How to follow Arrenite
You do not need an account, an email list or an app from us. A feed reader quietly checks for new letters and brings them to you in one place. Setting it up takes about two minutes.
What is a feed?
A feed is a plain list of a website's newest writing, in a form that reader apps understand. You give the reader the address once. After that, new letters simply appear, the way mail arrives, except that only what you chose can arrive, and nobody else sees what you read.
The usual name is RSS. It is the oldest way to follow the web without an algorithm deciding what you see, and it still works everywhere.
Follow in three steps
- Choose a reader. Any one will do. A few are suggested below.
- Copy the feed address for your language. In the reader, look for Add feed, Subscribe or a plus sign, and paste the address.
- Read. New letters arrive in full, with the diagrams and the word definitions.
Feed addresses
Each letter is published in English, Spanish and Filipino. Follow the language you read, or all three.

One file for all three languages
An OPML file is a list of feeds that most readers can import in one step. Download it, then choose Import in your reader.
If it does not work
- Paste the feed address (it ends in feed.xml or feed.json), not the page address.
- If your reader asks for a website instead, try arrenite.com/letters/ and it will find the feed for you.
- Some readers take a few minutes to fetch the first letters.
- Still stuck? Write to [email protected] and we will help.
Why there is no email list
We do not collect addresses, so there is nothing to leak, sell or unsubscribe from. A feed reader gives you the same convenience and keeps your reading private. If you prefer your inbox, some readers and tools can forward feed items to your email, and we never see your address.
For AI tools and developers
Everything here is also meant to be read by programs. These are plain files, with no sign-up and no keys.
- OPML, all three languages
- /follow.opml
- llms.txt
- /llms.txt, a map of the letters and glossary for language models
- Markdown copies
- Each letter, and this page, has a plain Markdown copy at the same address ending in .md, for example /follow.md
- Glossary as Markdown
- /glossary.md
- Sitemap
- /sitemap.xml, with the language alternates for every page
- Structured data
- Every page carries schema.org JSON-LD: articles, defined terms and breadcrumbs.
Please be kind to the server: check feeds no more than once an hour. Letters are written with AI assistance and say so; the feeds carry that note too.
