 So, what does importing and exporting functions from a plugin look like in practice? I'm glad you asked...
 
 ## Creating new plugins

 A plugin is just a rust crate like any other. All plugins embedded in Zed are located in the `plugins` folder in the root. These plugins will automatically be compiled, optimized, and recompiled on change, so it's recommended that when creating a new plugin you create it there.

 Currently, plugins are used to add support for language servers to Zed. Plugins should be fairly simple to integrate for library-like applications. Here's a quick overview of how plugins work:

 > **Note**: This is a limitation of the WebAssembly standard itself. In the future, to work around this, we've been considering starting a pool of plugins, or instantiating a new plugin per call (this isn't as bad as it sounds, as instantiating a new plugin only takes about 30µs).
