 ## Features
 
-### Advanced Queries
+### Querying
 
-### Export
+`hishtory query` is the main interface for searching through your shell history. See some below annotated queries:
+
+| Command | Explanation |
+|---|---|
+| `hishtory query psql` | Find all commands containing `psql` |
+| `hishtory query psql db.example.com` | Find all commands containing `psql` and `db.example.com` |
+| `hishtory query docker hostname:my-server` | Find all commands containing `docker` that were run on the computer with hostname `my-server` |
+| `hishtory query nano user:root` | Find all commands containing `nano` that were run as `root` |
+| `hishtory query exit_code:127` | Find all commands that exited with code `127` |
+| `hishtory query service before:2022-02-01` | Find all commands containing `service` run before February 1st 2022 |
+| `hishtory query service after:2022-02-01` | Find all commands containing `service` run after February 1st 2022 |
+
+For true power users, you can query via SQL via `sqlite3 ~/.hishtory/.hishtory.db`. 
+
+In addition, `hishtory export` dumps all commands to stdout separated by a single line. This can be useful for certain advanced use cases. 
 
 ### Enable/Disable
 
-### update

+
