+
+
+🗂 Upload a File
+ +1. Navigate to the _Spaces_ section +2. Select _Details_ on the target Space/Bucket +3. Click on _Upload File_ +4. Pick our file, provide a name and click _Submit_ +5. A message should pop up to indicate success +
+
+
+🔎 List all Objects in a Bucket
+ +1. Navigate to the _Spaces_ section +2. Select _Details_ on the target Space/Bucket +3. You see a list of all objects stored in the bucket +
+
+
+🌐 Get an Object's URL

+
+
+📢 Make an object public
+ +1. Navigate to the _Spaces_ section +2. Select _Details_ on the target Space/Bucket +3. Select _Make Public_ on the target object +4. A message should pop up to indicate success +
+
+
+🤫 Make an Object private
+ +1. Navigate to the _Spaces_ section +2. Select _Details_ on the target Space/Bucket +3. Select _Make Private_ on the target object +4. A message should pop up to indicate success +
+
+
+🔥 Delete an Object
+ +1. Navigate to the _Spaces_ section +2. Select _Details_ on the target Space/Bucket +3. Select _Delete_ on the target object +4. The list of objects should reload without the deleted one +
