 As a technical writer at Postgres Professional, I created documentation for several PostgreSQL-based products,
 which included both enhanced flavors of vanilla PostgreSQL and various extensions or utilities.
-The sections below provide several samples of this work.
+This section lists some examples of this work:
 
-### Reference
-
-[pg_integrity_check utility](docs/pg_integrity_check.pdf)
-
-### Task
-
-This instruction was created as part of the Installation guide for Postgres Pro Standard.
-
-[Configuring multiple Postgres Pro instances on Windows](docs/postgres_install_win.md)
-
-### Concept
-
-This is a description of the jsonpath data type introduced in PostgreSQL for querying JSON data.
-The original patch submitted to PostgreSQL is available in the
-[official PostgreSQL repository](https://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=72b6460336e86ad5cafd3426af6013c7d8457367).

 ## Intel documentation
 
-The projects that I supported at Intel Corporation were quite diverse, but mostly
