-# msauth
-
-## Introduction
-
-Very simple package to authorize applications against [Microsoft identity platform].
-
-It utilizes [v2.0 endpoint] so that it can authorize users using both personal (Microsoft) and organizational (Azure AD) account.
-
-## Usage
-
-### Device authorization grant
-
-- [OAuth 2.0 device authorization grant flow]
-
-```go
-const (
-	tenantID     = "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"
-	clientID     = "YYYYYYYY-YYYY-YYYY-YYYY-YYYYYYYYYYYY"
-	tokenCachePath  = "token_cache.json"
-)
-
-var scopes = []string{"openid", "profile", "offline_access", "User.Read", "Files.Read"}
-
-	ctx := context.Background()
-	m := msauth.NewManager()
-	m.LoadFile(tokenCachePath)
-	ts, err := m.DeviceAuthorizationGrant(ctx, tenantID, clientID, scopes, nil)
-	if err != nil {
-		log.Fatal(err)
-	}
-	m.SaveFile(tokenCachePath)
-
-	httpClient := oauth2.NewClient(ctx, ts)
-	...
-```
-
-### Client credentials grant
-
-- [OAuth 2.0 client credentials grant flow]
-
-```go
-const (
-	tenantID     = "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"
-	clientID     = "YYYYYYYY-YYYY-YYYY-YYYY-YYYYYYYYYYYY"
-	clientSecret = "ZZZZZZZZZZZZZZZZZZZZZZZZ"
-)
-
-var scopes = []string{msauth.DefaultMSGraphScope}
-
-	ctx := context.Background()
-	m := msauth.NewManager()
-	ts, err := m.ClientCredentialsGrant(ctx, tenantID, clientID, clientSecret, scopes)
-	if err != nil {
-		log.Fatal(err)
-	}
-
-	httpClient := oauth2.NewClient(ctx, ts)
-    ...
-```
-
-### Authorization code grant
-
-- [OAuth 2.0 authorization code grant flow]
-- Not yet implemented.
