+# Comtodon
+
+A minimal commenting system for static blogs using external [Mastodon](https://joinmastodon.org) or API [compatible](https://pleroma.social) server.
+
+- **painless:** use already existing fediverse accounts
+- **serverless:** hosted on static server or cdn
+- **lightweight:** any useless features *(IMO)*
+- **no dependencies:** pure native js
+- **personal:** no style, no tracking
+
+```html
+<div class="comtodon" data-domain="mastodon.social" data-status="100745593232538751"></div>
+<script src="comtodon.min.js" defer></script>
+```
+
+See [index.html](index.html)
+
+## Deep
+
+Create a tree by adding `data-deep=N`
+  - 0: Full tree
+  - 1: Only "direct" replies
+  - 2: With replies to replies
+  - And so on
+
+## Moderation ?
+
+Add `data-moderator="{moderator_id}"` to display only approved *(replied)* comments
+
+Note: Can't use fav, it requires authentication
+
+## Hugo
+Put `comtodon.min.js` in `static` folder
+
+In your site config
+```yaml
+params:
+  comtodon:
+    domain: mastodon.social
+    # moderator: 358957
+```
+
+In your single page layout
+```html
+{{ if .Params.comtodon }}
+<div class="comtodon" data-domain="{{ .Site.Params.comtodon.domain }}" data-status="{{ .Params.comtodon }}" {{ with .Site.Params.comtodon.moderator }}data-moderator="{{ . }}"{{ end }}></div>
+<script src="//comtodon.min.js" defer></script>
+{{- end }}
+```
+
+In your content header
+```yaml
+comtodon: 100745593232538751
+```
+
+**Style it**
+
+## Mastodon
+
+Only use `/api/v1/statuses/:id/context`. See [doc](https://docs.joinmastodon.org/api/rest/statuses/#get-api-v1-statuses-id-context)
+
+> No authentication required
+
+```
+{
+  descendants: [{
+    account: {
+      acct,
+      avatar_static,
+      display_name,
+      id,
+      emojis: [{shortcode, static_url}],
+      url
+    },
+    created_at,
+    content,
+    emojis: [{shortcode, static_url}],
+    id,
+    in_reply_to_id,
+    sensitive,
+    spoiler_text
+  }]
+}
+```
+
+## No js ?
+
+Simple placeholder
+```html
+<div class="comtodon" data-domain="mastodon.social" data-status="100745593232538751">
+    <p class="no-js sad">Enable JavaScript to see comments</p>
+</div>
+```
+
+## TODO
+
+- Use personal status as sample
+- Create proxy backend for cache and moderating with fav
+- Auto-magically create statuses from hugo ???
