I have tried following the instructions on this link, https://docs.microsoft.com/en-us/powerapps/developer/common-data-service/publish-app-appsource but i am completely stuck. I am not sure what steps to follow while creating a managed solution. Should i use the steps written on that link or should i use the Solution tab under powerapps? 
On step 3.
Step 3: Create an AppSource package for your app
I have tried creating a package file as instructed, but i am not sure which files they are referring to here: Coz i only have one zipped file that was generated when i used the Solutions tab to create a managed solution inside powerapps. Should i add this one zipped file while creating a package or should i unzip it and add the individual files independently? I am completely stuck and i am not sure how i am supposed to proceed, coz the more i go further on this link; https://docs.microsoft.com/en-us/power-platform/alm/package-deployer-tool the more confusing it becomes for me. 
From, Step 3: Update the HTML files: English and other languages Step 4: Specify the configuration values for the package
All these steps are completely confusing for me. For instance under the Step. 4. What does install sample data to Common Data Service means? Does this apply to my case since i am using sharepoint list as my datasource?

Under the ImportConfig.xml file i see i am supposed to provide configurations for <zipimportdetails>, what exactly are these? I clearly don't have csv or txt files, i only have my one zip file.
In all honesty when i read through these instructions and try to implement them, they just don't seem to relate at all to powerapps or whatever i have as my zipped managed solution file that i generated under Solutions in powerapps. What am i missing? At this point i am completely lost and frustrated coz i can't seem to be able to publish my ready powerapps on appsource due to all these complications. I really wish there was a simple, straightforward guide specific to powerapps putting into considerations those of us who haven't used CDS, but other datasources like Sharepoint list. This is a simple canvas powerapp with sharepoint list data source.
