+# To use pgindent, set the PATH environment variable to include the directories
+# containing the binaries pgindent and pg_bsd_indent. It is important to
+# utilize a specific version of pg_bsd_indent, which sources can be found
+# in the <postgresql>/src/tools/pg_bsd_indent directory, where <postgresql>
+# is the root directory of the PostgreSQL project source tree.
+#
+# The sources of the utilities can be found in the following directories:
+# - <postgresql>/src/tools/pgindent
+# - <postgresql>/src/tools/pg_bsd_indent
+#
+# pgindent-typedefs.list should be updated every time after implementing
+# new types and introducing new typedefs in the code. For details how
+# to update pgindent-typedefs.list and for other information about pgindent,
+# please, read the doc: <postgresql>/src/tools/pgindent/README.
+#
+# pgindent-excludes.list is used to specify files to be ignored.
