+# Store
+
+The store provides a pluggable interface for data storage in Go Micro.
+
+## Features
+- Key-value storage
+- Multiple backend support
+
+## Implementations
+Supported stores include:
+- Memory (default)
+- File (`go-micro.dev/v6/store/file`)
+- MySQL (`go-micro.dev/v6/store/mysql`)
+- Postgres (`go-micro.dev/v6/store/postgres`)
+- NATS JetStream KV (`go-micro.dev/v6/store/nats-js-kv`)
+
+Plugins are scoped under `go-micro.dev/v6/store/<plugin>`.
+
+Configure the store in code or via environment variables.
+
+## Example Usage
+
+Here's how to use the store in your Go Micro service:
+
+```go
+package main
+
+import (
+    "go-micro.dev/v6"
+    "go-micro.dev/v6/store"
+    "log"
+)
+
+func main() {
+    service := micro.NewService("store-example")
+    service.Init()
+
+    // Write a record
+    if err := store.Write(&store.Record{Key: "foo", Value: []byte("bar")}); err != nil {
+        log.Fatal(err)
+    }
+
+    // Read a record
+    recs, err := store.Read("foo")
+    if err != nil {
+        log.Fatal(err)
+    }
+    log.Printf("Read value: %s", string(recs[0].Value))
+}
+```
+
+## Configure a specific store in code
+
+Postgres:
+```go
+import (
+    "go-micro.dev/v6"
+    postgres "go-micro.dev/v6/store/postgres"
+)
+
+func main() {
+    st := postgres.NewStore()
+    svc := micro.NewService("store-example", micro.Store(st))
+    svc.Init()
+    svc.Run()
+}
+```
+
+NATS JetStream KV:
+```go
+import (
+    "go-micro.dev/v6"
+    natsjskv "go-micro.dev/v6/store/nats-js-kv"
+)
+
+func main() {
+    st := natsjskv.NewStore()
+    svc := micro.NewService("store-example", micro.Store(st))
+    svc.Init()
+    svc.Run()
+}
+```
+
+## Configure via environment
+
+```bash
+MICRO_STORE=postgres MICRO_STORE_ADDRESS=postgres://user:pass@127.0.0.1:5432/db \
+MICRO_STORE_DATABASE=micro MICRO_STORE_TABLE=micro \
+go run main.go
+```
+
+Common variables:
+- `MICRO_STORE`: selects the store implementation (`memory`, `file`, `mysql`, `postgres`, `nats-js-kv`).
+- `MICRO_STORE_ADDRESS`: connection/address string for the store (plugin-specific format).
+- `MICRO_STORE_DATABASE`: logical database or namespace (plugin-specific).
+- `MICRO_STORE_TABLE`: logical table/bucket (plugin-specific).
