+# HTTP File Server
+
+This actor (we like to call it "Little Blobby Tables") is a simple file server showing the basic
+CRUD operations of the `wasmcloud:blobstore` contract.
+
+Not only is this actor an example, it is also a fully-functional, HTTP-based fileserver that can be
+fronted with any HTTP server implementation and any blobstore implementation (i.e. you could store
+the uploaded files on a filesystem or in an s3 compatible store). It also has a full example of
+integration testing for the actor
+
+## Required Capability Claims
+
+1. `wasmcloud:httpserver` to receive http requests
+2. `wasmcloud:blobstore` to save the image to a blob
+3. `wasmcloud:builtin:logging` so the actor can log
+
+## Running this example
+
+Click on the button below to launch the XKCD Generator on Cosmonic Now:
+
+[![Deploy on Cosmonic](https://cosmonic.com/badge/deploy.svg)](https://new.cosmonic.app/?yaml=https://raw.githubusercontent.com/cosmonic/awesome-cosmonic/http-file-server/http-file-server.wadm.yaml)
+
+Once everything is up and running, you can run through all of the operations by following the
+annotated commands below:
+
+```bash
+export MY_WORMHOLE="your-wormhole-goes-here.cosmonic.app"
+
+# to upload a file
+export MESSAGE="Hello there\!"
+curl -w "%{http_code}" -H 'Content-Type: text/plain' "https://$MY_WORMHOLE.cosmonic.app/myfile.txt" -d "$MESSAGE"
+
+# to download a file
+curl "https://$MY_WORMHOLE.cosmonic.app/myfile.txt"
+
+# to edit a file, post again
+export MESSAGE="$MESSAGE General Kenobi\!"
+curl -w "%{http_code}" -H 'Content-Type: text/plain' "https://$MY_WORMHOLE.cosmonic.app/myfile.txt" -d "$MESSAGE"
+
+# download the file again
+curl "https://$MY_WORMHOLE.cosmonic.app/myfile.txt"
+```
