+# Publish Markdown articles to Nostr
+
+I'm currently using [this bash script][1] to publish [long-form content][2]
+from local Markdown files to Nostr relays.
+
+It requires all of `yq`, `jq`, and `nak` to be installed.
+
+## Usage
+
+Create a signed Nostr event and print it to the console:
+
+    markdown_to_nostr.sh article-filename.md
+
+Create a Nostr event and publish it to one or more relays:
+
+    markdown_to_nostr.sh article-filename.md ws://localhost:7777 wss://nostr.kosmos.org
+
+## Markdown format
+
+You can specify your metadata as YAML in a Front Matter header. Here's an
+example file:
+
+```md
+---
+title: "Good Morning"
+summary: "It's a beautiful day"
+image: https://example.com/i/beautiful-day.jpg
+date: 2025-04-24T15:00:00Z
+tags: gm, poetry
+published: false
+---
+
+In the blue sky just a few specks of gray  
+In the evening of a beautiful day  
+Though last night it rained and more rain on the way  
+And that more rain is needed 'twould be fair to say.
+
+— Francis Duggan
+```
+
+The metadata keys are mostly self-explanatory. Note:
+
+* All keys except for `title` are optional
+* `date`, if present, will be set as the `published_at` date.
+* If `published` is set to `true`, it will publish a kind 30023 event,
+  otherwise a kind 30024 (draft)
