+# PDF Text Search and Replace
+
+This example shows how to do text search and replacement on PDF using unipdf.
+
+## Examples
+- [search_text.go](search_text.go) This examples shows how to do text searching using unipdf's by providing the pattern string and the pages to search on.
+- [replace_text.go](replace_text.go) This example show how to replace a given text by searching for it using a pattern and a replacement string. 
+A list of pages is also provided in the parameter to specify which to do the replacement.
\ No newline at end of file
