Bucket Creation
Now, that you have setup your RustFS instance and are logged in with a new user account you can start creating your buckets that you can use for other applications to store data in. 
Go to Browser
Then click on + Create Bucket
Give it a name
Access Keys
After you have created a bucket you should create access keys credentials that will allow you to access the buckets through one of your applications. 
Go to Access Keys
Create a new Key pair
Make sure you save the file or the secret key in Bitwarden or any other password manager
Bucket Information File
So after you have created a bucket and you have set up an access key then you are ready to attach it to an application. By default it can ask for the following credentials
S3 Endpoint: This is your HTTPS domain name in the case of a public instance or IP-RustFSVM:9001 
Region: If you have only one location than you can leave this blank 
Bucket Name: Well the Bucket name 
Directory: This is directory inside the bucket if you have setup directories in there. Otherwise just use root which is provided with the / symbol  
Access Key: That is the access key you created
Secrety Key: The secret key you created and obtained while making the access key 
All of these are the ones you can possibly fill in for your environment variables in your docker compose file or directly through the WebUI if the applications allows for it.
