+This document contains instructions for migrating to various storage versions.
+
+### 0.1 -> 0.2
+v0.2 fixes [a bug](https://github.com/gofiber/fiber/issues/1258) in MYSQL, Postgres and Arangodb in which 
+inserting non-UTF8 characters would trigger a panic due to the values being saved in a TEXT column instead of a 
+BYTEA/BLOB column. Migration instructions (note you may need to adjust the table names if you have supplied a custom
+config to the storage):
+
+**Postgres**
+```sql
+ALTER TABLE fiber_storage
+ALTER COLUMN v TYPE BYTEA USING v::bytea;
+```
+
+**MYSQL**
+```sql
+ALTER TABLE fiber_storage MODIFY COLUMN v BLOB;
+```
+
+**Arangodb**
+
+No migration other then updating the library is necessary.

+func (s *Storage) Get(key string) ([]byte, error)
+func (s *Storage) Set(key string, val []byte, exp time.Duration) error
+func (s *Storage) Delete(key string) error
+func (s *Storage) Reset() error
+func (s *Storage) Close() error
+```
+### Installation
+ArangoDB is tested on the 2 last (1.14/1.15) [Go versions](https://golang.org/dl/) with support for modules. So make sure to initialize one first if you didn't do that yet:
+```bash
+go mod init github.com/<user>/<repo>
+```
+And then install the mysql implementation:
+```bash
+go get github.com/gofiber/storage/arangodb
+```
+
+### Examples
+Import the storage package.
+```go
+import "github.com/gofiber/storage/arangodb"
+```
+
+You can use the following possibilities to create a storage:
+```go
+// Initialize default config
+store := arangodb.New()
+
+// Initialize custom config
+store := arangodb.New(arangodb.Config{
+	Host:       "http://127.0.0.1",
+	Port:       8529,
+	Database:   "fiber",
+	Collection: "fiber_storage",
+	Reset:      false,
+	GCInterval: 10 * time.Second,
+})
+```
+
+### Config
+```go
+type Config struct {
+	// Host name where the DB is hosted
+	//
+	// Optional. Default is "http://127.0.0.1"
+	Host string
+
+	// Port where the DB is listening on
+	//
+	// Optional. Default is 8529
+	Port int
+
+	// Server username
+	//
+	// Optional. Default is ""
+	Username string
+
+	// Server password
+	//
+	// Optional. Default is ""
+	Password string
+
+	// Database name
+	//
+	// Optional. Default is "fiber"
+	Database string
+
+	// Collection name
+	//
+	// Optional. Default is "fiber_storage"
+	Collection string
+
+	// Reset clears any existing keys in existing collection
+	//
+	// Optional. Default is false
+	Reset bool
+	// Time before deleting expired keys
+	//
+	// Optional. Default is 10 * time.Second
+	GCInterval time.Duration
+}
+```
+
+### Default Config
+Used only for optional fields
+```go
+var ConfigDefault = Config{
+	Host:       "http://127.0.0.1",
+	Port:       8529,
+	Database:   "fiber",
+	Collection: "fiber_storage",

 ### Installation
+
 Badger is tested on the 2 last [Go versions](https://golang.org/dl/) with support for modules. So make sure to initialize one first if you didn't do that yet:
+
 ```bash
 go mod init github.com/<user>/<repo>
 ```
+
 And then install the badger implementation:
+
 ```bash
 go get github.com/gofiber/storage/badger
 ```
 
