 ## Example outputs
 The following documents are generated by [tests/test_rendering_example_doc.py](tests/test_rendering_example_doc.py):
 
 - HTML: [test_html_render.html](https://html-preview.github.io/?url=https://github.com/Nonannet/pyladoc/blob/main/tests/out/test_html_render.html)
-- PDF: [test_latex_render.pdf](https://raw.githubusercontent.com/Nonannet/pyladoc/refs/heads/main/tests/out/test_latex_render.pdf)
+- PDF: [test_latex_render.pdf](https://raw.githubusercontent.com/Nonannet/pyladoc/refs/heads/main/tests/out/test_LaTeX_render.pdf)
 
 ### Sported primitives
 - Text (can be Markdown or HTML formatted)
 - Headings
 - Tables (Pandas, Markdown or HTML)

-- LaTex equations
+- LaTeX equations
 - Named references for figures, tables and equation
 
 ### Key Features
-- HTML and PDF/LaTex rendering of the same document
+- HTML and PDF/LaTeX rendering of the same document
 - Single file output including figures
 - Figure and equation embedding in HTML by inline SVG, SVG in Base64 or PNG in Base64
-- Figure embedding in LaTex as PGF/TikZ
+- Figure embedding in LaTeX as PGF/TikZ
