+There are a couple ways of doing this
+
+- Creating a shared library (only works if using shared libs)
+- Embeding the runtime
+- Forking crosslang and adding functionality (I don't support pull requests at this time)
+
+### Shared Library
+
+This assumes you are on linux, if on windows use MyPlugin.dll on mac libMyPlugin.dylib in crosslang project (it would be a good idea to check Env.Platform)
+
+CMakeLists.txt:
+```cmake
+cmake_minimum_required(VERSION 3.16)
+
+project(MyPlugin)
+
+find_package(TessesCrossLang REQUIRED)
+
+add_library(MyPlugin SHARED lib.cpp)
+
+target_link_libraries(MyPlugin PUBLIC TessesCrossLang::crosslang_shared)
+```
+
+lib.cpp:
+```c++
+#include <CrossLang.hpp>
+
+using namespace Tesses::CrossLang;
+
+void MyPlugin(GC* gc, TRootEnvironment* env)
+{
+    GCList ls(gc);
+    TDictionary* dict = TDictionary::Create(ls,{
+        TDItem("MyFunction", TExternalMethod::Create(ls, "A description for function",{"myLong","$optionalList"},[](GCList& ls, std::vector<TObject> args)->TObject {
+            int64_t n;
+            if(GetArgument(args,0,n))
+            {
+                TList* myLs;
+                if(GetArgumentHeap(args,1,myLs))
+                {
+                    //do something with the list
+                    myLs->Add(n);
+                    return TList::Create(ls, {n,myLs});
+                }
+
+
+                return TList::Create(ls, {n});
+            }
+
+            return nullptr;
+        }))
+    });
+
+    gc->BarrierBegin();
+    env->SetVariable("MyPlugin",dict);
+    gc->BarrierEnd();
+}
+
+CROSSLANG_PLUGIN(MyPlugin);
+
+```
+
+main.tcross:
+```go
+func main(args)
+{
+    Reflection.LoadNativePlugin(FS.MakeFull("libMyPlugin.so"));
+
+    var res = MyPlugin.MyFunction(42);
+    if(TypeOf(res) == "List")
+    {
+        Console.WriteLine(res);
+    }

+    if(TypeOf(res) == "List")
+    {

+
+
+### Embeding the runtime

+
+main.tcross (needs to be compiled with crossc):

+```
+
+### Forking (implementing it in runtime library itself)
+- edit include/CrossLang.hpp
+- in TStd class insert, static void RegisterMyPlugin(GC* gc, TRootEnvironment* env); where MyPlugin is whatever you want
+- edit src/runtime_methods/std.cpp
+- in TStd::RegisterStd before register everything call TStd::RegisterMyPlugin(gc, env);
+- in CMakeLists.txt within list(APPEND CROSSLANG_SOURCE **Many Source Files**) you must add src/runtime_methods/myplugin.cpp
+
+src/runtime_methods/myplugin.cpp:
+```c++
+#include <CrossLang.hpp>
+namespace Tesses::CrossLang 
+{
+    void TStd::RegisterMyPlugin(GC* gc, TRootEnvironment* env)
+    {
+        GCList ls(gc);
+        TDictionary* dict = TDictionary::Create(ls,{
+            TDItem("MyFunction", TExternalMethod::Create(ls, "A description for function",{"myLong","$optionalList"},[](GCList& ls, std::vector<TObject> args)->TObject {
+                int64_t n;
+                if(GetArgument(args,0,n))
+                {
+                    TList* myLs;
+                    if(GetArgumentHeap(args,1,myLs))
+                    {
+                        //do something with the list
+                        myLs->Add(n);
+                        return TList::Create(ls, {n,myLs});
+                    }
+
+
+                    return TList::Create(ls, {n});
+                }
+
+                return nullptr;
