-webxdc apps can not access the Internet.
-That's what makes them private.
-So if you share the store app to another chat,
-it will not work there.
-Only because
-[xstore@testrun.org](mailto:xstore@testrun.org)
-is a chat bot which gets told by the store app
-which app you want to download,
-it can download the app from the Internet
-and send it to you in the chat.
-
-If you deleted the store or
-chose "clear chat" to clean up,
-you can at any point in time just send "hi"
-to [xstore@testrun.org](mailto:xstore@testrun.org) again,
-and it will re-send the store to the chat.

-## Do I have to use the official xstore?
-
-Of course not.
-You can always share a webxdc app from one chat to another;
-without DRM,
-without tracking,
-without login/consent barriers.
-Any webxdc app is just a .xdc file
-saved as an e-mail attachment.
-
-Additionally to that,
-you can also self-host the bot
-we use to offer xstore.
-You can find installation instructions
-[in the bot's codeberg repository](https://codeberg.org/webxdc/store/#setting-up-the-bot).

+## How does xstore work? Where does it get its apps from? 
+
+[xstore@testrun.org](mailto:xstore@testrun.org) is a chat bot instance.
+After you send “Hi” to the bot,
+you receive and start the store app,
+which continues to communicate with the bot
+for selecting and downloading apps.
+You can not share the store app
+to another chat.
+That’s because
+webxdc apps can not access the Internet,
+only the bot.
+
+If it was a website,
+you could say
+the store app is the frontend,
+the store bot is the backend.
+
+The xstore chat bot
+collects webxdc apps from a list of “git” repository sources
+and will continously offer the latest released app versions.
+You can also self-host the store bot:
+checkout installation instructions
+in the [bot’s codeberg repository](https://codeberg.org/webxdc/store/).
+It works well together with [xdcget](https://codeberg.org/webxdc/xdcget/),
+a command line tool
+which downloads webxdc releases
+from git public repositories.