 ### Examples
+
 Import the storage package.
+
 ```go
 import "github.com/gofiber/storage/badger"
 ```
 
 You can use the following possibilities to create a storage:

 ```go
 // Initialize default config
 store := badger.New()

+# Bbolt
+A Bbolt storage driver using [etcd-io/bbolt](https://github.com/etcd-io/bbolt). Bolt is a pure Go key/value store inspired by [Howard Chu's](https://twitter.com/hyc_symas) [LMDB project](https://www.symas.com/symas-embedded-database-lmdb). The goal of the project is to provide a simple, fast, and reliable database for projects that don't require a full database server such as Postgres or MySQL.

+func (s *Storage) Get(key string) ([]byte, error)
+func (s *Storage) Set(key string, val []byte, exp time.Duration) error
+func (s *Storage) Delete(key string) error
+func (s *Storage) Reset() error
+func (s *Storage) Close() error
+```
+### Installation
+Bbolt is tested on the 2 last [Go versions](https://golang.org/dl/) with support for modules. So make sure to initialize one first if you didn't do that yet:
+```bash
+go mod init github.com/<user>/<repo>
+```
+And then install the s3 implementation:
+```bash
+go get github.com/gofiber/storage/bbolt
+```
+
+### Examples
+Import the storage package.
+```go
+import "github.com/gofiber/storage/bbolt"
+```
+
+You can use the following possibilities to create a storage:
+```go
+// Initialize default config
+store := bbolt.New()
+
+// Initialize custom config
+store := bbolt.New(bbolt.Config{
+	Database: "my_database.db",
+	Bucket:   "my-bucket",
+	Reset:    false,
+})
+```
+
+### Config
+```go
+// Config defines the config for storage.
+type Config struct {
+	// Database path
+	//
+	// Optional. Default is "fiber.db"
+	Database string
+
+	// Bbolt bucket name
+	//
+	// Optional. Default is "fiber_storage"
+	Bucket string
+
+	// Timeout is the amount of time to wait to obtain a file lock.
+	// Only available on Darwin and Linux.
+	//
+	// Optional. Default is 0 (no timeout)
+	Timeout time.Duration
+
+	// Open database in read-only mode.
+	//
+	// Optional. Default is false
+	ReadOnly bool
+
+	// Reset clears any existing keys in existing Bucket
+	//
+	// Optional. Default is false
+	Reset bool
+}
+```
+
+### Default Config
+```go
+// ConfigDefault is the default config
+var ConfigDefault = Config{
+	Database: "fiber.db",
+	Bucket:   "fiber_storage",
+	Timeout:  0,
+	ReadOnly: false,
+	Reset:    false,
+}
+```

+# Ristretto
+
+A Memory-bound storage driver using [`dgraph-io/ristretto`](https://github.com/dgraph-io/ristretto).
+

+- [Signatures](#signatures)
+- [Installation](#installation)
+- [Examples](#examples)
+- [Config](#config)
+- [Default Config](#default-config)
+
+
+### Signatures
+```go
+func New(config ...Config) Storage
+func (s *Storage) Get(key string) ([]byte, error)
+func (s *Storage) Set(key string, val []byte, exp time.Duration) error
+func (s *Storage) Delete(key string) error
+func (s *Storage) Reset() error
+func (s *Storage) Close() error
+```
+
+### Installation
+Ristretto is tested on the 2 last [Go versions](https://golang.org/dl/) with support for modules. So make sure to initialize one first if you didn't do that yet:
+```bash
+go mod init github.com/<user>/<repo>
+```
+And then install the ristretto implementation:
+```bash
+go get github.com/gofiber/storage/ristretto
+```
+
+### Examples
+Import the storage package.
+```go
+import "github.com/gofiber/storage/ristretto"
+```
+
+You can use the following possibilities to create a storage:
+```go
+// Initialize default config
+store := ristretto.New()
+
+// Initialize custom config
+store := ristretto.New(ristretto.Config{
+  NumCounters: 1e7, // number of keys to track frequency of (10M).
+  MaxCost:     1 << 30, // maximum cost of cache (1GB).
+  BufferItems: 64, // number of keys per Get buffer.
+})
+```
+
+### Config
+```go
+type Config struct {
+  // NumCounters number of keys to track frequency of (10M).
+  NumCounters int64
+
+  // MaxCost maximum cost of cache (1GB).
+  MaxCost     int64
+
+  // BufferItems number of keys per Get buffer.
+  BufferItems int64
+}
+```
+
+### Default Config
+```go
+var ConfigDefault = Config{
+  NumCounters: 1e7,
+  MaxCost:     1 << 30,
+  BufferItems: 64,
+  DefaultCost: 1,
+}
+```

+# S3
+
+A S3 storage driver using [aws/aws-sdk-go-v2](https://github.com/aws/aws-sdk-go-v2).
+
+**Note:** If config fields of credentials not given, credentials are using from the environment variables, ~/.aws/credentials, or EC2 instance role. If config fields of credentials given, credentials are using from config. Look at: [specifying credentials](https://aws.github.io/aws-sdk-go-v2/docs/configuring-sdk/#specifying-credentials)

+func New(config ...Config) Storage
+func (s *Storage) Get(key string) ([]byte, error)
+func (s *Storage) Set(key string, val []byte, exp time.Duration) error
+func (s *Storage) Delete(key string) error
+func (s *Storage) Reset() error
+func (s *Storage) Close() error
+```
+### Installation
+S3 is tested on the 2 last [Go versions](https://golang.org/dl/) with support for modules. So make sure to initialize one first if you didn't do that yet:
+```bash
+go mod init github.com/<user>/<repo>
+```
+And then install the s3 implementation:
+```bash
+go get github.com/gofiber/storage/s3
+```
+
+### Examples
+Import the storage package.
+```go
+import "github.com/gofiber/storage/s3"
+```
+
+You can use the following possibilities to create a storage:
+```go
+// Initialize default config
+store := s3.New()
+
+// Initialize custom config
+store := s3.New(s3.Config{
+	Bucket:   "my-bucket-url",
+	Endpoint: "my-endpoint",
+	Region:   "my-region",
+	Reset:    false,
+})
+```
+
+### Config
+```go
+// Config defines the config for storage.
+type Config struct {
+	// S3 bucket name
+	Bucket string
+
+	// AWS endpoint
+	Endpoint string
+
+	// AWS region
+	Region string
+
+	// Request timeout
+	//
+	// Optional. Default is 0 (no timeout)
+	RequestTimeout time.Duration
+
+	// Reset clears any existing keys in existing Bucket
+	//
+	// Optional. Default is false
+	Reset bool
+
+    // Credentials overrides AWS access key and AWS secret access key. Not recommended.
+	//
+	// Optional. Default is Credentials{}
+	Credentials Credentials
+
+	// The maximum number of times requests that encounter retryable failures should be attempted.
+	//
+	// Optional. Default is 3
+	MaxAttempts int
+
+}
+
+type Credentials struct {
+	AccessKey       string
+	SecretAccessKey string
+}
+```
+
+### Default Config
+The default configuration lacks Bucket, Region, and Endpoint which are all required and must be overwritten:
+```go
+// ConfigDefault is the default config
+var ConfigDefault = Config{
+	Bucket:         "",
+	Region:         "",
+	Endpoint:       "",
+	Credentials:    Credentials{},
+	MaxAttempts:    3,
+	RequestTimeout: 0,
+	Reset:          false,
+}
+```
