+# CereSaves
+~~(aka Syncthing-CloudSaves)~~
+
+This is a basic little wrapper utility that automatically checks to see if newer savedata exists in some sort of synced directory, and automatically loads in any newer data it finds.
+
+Obviously this is a WIP and not very good, but I wanted a quick and dirty cloud saves solution for non-steam games.
+
+## Installation
+```bash
+git clone repo_url_here.git
+cd reponame
+```
+Edit `stcs-global-config.sh`
+* `STCS_SAVEGAME_SYNCDIR` should point to the folder being synced by your syncing solution of choice (ie Syncthing, Resilio Sync, etc)
+* `STCS_TIMESTAMPS_DIR` should point to a local directory to store a timestamp of each game that's backed up.
+
+```bash
+mkdir ~/.local/share/CereSaves/
+cp stcs-global-config.sh ~/.local/share/CereSaves/
+cp stcs-wrapper.sh ~/.local/bin # Or anywhere else on the $PATH
+mkdir "$HOME/.local/share/CereSaves/Timestamps" # Or whatever you changed the value of STCS_TIMESTAMPS_DIR to be
+```
+
+## Usage
+* Place a copy of `stcs-config.sh.example` next to the game being executed.
+* Edit the file, removing the `.example` and filling out the gamename and the location of the savedata to back up. (It can be a file or folder of savedata)
+* Prefix any launch command you wish to invoke with `stcs-wrapper.sh`, similar to how you'd load `mangohud`!
