+## What is SMAPI?
+**SMAPI** is an [open-source](LICENSE) modding API for [Stardew Valley](http://stardewvalley.net/)
+that lets you play the game with mods. It's safely installed alongside the game's executable, and
+doesn't change any of your game files. It serves five main purposes:
+
+1. **Load mods into the game.**
+ _SMAPI loads mods when the game is starting up so they can interact with it. (Code mods aren't
+ possible without SMAPI to load them.)_
+
+2. **Provide APIs and events for mods.**
+ _SMAPI provides low-level APIs and events which let mods interact with the game in ways they
+ otherwise couldn't._
+
+3. **Rewrite mods for crossplatform compatibility.**
+ _SMAPI rewrites mods' compiled code before loading them so they work on Linux/Mac/Windows
+ without the mods needing to handle differences between the Linux/Mac and Windows versions of the
+ game._
+
+4. **Rewrite mods to update them.**
+ _SMAPI detects when a mod accesses part of the game that changed in a recent update which
+ affects many mods, and rewrites the mod so it's compatible._
+
+5. **Intercept errors.**
+ _SMAPI intercepts errors that happen in the game, displays the error details in the console
+ window, and in most cases automatically recovers the game. This prevents mods from accidentally
+ crashing the game, and makes it possible to troubleshoot errors in the game itself that would
+ otherwise show a generic 'program has stopped working' type of message._
+

## Advanced usage
### Configuration file
You can customise the SMAPI behaviour by editing the `StardewModdingAPI.config.json` file in your
-game folder. If it's missing, it'll be generated automatically next time SMAPI runs. It contains
-these fields:
+game folder. It contains these fields:
field | purpose
----- | -------
`DeveloperMode` | Default `false` (except in _SMAPI for developers_ releases). Whether to enable features intended for mod developers. Currently this only makes `TRACE`-level messages appear in the console.
`CheckForUpdates` | Default `true`. Whether SMAPI should check for a newer version when you load the game. If a new version is available, a small message will appear in the console. This doesn't affect the load time even if your connection is offline or slow, because it happens in the background.
+`ModCompatibility` | A list of mod versions SMAPI should consider compatible or broken regardless of whether it detects incompatible code. Each record can be set to `AssumeCompatible` or `AssumeBroken`. Changing this field is not recommended and may destabilise your game.
### Command-line arguments
-SMAPI recognises the following command-line arguments. These are intended for internal use and may

+SMAPI recognises the following command-line arguments. These are intended for internal use or

argument | purpose
-------- | -------
+`--log path "path"` | The relative or absolute path of the log file SMAPI should write.
`--no-terminal` | SMAPI won't write anything to the console window. (Messages will still be written to the log file.)
