 # Fling
-Have you ever missed the simplicity of an USB Stick when sharing data over the
-net?
-
-Zero-friction sharing is a surprisingly unsolved problem. There's no reasonably
-ubiquitous solution installed on everybody's machine. Online providers are often
-packed with features, but miss out on things like direct download urls, a space
-for others to easily _upload_ to you, or require registration from all
-participants. I don't remember any of these things being a problem with USB 🤔.
-
 Fling is a self-hosted file share. It is simple like USB without missing out on
-the good parts of the web:
-- Drop files on a fling and share the URL. That's it. The fling way of life.
-
-Other features include:
-- Choose your own, meaningful name for your sharing URL
+the good parts of a web app:
+- Just drop files on a Fling and share the URL
+- Choose your own name for your share-URL
 - Share a direct download link
-- Choose to let others upload files just as simple
+- Let others upload files
 - Protect your fling by a password - no registration required
-- Let a fling expire after a date or a number of clicks (or keep it forever)
+- Let a fling expire after a date or a number of clicks
 
-# Fling is a API
-It gets even better!
+# API
+Fling is distributed as both, a backend service and a web interface. You can use
+the backend on its own with any [HTTP client](examples).
 
-Fling is a backend service and a web interface. But you can use anything else
-that speaks HTTP if you prefer. In fact, we generate and publish a javascript
-and python client for the Fling API on every build. If you like it bare-bones
-there is also a querysheet in the examples folder with raw HTTP calls.
+Per default Fling publishes a Swagger UI page and an OpenAPI spec. You can find
+them here:
 
-Fling also has a code-first OpenAPI compliant spec. O mon Dieu, it just checks
-_all_ the boxes!
+``` http
+http://<host>:<port>/swagger-ui.html
+http://<host>:<port>/v3/api-docs
+```
 
-# Fling as a container
-It gets even even better better!
+If starting the fling container locally, the default `<host>:<port>` is
+http://localhost:3000. You can also find a recent version of it via
+https://fling.friedl.net/swagger-ui.html and
+https://fling.friedl.net/v3/api-docs.
 
-Fling is self-hosted. But it is packaged up in a container for easy deployment.
-Run `docker run --rm -p3000:3000 arminfriedl/fling` and go to
-http://localhost:3000. The default admin user is `adminName:adminPassword`.
+# Starting Fling from Docker
+A Fling container is provided at https://hub.docker.com/repository/docker/arminfriedl/fling. 
+
+1. Run `docker run --rm -p3000:3000 arminfriedl/fling` 
+2. Go to the default http://localhost:3000
+3. Log in with `adminName:adminPassword`.
 
 ## Configuring Fling
 The Fling container can be configured by environment variables.
 
-Web interface configuration (`config.js`/`config.js.template`; will be replaced
-by `envsubst` when the container starts up):
-
+The web interface configuration ([config.js](web/fling/public/config.js)/[config.js.template](container/var/www/fling/config.js.template)) will be
+filled by `envsubst` when the container starts up.
 ``` sh
 # The base URL of the Fling API service
 FLING_API_BASE=http://localhost:3000
+# Log level of the application
 FLING_LOG_LEVEL=warn
-# Max. upload size in bytes
+# Max. upload size in bytes. Checked on client side.
 FLING_FILESIZE=209715200
