LaTex - Increase Section Depth - \subsubsubsection = \paragraph

Sometimes we need to go down to level 4, especially when using the Article class. At these times, it becomes necessary to find ways for typesetting sections at lower depth. To do that we use:

\paragraph{.}

To use sections (paragraphs), depth 4 and beyond, the following has worked for me:

• \usepackage{titlesec}

• \usepackage{titletoc}

• \setcounter{secnumdepth}{5}

• \setcounter{tocdepth}{5}

• \titleformat{\paragraph} [hang] {\normalfont\normalsize\bfseries} {\theparagraph} {1em} {}

Then use \paragraph{.} instead of \subsubsubsection{.} to create sections at depth 4. 

\setcounter{tocdepth}{5} instructs the compiler to add entries into the TOC upto depth 5.
