+## Appsmith EE
+
+We use the `@appsmith` alias to switch files between CE and EE to avoid conflicts 
+during regular merging.  
+
+Steps to change something for the EE version of app
+
+- For the functionality you want to change the import statement in its consumers 
+to include the `@appsmith` import in the *CE repo*. For eg if you want to update the ApplicationCard
+ component will update this file of ApplicationList component.
+
+  *FROM*
+  ```typescript
+  // ApplicationList.tsx
+ 
+  import ApplicationCard from "./ApplicationCard";
+    
+  // OR 
+    
+  import ApplicationCard from "pages/Applications/ApplicationCard";  
+  ```
+  
+  *TO*
+  ```typescript
+  // ApplicationList.tsx 
+  
+  import ApplicationCard from "@appsmith/pages/Applications/ApplicationCard";
+  ```
+
+- Create a new file inside the *EE repo* called ApplicationCard with the same path
+    ```shell script
+    $ touch app/client/src/enterprise/pages/Applications/ApplicationCard
+    ```
+- EE will now use this file, so you can export a custom ApplicationCard component for EE.
+
+
+The goal is to reduce conflicts and have EE extend virtually any part of CE so selecting files to
+ update will be crucial. You should keep the following points in mind:
+ 
+ - NEVER update the CE file in the EE repo 
+ - All the consumers of the file will need it's expected exports.
+ - You can import from the CE file and reexport from your EE if no changes are expected. 
+ - The types of component props if different will cause problems in the component declaration and use. 
+ You can export that out these props into the `@appsmith` space to avoid this problem by reimplementing them in EE.
