 # Theia - Core extension
 
+See [here](https://www.theia-ide.org/doc/index.html) for a detailed documentation.
+
+## Theia Extension
+
+A Theia extension is a node package declaring `theiaExtensions` property in `package.json`:
+
+```json
+{
+  "theiaExtensions": [{
+      "frontend": "lib/myExtension/browser/myextension-frontend-module",
+      "backend": "lib/myExtension/node/myextension-backend-module",
+    }, {
+      "frontend": "lib/myExtension2/browser/myextension2-browser-module",
+      "frontendElectron": "lib/myExtension2/electron-browser/myextension2-electron-browser-module",
+      "backend": "lib/myExtension2/node/myextension2-node-module",
+      "backendElectron": "lib/myExtension2/electron-main/myextension2-electron-main-module"
+  }]
+}
+```
+
+Each extension can consist of the following modules:
+- `frontend` is used in the browser env and as well in the electron if `frontendElectron` is not provided
+- `frontendElectron` is used in the electron env
+- `backend` is used in the node env and as well in the electron env if `backendElectron` is not provided
+- `backendElectron` is used in the electron env
+
+An extension module should have a default export of `ContainerModule | Promise<ContainerModule>` type.
+
+## Theia Application
+
+A Theia application is a node package listing [Theia extensions](#theia-extension) as dependencies and managed with [Theia CLI](../../dev-packages/cli/README.md).
+
 ## Logging configuration
 
 It's possible to change the log level for the entire Theia application by
