+Redprine
+========
+
+Automatically update Redmine issues based on open pull requests.
+
+After opening a pull request, you might need to update the corresponding Redmine
+ticket with new status information. This program does that work automatically.
+
+The script should be run through a service manager like `cron` or `launchd`. At
+each run, it will fetch all open pull requests for the given project, and update
+the corresponding Redmine issue of each new pull request.
+
+
+## Usage
+Several parameters are required to configure the script to enable it to
+communicate with both GitHub and Redmine.
+
+Both a [GitHub personal access token][1] and Redmine API key
+(`https://redmine.example.com/my/account`) are needed.
+
+Here’s an example script with all required arguments:
+
+	#!/bin/sh
+
+	redprine \
+		--github-token 'GITHUB_TOKEN' \
+		--github-username 'teddywing' \
+		--github-owner-repo 'teddywing/redprine' \
+		--redmine-base-url 'https://redmine.eaglejump.co' \
+		--redmine-token 'REDMINE_TOKEN' \
+		--redmine-json-params 'echo "
+			{
+				\"issue\": {
+					\"status_id\": 4,
+					\"done_ratio\": 100,
+					\"custom_field_values\": {
+						\"1\": \"$0\"
+					}
+				}
+			}
+		"'
+
+In `--redmine-json-params`, enter a string containing a Bash command (it will be
+executed with `bash -c`). A single argument is passed in `$0` containing the URL
+of the issue’s pull request. The format must match Redmine’s JSON parameter for
+the [issue update API endpoint][3].
+
+
+## Install
+Requirements:
+
+* `curl`
+* [`jq`][2]
+
+Download and copy the [Redprine script][4] into your `PATH`.
