-# An Example Redis Module
+# Redis Module for maintaining hash by simple SQL
 
-This project is a simple redis module demonstrating basic API usage and `librmutil`. 
+## Example
+```bash
+$ redis-cli
+127.0.0.1:6379> hmset phonebook:0001 name "Peter Nelson"     tel "1-456-1246-3421" country "US" effective "2019-10-01" pos 3 flag "Y"
+127.0.0.1:6379> hmset phonebook:0002 name "Boris John"       tel "1-444-9999-1112" country "UK" effective "2019-12-01" pos 1 flag "N"

+## Getting started
+
+### Get the package and build the binary:
+```bash
+git clone https://github.com/cscan/dbx.git
+cd dbx/src && make
+```
+
+This plugin library is written in pure C. A file dbx.so is built after successfully compiled.
+
+### Load the module in redis
+```bash
+127.0.0.1:6379> module load /path/to/dbx.so
+```
+OR
+Start the server with loadmodule argument
+```bash
+$ redis-server --loadmodule /path/to/dbx.so
+```
+OR
+Adding the following line in the file redis.conf and then restart the server
+```bash
+loadmodule /path/to/dbx.so
+```
+
