+# gp_url_tools: Cloudberry extension providing functionality for working with URL addresses
+
+### Features
+`gp_url_tools` is an extension for the Cloudberry database that gives implementation
+for functions that encode/decode url/uri.
+
+### Functions
+The extension creates the `url_tools_schema` schema and adds four SQL functions:
+
+- `url_tools_schema.encode_url`/`.encode_uri`  
+  Encodes a text value for use as a URL/URI component by replacing reserved characters with percent-encoded sequences.
+
+- `url_tools_schema.decode_url`/`.decode_uri`  
+  Decodes percent-encoded sequences in a URL/URI-encoded text value back to their original characters (human-readable).
+
+### Usage
+```sql
+CREATE EXTENSION gp_url_tools;
+```
+```sql
+SELECT url_tools_schema.encode_url('Hello World');
+```
+```bash
+  encode_url
+───────────────
+ Hello%20World
+(1 row)
+```
+```sql
+SELECT url_tools_schema.decode_url('Hello%20World');
+```
+```bash
+ decode_url  
+─────────────
+ Hello World
+(1 row)
+```
+```sql
+SELECT url_tools_schema.encode_uri('https://ru.wikipedia.org/wiki/Greenplum_(компания)');
+```
+```bash
+                                         encode_uri                  
+────────────────────────────────────────────────────────────────────────────────────────────
+ https://ru.wikipedia.org/wiki/Greenplum_(%D0%BA%D0%BE%D0%BC%D0%BF%D0%B0%D0%BD%D0%B8%D1%8F)
+```
+```sql
+SELECT url_tools_schema.decode_uri('https://ru.wikipedia.org/wiki/Greenplum_(%D0%BA%D0%BE%D0%BC%D0%BF%D0%B0%D0%BD%D0%B8%D1%8F)');
+```
+```bash
+                     decode_uri               
+────────────────────────────────────────────────────
+ https://ru.wikipedia.org/wiki/Greenplum_(компания)
+```
+
+### Acknowledgments
+Thank you very much for the extension for PostgreSQL: https://github.com/okbob/url_encode, its sources were very useful.
