+# Newsletter {{ env.NEWSLETTER_COUNTER}}: {{ env.NEWSLETTER_MONTH }} {{ env.NEWSLETTER_YEAR }}
+
+###### tags: `newsletter`
+
+**Editors:**
+
+Another month has gone by, so it's time to put together the Rust Gamedev newsletter with {{ env.NEWSLETTER_MONTH }}'s news!
+
+## Current Schedule
+
+**The deadline for all section PRs is the 03.{{ env.NEWSLETTER_DEADLINE }}**
+
+We _may_ still accept PRs that are submitted later than this, as long as they're ready before the newsletter's release, but this isn't guaranteed. If you want your section to be included, don't leave it till the last minute!
+
+## Current Structure & Status
+
+Below is our current planned structure for the newsletter, and the status of each PR (which we'll try to keep updated).
+
+This is **not** an exhaustive list - if you have your own project that you want to write about, just make a comment on this issue and open a PR!

+## How to Contribute
+
+If you want to help writing the newsletter:
+
+    * **Read [CONTRIBUTING.md](https://github.com/rust-gamedev/rust-gamedev.github.io/blob/source/CONTRIBUTING.md?rgh-link-date=2023-09-12T16%3A17%3A34Z).**
+
+    * Choose one or more of the "🆓 **free**" sections listed below, and leave a comment letting us know you want to work on them.
+      
+      * The links in brackets (like "[1](#), [2](#), [3](#)") are suggestions of links to include in the section. Feel free to add more!
+      * The username listed next to the section (like "@ozkriff?") is a suggestion of who may want to pick up the work (usually the project's developer, or someone who has expressed interest in the past).
+      * You are not obligated to write a section if you're tagged or your project is listed! You're welcome to ask someone else to write the section, or to ask for your project to be excluded from this month's post.
+      * Extra sections not listed in the plan are welcomed - just leave a comment and open a PR!
+
+    * Write a short overview in the newsletter's Markdown file, making sure to follow the style guidelines (see below).
+
+    * Send a PR _to the `source` branch_ (example: [N15: A/B Street #336](https://github.com/rust-gamedev/rust-gamedev.github.io/pull/336)).
+
+    * Mention this issue in your PR's description to link it all together.
+
+## Style Guidelines
+
+The full style guide is in [CONTRIBUTING.md](https://github.com/rust-gamedev/rust-gamedev.github.io/blob/source/CONTRIBUTING.md?rgh-link-date=2023-09-12T16%3A17%3A34Z), but here are the most important rules:
+
+    * Write in third-person perspective.
+
+    * Each line must be 80 characters or less, for ease of reviewing/diffing.
+
+    * Only one image per section is allowed.
+      
+      * The maximum size is 300kb for static images and 2.5mb for GIFs.
+      * The image should come before the text, and must have alt text for accessibility.
+      * Prefer static images to GIFs, to keep the page load times down.
+
+    * Each section should be under 1000 characters, and under 6 paragraphs.
+      
+      * This only applies to the rendered text, not the markup.
+
+    * Keep formatting minimal - no bold/italics/etc.
+
+    * Avoid long/nested bullet point lists - no changelogs!
+
+Please use these templates as a starting point:
+
+**Games/apps/libraries:**
+
