-# GUIDELINES
-
-This folder contains drivers for `User`/`Users` records using PocketBase:
-
-- create (Create.tsx)
-- read (GetById.tsx)
-- write (Update.tsx)
-- count (GetAllCount.tsx)
-- delete (Delete.tsx)
-- list (GetAll.tsx)
-
-the `@` sign refer to `/home/logic/_wsl_workspace/001_github_ws/lettersoup-online-ws/lettersoup-online/project/002_source/cms/src`
-
-## Assumption and Requirements
-
-- assume `pb` is located in `@/lib/pb`
-- no need to handle error in this function, i'll handle it in the caller
-- type information defined in `@/db/Users/type.d.tsx`
-
-simple template:
-
-```typescript
-import { pb } from '@/lib/pb';
-import { COL_USERS } from '@/constants';
-
-export async function createUser(data: CreateFormProps) {
-  // ...content
-  // use direct return of pb.collection (e.g. return pb.collection(xxx))
-}
-```
