Simply add a file with "readme" (case doesn't matter) in the name into the folder you wish to document, using either the web UI or our FTP/SCP/rsync support.
We currently support any files with “README” in the name (case doesn't matter) that end in the following extensions:
Any other text README files are displayed as plain text, just like a README.txt file. Binary (PDF, Word documents) and HTML files are not displayed, though a link to download them is provided.
Raw HTML is not supported, even in the formats (e.g., Markdown) that allow its use. Any raw HTML will be escaped.
If a subfolder doesn't have its own README file, it will inherit the closest README in its parent folders.
When multiple READMEs are in the same folder, the newest file will be displayed.
