+# Dataprep Microservice with Elasticsearch
+
+## 🚀1. Start Microservice with Python（Option 1）
+
+### 1.1 Install Requirements
+
+```bash
+pip install -r requirements.txt
+```
+
+### 1.2 Setup Environment Variables
+
+```bash
+export ES_CONNECTION_STRING=http://localhost:9200
+export INDEX_NAME=${your_index_name}
+```
+
+### 1.3 Start Elasticsearch
+
+Please refer to this [readme](../../../vectorstores/elasticsearch/README.md).
+
+### 1.4 Start Document Preparation Microservice for Elasticsearch with Python Script
+
+Start document preparation microservice for Elasticsearch with below command.
+
+```bash
+python prepare_doc_elastic.py
+```
+
+## 🚀2. Start Microservice with Docker (Option 2)
+
+### 2.1 Start Elasticsearch
+
+Please refer to this [readme](../../../vectorstores/elasticsearch/README.md).
+
+### 2.2 Setup Environment Variables
+
+```bash
+export ES_CONNECTION_STRING=http://localhost:9200
+export INDEX_NAME=${your_index_name}
+```
+
+### 2.3 Build Docker Image
+
+```bash
+cd GenAIComps
+docker build -t opea/dataprep-elasticsearch:latest --build-arg https_proxy=$https_proxy --build-arg http_proxy=$http_proxy -f comps/dataprep/elasticsearch/langchain/Dockerfile .
+```
+
+### 2.4 Run Docker with CLI (Option A)
+
+```bash
+docker run  --name="dataprep-elasticsearch" -p 6011:6011 --ipc=host -e http_proxy=$http_proxy -e https_proxy=$https_proxy -e ES_CONNECTION_STRING=$ES_CONNECTION_STRING  -e INDEX_NAME=$INDEX_NAME -e TEI_ENDPOINT=$TEI_ENDPOINT opea/dataprep-elastic:latest
+```
+
+### 2.5 Run with Docker Compose (Option B)
+
+```bash
+cd comps/dataprep/elasticsearch/langchain
+docker compose -f docker-compose-dataprep-elastic.yaml up -d
+```
+
+## 🚀3. Consume Microservice
+
+### 3.1 Consume Upload API
+
+Once document preparation microservice for Elasticsearch is started, user can use below command to invoke the
+microservice to convert the document to embedding and save to the database.
+
+```bash
+curl -X POST \
+    -H "Content-Type: application/json" \
+    -d '{"path":"/path/to/document"}' \
+    http://localhost:6011/v1/dataprep
+```
+
+### 3.2 Consume get_file API
+
+To get uploaded file structures, use the following command:
+
+```bash
+curl -X POST \
+    -H "Content-Type: application/json" \
+    http://localhost:6011/v1/dataprep/get_file
+```
+
+Then you will get the response JSON like this:
+
+```json
+[
+  {
+    "name": "uploaded_file_1.txt",
+    "id": "uploaded_file_1.txt",
+    "type": "File",
+    "parent": ""
+  },
+  {
+    "name": "uploaded_file_2.txt",
+    "id": "uploaded_file_2.txt",
+    "type": "File",
+    "parent": ""
+  }
+]
+```
+
+### 4.3 Consume delete_file API
+
+To delete uploaded file/link, use the following command.
+
+The `file_path` here should be the `id` get from `/v1/dataprep/get_file` API.
+
+```bash
+# delete link
+curl -X POST \
+    -H "Content-Type: application/json" \
+    -d '{"file_path": "https://www.ces.tech/.txt"}' \
+    http://localhost:6011/v1/dataprep/delete_file
+
+# delete file
+curl -X POST \
+    -H "Content-Type: application/json" \
+    -d '{"file_path": "uploaded_file_1.txt"}' \
+    http://localhost:6011/v1/dataprep/delete_file
+
+# delete all files and links
+curl -X POST \
+    -H "Content-Type: application/json" \
+    -d '{"file_path": "all"}' \
+    http://localhost:6011/v1/dataprep/delete_file
+```
