-# ThreadPool
+# Thread pool module
 
 A c++ Godot engine module, that will help you with threading.
+
+It can also work if threads are not available (like on the javascript backend), in this case it runs jobs on the 
+main thread. Jobs themselves can also distribute their work onto multiple frames, and you can set how much time 
+is allocated per frame.
+
+You can access it's setting from the `Project->Project Settings...` menu, ont the `ThreadPool` category.
+
+# Pre-built binaries
+
+You can grab a pre-built editor binary from the [Broken Seals](https://github.com/Relintai/broken_seals/releases) 
+repo, should you want to. It contains all my modules.
+
+# ThreadPolJob
+
+Contains a job that can run on different threads.
+
+A job is only considered finished, if you set the 'complete' property to 'true'. If multiple threads are available, 
+the system will not check for this though, because there is no need.
+
+If you want to support envioronment that doesn't have threading, you can use 
+
+```
+bool should_do(const bool just_check = false);
+bool should_return();
+```
+helpers.
+
+For example:
+
+```
+func _execute():
+    # On the first run this will always return, true, on the subsequest runs it will return false
+    if should_do():
+        thing1()
+
+    # if you ran out the allocated timeframe in a frame, this will return true
+    if should_return():
+        return
+
+    if should_do():
+        thing2()
+
+    complete = true
+
+```
+
+`should_do`'s optional parameter will let you just query the system, whether you finished a step, without
+incrementing internal couters.
+
+This class will need litle tweaks, hopefully I can get to is soon.
+
+# ThreadPoolExecuteJob
+
+This will let you run a method uin an another thread, without creating your own jobs.
+
+Use it through the ThreadPool Singleton. Like:
+
+```
+ThreadPool.create_execute_job(self, "method", arg1, arg2, ...)
+
+#or
+ThreadPool.create_execute_job_simple(self, "method")
+```
+
+This class will need litle tweaks, hopefully I can get to is soon.
+
+# ThreadPool singleton
+
+The ThreadPool singleton handles jobs.
+
+If you have a job, submit it using `add_job`:
+
+```
+MyJob job = MyJob.new()
+ThreadPool.add_job(job)
+```
+
+It's api is still a bit messy, it will be cleaned up (hopefully very soon).
+
+# Building
+
+1. Get the source code for the engine.
+
+If you want Godot 3.2:
+```git clone -b 3.2 https://github.com/godotengine/godot.git godot```
+
+If you want Godot 4.0:
+```git clone https://github.com/godotengine/godot.git godot```
+
+
+2. Go into Godot's modules directory.
+
+```
+cd ./godot/modules/
+```
+
+3. Clone this repository
+
+```
+git clone https://github.com/Relintai/thread_pool thread_pool
+```
+
+4. Build Godot. [Tutorial](https://docs.godotengine.org/en/latest/development/compiling/index.html)
