+# Configuration
+
+`rem-essentials` uses one active runtime configuration and, when the REM
+Launcher is used, one persistent user override file.
+
+## Configuration files
+
+### Active game configuration
+
+The DLL reads only this file at game startup:
+
+```text
+Freelancer/EXE/rem-essentials.ini
+```
+
+The file is shipped with the mod and contains the complete setting schema,
+descriptions, metadata, and release defaults. A manual installation only needs
+this INI and `rem-essentials.dll` in the `EXE` directory.
+
+If the active INI is missing, the DLL uses its compiled defaults. The compiled
+defaults intentionally match the shipped INI, but distributing the INI is
+recommended because it exposes every feature and typed parameter.
+
+### Launcher user overrides
+
+The REM Launcher stores player choices separately:
+
+```text
+My Games/REM/rem-essentials.user.ini
+```
+
+On Wine or Proton, `My Games` is inside the Windows user profile of the active
+prefix. Its exact Linux path depends on how the Launcher or game prefix was
+created.
+
+The DLL does not read this user file. The Launcher merges matching values from
+the user file into `Freelancer/EXE/rem-essentials.ini`:
+
+- after a game/mod update
+- after saving settings in the Launcher
+- immediately before starting Freelancer
+
+This allows an update to replace the shipped schema while retaining player
+choices. New settings from an updated default INI appear automatically. Values
+from the user override win when the same section and key exist in both files.
+
+## Value precedence
+
+At runtime, the effective value is determined in this order:
+
+1. The compiled DLL fallback is used when no setting can be read.
+2. `Freelancer/EXE/rem-essentials.ini` overrides the compiled fallback.
+3. Before launch, the Launcher materializes values from
+   `rem-essentials.user.ini` into the active INI.
+
+For a manual installation without the Launcher, only the first two levels
+apply. Editing the active INI is therefore sufficient.
+
+## Sections and value types
+
+Feature switches live in `[rem-essentials]`. Parameters used by migrated
+flplusplus behavior live in `[flplusplus]`.
+
+Boolean values accept:
+
+```text
+true / false
+1 / 0
+yes / no
+on / off
+```
+
+Integer, float, and string settings are described by the comments immediately
+above each key. Metadata such as `type`, `min`, `max`, `default`, `group`, and
+`risk` is also used by the Launcher to build the settings UI.
+
+## Save directory behavior
+
+REM keeps the historical installation-local save directory as its default:
+
+```ini
+[rem-essentials]
+save_path_feature = true
+
+[flplusplus]
+save_in_directory = true
+save_folder_name = Freelancer
+```
+
+With `save_in_directory = true`, the patched path is calculated relative to
+`Freelancer.exe`:
+
+```text
+Freelancer/EXE/../SAVE
+```
+
+For an installation such as:
+
+```text
+/home/<user>/Schreibtisch/RemLauncher_AppData/current/Freelancer/EXE/Freelancer.exe
+```
+
+the effective save directory is:
+
+```text
+/home/<user>/Schreibtisch/RemLauncher_AppData/current/Freelancer/SAVE
+```
+
+With `save_in_directory = false`, the plugin instead uses the Windows
+Documents folder exposed by Windows, Wine, or Proton and appends:
+
+```text
+My Games/<save_folder_name>
+```
+
+`save_folder_name` is therefore only relevant when
+`save_in_directory = false`. Setting `save_path_feature = false` disables this
+hook completely and restores Freelancer's unpatched path behavior.
+
+Changing the setting does not move existing saves. Move existing files to the
+selected directory before launching when switching between layouts.
+
+## Manual installation
+
+1. Copy `rem-essentials.dll` and `rem-essentials.ini` into `Freelancer/EXE`.
+2. Add `rem-essentials.dll` to the appropriate `[Libraries]` section in
+   `dacom.ini` and, for FLServer features, `dacomsrv.ini`.
+3. Ensure `save_path_feature = true` and `save_in_directory = true` for the REM
+   installation-local `SAVE` layout.
+4. Fully restart Freelancer after changing the INI. Settings are read when the
+   DLL is loaded.
+
+## Launcher-managed installation
+
+Use the Game Settings page to change supported values. Saving creates or
+updates `My Games/REM/rem-essentials.user.ini`. Avoid manually changing the
+active INI while a conflicting user override exists, because the Launcher will
+materialize the user value again before game startup.
