+## Using service accounts for uploading to avoid user rate limit
+For Service Account to work, you must set USE_SERVICE_ACCOUNTS="True" in config file or environment variables
+Many thanks to [AutoRClone](https://github.com/xyou365/AutoRclone) for the scripts
+**NOTE:** Using service accounts is only recommended while uploading to a team drive.
+
+## Generate service accounts [What is service account](https://cloud.google.com/iam/docs/service-accounts)
+
+Let us create only the service accounts that we need. 
+**Warning:** abuse of this feature is not the aim of this project and we do **NOT** recommend that you make a lot of projects, just one project and 100 sa allow you plenty of use, its also possible that over abuse might get your projects banned by google. 
+
+```
+Note: 1 service account can copy around 750gb a day, 1 project can make 100 service accounts so that's 75tb a day, for most users this should easily suffice. 
+```
+
+`python3 gen_sa_accounts.py --quick-setup 1 --new-only`
+
+A folder named accounts will be created which will contain keys for the service accounts
+
+NOTE: If you have created SAs in past from this script, you can also just re download the keys by running:
+```
+python3 gen_sa_accounts.py --download-keys project_id
+```
+
+## Add all the service accounts to the Team Drive
+- Run:
+```
+python3 add_to_team_drive.py -d SharedTeamDriveSrcID
+```
+
+## Youtube-dl authentication using .netrc file
+For using your premium accounts in youtube-dl, edit the netrc file (in the root directory of this repository) according to following format:
+```
+machine host login username password my_youtube_password
+```
+where host is the name of extractor (eg. youtube, twitch). Multiple accounts of different hosts can be added each separated by a new line
