+### Redacting Text
+
+To redact PII in text:
+
+```bash
+datafog redact-text "Tim Cook is the CEO of Apple and is based out of Cupertino, California"
+```
+
+which should output:
+
+```bash
+[REDACTED] is the CEO of [REDACTED] and is based out of [REDACTED], [REDACTED]
+```
+
+### Replacing Text
+
+To replace detected PII:
+
+```bash
+datafog replace-text "Tim Cook is the CEO of Apple and is based out of Cupertino, California"
+```
+
+which should return something like:
+
+```bash
+[PERSON_B86CACE6] is the CEO of [UNKNOWN_445944D7] and is based out of [UNKNOWN_32BA5DCA], [UNKNOWN_B7DF4969]
+```
+
+Note: a unique randomly generated identifier is created for each detected entity
+
+### Hashing Text
+
+You can select from SHA256, SHA3-256, and MD5 hashing algorithms to hash detected PII. Currently the hashed output does not match the length of the original entity, for privacy-preserving purposes. The default is SHA256.
+
+```bash
+datafog hash-text "Tim Cook is the CEO of Apple and is based out of Cupertino, California"
+```
+
+generating an output which looks like this:
+
+```bash

+## Text Anonymization
+
+DataFog provides various anonymization techniques to protect sensitive information. Here are examples of how to use them:
+
+### Redacting Text
+
+To redact PII in text:
+
+```python
+from datafog import DataFog
+from datafog.config import OperationType
+
+client = DataFog(operations=[OperationType.SCAN, OperationType.REDACT])
+
+text = "Tim Cook is the CEO of Apple and is based out of Cupertino, California"
+redacted_text = client.run_text_pipeline_sync([text])[0]
+print(redacted_text)
+```
+
+Output:
+
+```
+[REDACTED] is the CEO of [REDACTED] and is based out of [REDACTED], [REDACTED]
+```
+
+### Replacing Text
+
+To replace detected PII with unique identifiers:
+
+```python
+from datafog import DataFog
+from datafog.config import OperationType
+
+client = DataFog(operations=[OperationType.SCAN, OperationType.REPLACE])
+
+text = "Tim Cook is the CEO of Apple and is based out of Cupertino, California"
+replaced_text = client.run_text_pipeline_sync([text])[0]
+print(replaced_text)
+```
+
+Output:
+
+```
+[PERSON_B86CACE6] is the CEO of [UNKNOWN_445944D7] and is based out of [UNKNOWN_32BA5DCA], [UNKNOWN_B7DF4969]
+```
+
+### Hashing Text
+
+To hash detected PII:
+
+```python
+from datafog import DataFog
+from datafog.config import OperationType
+from datafog.models.anonymizer import HashType
+
+client = DataFog(operations=[OperationType.SCAN, OperationType.HASH], hash_type=HashType.SHA256)
+
+text = "Tim Cook is the CEO of Apple and is based out of Cupertino, California"
+hashed_text = client.run_text_pipeline_sync([text])[0]
+print(hashed_text)
+```
+
+Output:
+
+```
+5738a37f0af81594b8a8fd677e31b5e2cabd6d7791c89b9f0a1c233bb563ae39 is the CEO of f223faa96f22916294922b171a2696d868fd1f9129302eb41a45b2a2ea2ebbfd and is based out of ab5f41f04096cf7cd314357c4be26993eeebc0c094ca668506020017c35b7a9c, cad0535decc38b248b40e7aef9a1cfd91ce386fa5c46f05ea622649e7faf18fb
+```
+
+You can choose from SHA256 (default), SHA3-256, and MD5 hashing algorithms by specifying the `hash_type` parameter
