-A simple and efficient Gemini-to-HTTP proxy written in Rust.
+September is a simple and efficient Gemini-to-HTTP proxy written in [Rust](https://www.rust-lang.org/).
+
+September remains simple, but packs more features than you could imagine, all configurable via environment variables.
 
 ## Usage
 
 A production deployment of September can be found at https://fuwn.me, with the root capsule set as [gemini://fuwn.me](gemini://fuwn.me).
 
-You can try proxying any external capsule through the /proxy route: e.g., https://fuwn.me/proxy/geminiprotocol.net/
+You can try proxying any external capsule through the `/proxy/` route: https://fuwn.me/proxy/geminiprotocol.net/.
 
 ### Docker
 
+`docker run` allows you to pass environment variables via the `-e` flag.
+
 ```shell
-docker run -d [ -e ROOT="gemini://fuwn.me" ] [ -e PORT="8080"] [ -e CSS_EXTERNAL="https://example.com/style.css"] fuwn/september:latest
+# September with a custom root, listening on port 8080
+docker run -d \
+  -e ROOT="gemini://fuwn.me" \
+  -p 8080:80 \
+  fuwn/september:latest
+
+# September with a custom root, port, and external stylesheet, listening on port 80
+docker run -d \
+  -e ROOT="gemini://fuwn.me" \
+  -e PORT="8080" \
+  -e CSS_EXTERNAL="https://example.com/style.css" \
+  -p 80:80 \
+  fuwn/september:latest
 ```
 
+You may start to find this way of passing configuration cumbersome for many options, so Docker management tool like [Portainer](https://www.portainer.io/) or a Docker Compose file might come in handy.
+
 ### Docker Compose
 
-Edit the `docker-compose.yaml` file to your liking, and then
+Docker Compose is a file-configurable Docker utility to make deploying exact container configuration and configuration sets simple. This repository provides a sample Docker Compose file, [`./docker-compose.yaml`](./docker-compose.yaml), with some examples configuration values that you can modify to your liking.
+
+After editing the file, you can bring up the composition using `docker-compose` command.
 
 ```shell
 docker-compose up -d
 ```
 
 ### Executable
 
+While generally discouraged, you can run the September executable by itself and configure it through environment variables.
+
 ```shell
-[ ROOT="gemini://fuwn.me" ] [ PORT="8080"] [ CSS_EXTERNAL="https://example.com/style.css"] ./september
+ROOT="gemini://fuwn.me" PORT="8080" CSS_EXTERNAL="https://example.com/style.css" ./september
 ```
 
-or use a `.env` file
+If available, September will use the relative directory's `.env` file for populating its configuration. Here is an example `.env` file with a few values added.
 
 ```dotenv
 # .env
 
 ROOT=gemini://fuwn.me
 PORT=8080
 CSS_EXTERNAL=https://example.com/style.css
-HEAD=<script>/* september */</script>
-```
-
-and then
-
-```shell
-./september
+HEAD=<script>/* This will appear in the head of the HTML document. */</script>
 ```
 
 ## Configuration
 
-All configuration options with examples can be found in the [Configuration.md](./Configuration.md) file.
+All configuration options with examples can be found in the [Configuration.md](./Configuration.md) file. Regardless of deployment method, these options remain present in each case.

-## Capsules using September
+## Origins
+
+The story of September starts with a simple request to add environment variable-configurable options to a pre-existing Gemini proxy.
+
+The proxy in question already had options, just that they were command-line flag configurable options. Apparently, containerising a networked application is not a "valid use-case", and everyone should prefer running raw binaries on their systems and servers. Also, finicky command-line arguments reign superior to the industry standard environment variable, or at least that's what I gather from this author's response to adding a few extra lines of code that I already wrote out for environment variable support.
 
-[Add yours!](https://github.com/gemrest/september/edit/main/README.md)
+Anyway, I forked the proxy. Somewhere down the line, I realised that this proxy just isn't cutting it and was poorly designed to begin with, so I threw it in the figurative trash, and wrote September from scratch.
 
-- <https://fuwn.me/>
-- <https://gem.rest/>
+In the end, it all worked out, since September has become the easiest to configure, most feature-packed, quickest to understand (and quickest in general) Gemini-to-HTTP proxy of the bunch.
