-# Upgrade v2.x to v3.0.0
-
-## Overview
-`megalodon` start Misskey support in version 3.0.0.
-In this update, there are few breaking changes, so please read this migration guide if you are using megalodon v2.x.
-
-There are three changes,
-
-1. Move class methods in Mastodon
-2. I prepare methods to call each Mastodon APIs
-3. Changed default export function
-
-
-
-## Move class methods in Mastodon
-In [#180](https://github.com/h3poteto/megalodon/pull/180), these methods are moved and changed to instance methods:
-
-- `registerApp`
-- `createApp`
-- `generateAuthUrl`
-- `fetchAccessToken`
-- `refreshToken`
-
-So please call these methods from Mastodon like:
-
-```typescript
-import { Mastodon } from 'megalodon'
-
-const client = new Mastodon(...)
-client.registerApp('TestApp')
-```
-
-## I prepare methods to call each Mastodon APIs
-In v2.x, probably you use `megalodon` like:
-
-```typescript
-import Mastodon from 'megalodon'
-
-const client = new Mastodon(...)
-
-client.get('/api/v1/timelines/home')
-
-```
-
-But these methods are deprecated, and are not exported from `megalodon` package.
-I prepared methods instead of these.
-
-There are all methods to call Mastodon APIs, so please use it.
-
-```typescript
-import { Mastodon } from 'megalodon'
-
-const client = new Mastodon(...)
-
-client.getHomeTimeline()
-```
-
-Please refer `megalodon` [document](https://h3poteto.github.io/megalodon/) for methods.
-
-## Changed default export function
-`megalodon` export `generator` function as default.
-This function generate Client API instance for specified SNS.
-
-```typescript
-import generator from 'megalodon'
-
-const client = generator(sns_name, url, access_token)
-```
-
-Now support `mastodon`, `pleroma` and `misskey` as sns parameter.
-
-
-And detector function is defined.
-This function detect which SNS's URL is provided.
-It returns SNS name, `mastodon`, `pleroma` or `misskey`.
-
-```typescript
-import { detector } from 'megalodon'
-
-const sns = await detector('https://mastodon.social')
-```
-
-These functions are necessary to treat multiple SNS.
-The smart way to call multiple SNS endpoint in same interface is:
-
-```typescript
-import generator, { detector } from 'megalodon'
-
-const sns = await detector(url)
-const client = generator(sns, url, access_token)
-
-client.getHomeTimeline()
-```
