 # etcd_fdw
+
 A foreign data wrapper around etcd for postgres
 
 ## Setup
+
 - Install pgrx on your machine `cargo install --locked cargo-pgrx --version 0.16.1`
 - Setup pgrx `cargo pgrx init`
 - Install protoc and protobuf (needed by etcd-client)
-  - Instructions can be found [here](https://protobuf.dev/installation/)
+  - Instructions can be found [on the official site](https://protobuf.dev/installation/)
 - Have some kind of etcd you want to test and run
 
-
 ## Build
+
 - To build simply run `cargo pgrx run` with or without the `--release` flag
 
 ## Try out something yourself

 Currently we can only read from etcd.
 Here's an example of how to connect to your etcd instance and read some KVs

 ## Pushdowning

+### ORDER BY push-down

 `etcd_fdw` now also supports order by push-down. If possible, push order by
 clause to the remote server so that we get the ordered result set from the
 foreign server itself.
 
-#### LIMIT push-down

+perform LIMIT operations on the remote server.
 
 #### WHERE push-down
+
 `etcd_fdw` now supports WHERE clause push-down for simple key-based comparisons. Whenever possible, equality and range conditions are translated into etcd key scans, so filtering is done on the remote server.
 Currently supported operators: `=`, `>=`, `>`, `<=`, `<`, `BETWEEN`, and `LIKE 'prefix%'`.
 This behavior is consistent with the prefix, range_end, and key options in `CREATE FOREIGN TABLE`.

 ## What doesn't work
+
 etcd_fdw supports almost all kinds of CRUD operations. What doesn't work is modifying the key (which is the rowid value) directly using `UPDATE` statements.
 What does work is the following workflow:
