 Note that at the moment the ssh adapter does not support Windows machines, and it requires the server to have a `/bin/sh` binary as well as standard unix commands (`ls`, `rm`, `mv`, `mkdir`, `chmod`, `cp`, `touch`, `ln`, `echo`).
 
+### S3
+
+This adapter allows you to browse files stored in aws s3. To use it, make sure `aws` is setup correctly and then simply open a buffer using the following name template:
+
+```
+nvim oil-s3://[bucket]/[path]
+```
+
+Note that older versions of Neovim don't support numbers in the url, so for Neovim 0.11 and older the url starts with `oil-sss`.

 - [defx.nvim](https://github.com/Shougo/defx.nvim): What I switched to after vim-vinegar. Much more flexible and performant, but requires python and the API is a little hard to work with.
 - [dirbuf.nvim](https://github.com/elihunter173/dirbuf.nvim): The first plugin I encountered that let you edit the filesystem like a buffer. Never used it because it [can't do cross-directory edits](https://github.com/elihunter173/dirbuf.nvim/issues/7).
