+## Configuring Table of content
+
+### TOC Title text
+
+Use the `--title` option to specify a (Markdown-formatted) custom TOC title; e.g., `doctoc --title '**Contents**' .` From then on, you can simply run `doctoc <file>` and doctoc will keep the title you specified.
+
+Alternatively, to blank out the title, use the `--notitle` option. This will simply remove the title from the TOC.
+
+### Min. heading level
+
+Use the `--minlevel` option to limit TOC entries to headings only at or above the specified level; e.g., `doctoc --minlevel 2 .`
+
+By default,
+
+- the min level used is 1 if it is not set
+
+Note: Currently supported values are only 1 and 2.
+
+### Max. heading level
+
+Use the `--maxlevel` option to limit TOC entries to headings only up to the specified level; e.g., `doctoc --maxlevel 3 .`
+
+By default,
+
+- no limit is placed on Markdown-formatted headings,
+- whereas headings from embedded HTML are limited to 4 levels.
+
+### Include all Headings
+
+Use the `--all` option to include all headings in the TOC regardless of their location
+
+By default,
+
+- Only headings below the TOC will be included
+
