+# HCRA Server
+
+This is the server for HamClock Remote Access. It is a Python web app written
+using Tornado.
+
+On its own, the server is useless; it requires HamClock, available at
+http://clearskyinstitute.com/ham/HamClock/ (installed on the same machine as
+the HCRA server), and the HCRA client (see `../client`).
+
+## Installation
+
+The server itself does not need to be installed; it is simply run with
+`python3 wss.py` in this directory. However, it does have some dependencies
+(both Python packages and binaries).
+
+### Python packages
+
+    pip3 install -r requirements.txt
+
+### Binaries
+
+#### Ubuntu, Mint, possibly Debian, etc.
+
+    sudo apt install $(cat ubuntu-pkgs.txt)
+
+#### Other distros
+
+Unfortunately, I only have Mint computers, so I can't help with other
+distros.
+
+You will need the following:
+
+* ImageMagick 6
+* X11 development headers
+* `Xvfb`
+* `xdotool`
+* `xwd`
+
+## Backends
+
+The server can connect to HamClock in one of two ways; it can either use
+HamClock's built-in port 8080 service, or it can use X11. The X11 method is
+highly recommended when it can be used, because it does not occasionally
+freeze when HamClock is on certain screens like the port 8080 backend does.
+
+## `conf.txt`
+
+The server will not work without a `conf.txt` file. This file is a
+space-separated table of configuration data. See the included file for a
+reference. (That file will work for testing, but should not be used on an
+Internet-accessible server. The password is `Testing123`. It uses the X11
+backend, `DISPLAY=:1`.)
+
+### `backend`
+
+Use `x11` for the X11 backend, or `port8080` for the port 8080 backend.
+
+### `display`
+
+X11 display to use, such as `:1`. Has no effect with the `port8080` backend.
+
+### `password_argon2`
+
+Argon2-hashed password. Use `pwhash.py` to generate a hashed password.
