+A single `README.md` with compact Markdown tables — inspired by
+[terraform-docs](https://github.com/terraform-docs/terraform-docs).
+
+Supports **marker-based injection** into existing README files:
+
+```markdown
+# My Pipeline
+
+Some intro text.
+
+<!-- BEGIN_NF_DOCS -->
+<!-- END_NF_DOCS -->
+
+Other content below.
+```
+
+Running `nf-docs generate . -f table -o .` will inject the generated tables between the markers,
+leaving the rest of the file untouched.
+
+#### Selective sections with template tags
+
+Control which sections appear by adding `{{ section }}` placeholders between the markers:
+
+```markdown
+<!-- BEGIN_NF_DOCS -->
+{{ inputs }}
+
+{{ config }}
+<!-- END_NF_DOCS -->
+```
+
+Available tags: `{{ header }}`, `{{ inputs }}`, `{{ config }}`, `{{ workflows }}`,
+`{{ processes }}`, `{{ functions }}`.
+
+If no tags are present, all sections are rendered (the default).
