+I want marker to be as widely accessible as possible, while still funding my development/training costs.  Research and personal usage is always okay, but there are some restrictions on commercial usage.

 PDF is a tricky format, so marker will not always work perfectly.  Here are some known limitations that are on the roadmap to address:
 
 - Marker will not convert 100% of equations to LaTeX.  This is because it has to detect then convert.
+- Tables are not always formatted 100% correctly - text can be in the wrong column.
 - Whitespace and indentations are not always respected.
 - Not all lines/spans will be joined properly.
 - This works best on digital PDFs that won't require a lot of OCR.  It's optimized for speed, and limited OCR is used to fix errors.
 
 # Installation
 
-This has been tested on Mac and Linux (Ubuntu and Debian).  You'll need python 3.9+ and PyTorch.  You may need to install the CPU version of torch first if you're not using a Mac or a GPU machine.  See [here](https://pytorch.org/get-started/locally/) for more details.

+There are some settings that you may find useful if things aren't working the way you expect:
 
 - `OCR_ALL_PAGES` - set this to true to force OCR all pages.  This can be very useful if the table layouts aren't recognized properly by default, or if there is garbled text.
 - `TORCH_DEVICE` - set this to force marker to use a given torch device for inference.
 - `OCR_ENGINE` - can set this to `surya` or `ocrmypdf`.
 - `DEBUG` - setting this to `True` shows ray logs when converting multiple pdfs
+- Verify that you set the languages correctly, or passed in a metadata file.
+- If you're getting out of memory errors, decrease worker count (increased the `VRAM_PER_TASK` setting).  You can also try splitting up long PDFs into multiple files.
