+# Get Started
+
+Welcome to the comprehensive guide to plugin development in Flow Launcher.
+
+## Types of plugin implementation
+
+While Flow Launcher is written in C#, plugins can be written natively or in other languages.
+
+### Natively (no intergration needed)
+
+- [**C# (.NET framework)**](/develop-dotnet-plugins.md)
+
+### Using JSON-RPC
+
+For other languages, Flow launcher communicates with the plugin via [JSON-RPC](/json-rpc.md).
+
+Currently supported languages are:
+
+- [**Python**](/py-develop-plugins.md)
+- [**JavaScript / TypeScript (NodeJS)**](/nodejs-develop-plugins.md)

+### Testing your plugin
+
+After successfully building a plugin, it can be tested locally by moving the output files into Flow Launcher's `FlowLauncher\Plugins` directory accessible via the `userdata` command in Flow Launcher. Alternatively, if you are building .Net (C# or F#) plugins you can have your IDE build the artefact directly to that location (remember not to check this build output path into Git though). 
+
+
+### Detail Steps
+
+1. Execute `userdata` in Flow Launcher.
+2. Navigate into the `Plugins` folder.
+3. Move exisiting plugin with the same `Plugin ID` as specify in `plugin.json` away from the folder (_**if more than one plugin have the same `Plugin ID`, none of them will be loaded**_).
+4. Copy and paste the newly built plugin folder into this folder.
+5. Execute `Restart Flow Launcher` to reload the new plugin.
+
+Tip: .Net plugins (e.g. C# and F#) will require you to restart flow every time you make a change and build a new artefact to reload the plugin, but Python and JS/TS plugins you can edit the plugin directly.
