 ### Known issues
 * CppExplorer may experience a `MissingMethodException` when trying to use certain UnityEngine methods. If you experience this, please open an issue and I will do my best to fix it.
+* Reflection may fail with certain types (eg. `Nullable<T>`, some Dictionary types, etc). Please see [Il2CppAssemblyUnhollower](https://github.com/knah/Il2CppAssemblyUnhollower#known-issues) for more details.
 * Scrolling with mouse wheel in the CppExplorer menu may not work on all games at the moment.

 * Allows you to inspect Properties, Fields and basic Methods, as well as set primitive values and evaluate primitive methods.
 * Can search and filter members for the ones you are interested in.

+## Building
+
+If you'd like to build this yourself, everything you need (other than MelonLoader) is included with this repository, there is no need for recursive cloning etc.
+
+1. Install MelonLoader for your game.
+2. Download this repository and open the `CppExplorer.sln` file in the `src` folder.
+3. In Visual Studio, right-click the CppExplorer C# Project in the solution browser and click "Unload Project".
+4. Right-click the "CppExplorer (unloaded)" and select "Edit Project File".
+5. Scroll down until you see the `<ItemGroup>` containing the References.
+6. Fix all of the paths in the `..\Steam\` directory for your game (use the full path if you need to).
+7. Reload the project and everything should be working, you can now build and run it.
