+  - [Table of Contents](#table-of-contents)
+  - [Minimum Requirements](#minimum-requirements)

+  - [Settings](#settings)
+
+## Minimum Requirements
+
+To run Xvirus SDK you need:
+
+- .NET 5 Runtime - [download](<[https://link](https://dotnet.microsoft.com/download/dotnet/thank-you/runtime-5.0.11-windows-x64-installer)>)
+- Visual C++ Redistributable 2019 - [download](https://aka.ms/vs/16/release/vc_redist.x64.exe)
+
+## Changelog
+
+- Completely redone in .NET 5
+- Now supports Linux (CLI and C# bindings only)
+- Added XvirusAI scan engine (BETA)
+- Scan speed is up to 2x faster
+- Fixed memory usage spike when scanning large files
+- Removed file size limit for scanned files by default
+- The checkUpdate function can now check for SDK updates
+- Added 3 new settings "EnableAIScan", "MaxScanLength" and "DatabaseVersion"
+
+## Known Issues
+
+- XvirusAI engine is still in BETA. It is not recomended to use in production yet.
+- The checkUpdate function can now check for SDK updates but can't update it
+
+## Get Started
+
+The "`example`" folder contains an example project on how to import and use Xvirus SDK in C++.
+
+This project shows you how to statically load Xvirus SDK using `xvneng.lib`, you can also dinamically load `xvneng.dll` like any other dll, [see](https://stackoverflow.com/questions/8696653/dynamically-load-a-function-from-a-dll).
+
+You can run it by building it, copying the files from the `bin` folder to the output folder of the build and then running `xvbdc.exe`.
+
+## Avaiable Functions
+
+You can find the declaration of all functions and structs in the file `xvneng.h` located in the "headers" folder.
+
+- **load** - Loads Xvirus Scan Engine into memory, if set `force`=true it will reload the scan engine, even if it is already loaded.
+- **unload** - Unloads Xvirus Scan Engine from memory.
+- **scan** - Scans the file located at `filepath`. It will return a [`ScanResult`](#Model).
+- **scanAsString** - Scans the file located at `filepath`. It will return one of the following strings:
+  - "**Safe**" - If no malware is detected.
+  - "**Malware**" - If malware is detected but the name isn't known.
+  - **_Malware Name_** - If it is malware from a known family (example: "Trojan.Downloader").
+  - "**AI.{aiScore}**" - Score of the file using XvirusAI from 0 to 100, the higher the score the more probable it is malicious (example: "AI.99").
+  - "**File not found!**" - If no file is found in the submited path.
+  - "**File too big!**" - If the file size is bigger than the set limit.
+  - "**Could not get file hash!**" - There was an error calculating the hash of the file.
+- **checkUpdates** - Checks and updates the databases and AI engine to the most recent versions. If `checkSDKUpdates`=true then it will also check for SDK updates. If `loadDBAfterUpdate`=true then it will reload the Xvirus Scan Engine after the update is done. It can return the following strings:
+  - "**There is a new SDK version available!**"
+  - "**Database was updated!**"
+  - "**Database is up-to-date!**"
+- **getSettings** - returns a string representation of the `settings.json` file.
+- **version** - returns the version of the SDK/CLI.
+
+![functions](./functions.JPG)
+
+## Model
+
+The `scan` function returns a struct `ScanResult` with the following properties:
+
+```c++
+struct ScanResult {
+	bool isMalware; // true if malware
+	double score; // between 0 and 1, higher score means more likely to be malware, -1 if there was an error
+	char* name; // detection name
+};
+```
+
+## Settings
+
+Settings are located in the "`settings.json`" file in the root folder of the SDK. There are 4 avaiable options:
+
+- **EnableHeuristics** - Enables heuristics scanning of files. Default: _true_
+- **EnableAIScan** - Enables XvirusAI scan engine. This feature is still in BETA. Default: _false_
+- **MaxScanLength** - Maximum file size to be scanned in bytes. If set "null" then there is no limit. Default: _null_
+- **DatabaseVersion** - KeyValue list of database files version. This is updated automatically when using the "checkUpdate()" function.
+
+Example of a `settings.json` file:
+
+```JSON
+{
+  "EnableHeuristics": true,
+  "EnableAIScan": false,
+  "MaxScanLength": null,
+  "DatabaseVersion": {
+    "AIModel": 0,
+    "MainDB": 0,
+    "DailyDB": 0,
+    "WhiteDB": 0,
+    "DailywlDB": 0,
+    "HeurDB": 0,
+    "HeurDB2": 0,
+    "MalvendorDB": 0
+  }
+}
+```
+
+## Exceptions
+
+If any of the functions fail it may return an [exception](https://www.cplusplus.com/doc/tutorial/exceptions/).
+
+All exceptions are logged in the `errorlog.txt` file.
