+# Prisma Reader
+
+Reads Prisma schema files and extracts database schema information.
+
+## Overview
+
+The Prisma Reader parses `.prisma` schema files that define database models using Prisma's schema language and converts them into RelSpec's internal database model representation.
+
+## Features
+
+- Parses Prisma schema syntax
+- Extracts models, fields, and relationships
+- Supports Prisma attributes and directives
+- Handles enums and composite types
+
+## Usage
+
+### Basic Example
+
+```go
+package main
+
+import (
+    "fmt"
+    "git.warky.dev/wdevs/relspecgo/pkg/readers"
+    "git.warky.dev/wdevs/relspecgo/pkg/readers/prisma"
+)
+
+func main() {
+    options := &readers.ReaderOptions{
+        FilePath: "/path/to/schema.prisma",
+    }
+
+    reader := prisma.NewReader(options)
+    db, err := reader.ReadDatabase()
+    if err != nil {
+        panic(err)
+    }
+
+    fmt.Printf("Found %d schemas\n", len(db.Schemas))
+}
+```
+
+### CLI Example
+
+```bash
+# Read Prisma schema and convert to JSON
+relspec --input prisma --in-file schema.prisma --output json --out-file schema.json
+
+# Convert Prisma to GORM models
+relspec --input prisma --in-file schema.prisma --output gorm --out-file models.go
+```
+
+## Example Prisma Schema
+
+```prisma
+datasource db {
+  provider = "postgresql"
+  url      = env("DATABASE_URL")
+}
+
+generator client {
+  provider = "prisma-client-js"
+}
+
+model User {
+  id        Int      @id @default(autoincrement())
+  username  String   @unique @db.VarChar(50)
+  email     String   @db.VarChar(100)
+  createdAt DateTime @default(now()) @map("created_at")
+
+  posts Post[]
+
+  @@map("users")
+}
+
+model Post {
+  id      Int    @id @default(autoincrement())
+  userId  Int    @map("user_id")
+  title   String @db.VarChar(200)
+  content String @db.Text
+
+  user User @relation(fields: [userId], references: [id], onDelete: Cascade)
+
+  @@map("posts")
+}
+```
+
+## Supported Prisma Attributes
+
+- `@id` - Primary key
+- `@unique` - Unique constraint
+- `@default` - Default value
+- `@map` - Column name mapping
+- `@@map` - Table name mapping
+- `@relation` - Relationship definition
+- `@db.*` - Database-specific type annotations
+
+## Notes
+
+- Extracts datasource provider information
+- Supports `@@map` for custom table names
+- Handles Prisma-specific types and converts them to standard SQL types
