadata` with the desired values. Then call its `update_json_entry` function. Be aware, that this will update the JSON file for everybody, so update with care. If you want to have a special version of a certain entry, create a new entry by setting the `key` property.
