+# GUIDELINES
+
+This folder contains drivers for `LessonCategory`/`LessonCategories` 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/LessonCategories/type.d.tsx`
+
+simple template:
+
+```typescript
+import { pb } from '@/lib/pb';
+import { COL_LESSON_CATEGORIES } from '@/constants';
+
+export async function createLessonCategory(data: CreateFormProps) {
+  // ...content
+  // use direct return of pb.collection (e.g. return pb.collection(xxx))
+}
+```
