# Zep Memory
[Zep](https://github.com/getzep/zep) is long-term memory store for LLM applications. It stores, summarizes, embeds, indexes, and enriches LLM app / chatbot histories, and exposes them via simple, low-latency APIs.
## Guide to Deploy Zep to Render
You can easily deploy Zep to cloud services like [Render](https://render.com/), [Flyio](https://fly.io/). If you prefer to test it locally, you can also spin up a docker container by following their [quick guide](https://github.com/getzep/zep#quick-start).
In this example, we are going to deploy to Render.
1. Head over to [Zep Repo](https://github.com/getzep/zep#quick-start) and click **Deploy to Render**
2. This will bring you to Render's Blueprint page and simply click **Create New Resources**
3. When the deployment is done, you should see 3 applications created on your dashboard
4. Simply click the first one called **zep** and copy the deployed URL
## Guide to Deploy Zep to Digital Ocean (via Docker)
1. Clone the Repo
```bash
git clone https://github.com/getzep/zep.git
cd zep
nano .env
```
2. Add IN your OpenAI API Key in.ENV
```bash
ZEP_OPENAI_API_KEY=
```
```bash
docker compose up -d --build
```
3. Allow firewall access to port 8000
```bash
sudo ufw allow from any to any port 8000 proto tcp
ufw status numbered
```
If using Digital ocean separate firewall from dashboard, make sure port 8000 is added there too
## Use in Flowise UI
1. Back to Flowise application, simply create a new canvas or use one of the template from marketplace. In this example, we are going to use **Simple Conversational Chain**
2. Replace **Buffer Memory** with **Zep Memory**. Then replace the **Base URL** with the Zep URL you have copied above
3. Save the chatflow and test it out to see if conversations are remembered.
4. Now try clearing the chat history, you should see that it is now unable to remember the previous conversations.
## Zep Authentication
Zep allows you to secure your instance using JWT authentication. We'll be using the `zepcli` command line utility [here](https://github.com/getzep/zepcli/releases).
#### 1. Generate a secret and the JWT token
After downloaded the ZepCLI:
On Linux or MacOS
```
./zepcli -i
```
On Windows
```
zepcli.exe -i
```
You will first get your SECRET Token:
Then you will get JWT Token:
#### 2. Configure Auth environment variables
Set the following environment variables in your Zep server environment:
```
ZEP_AUTH_REQUIRED=true
ZEP_AUTH_SECRET=
```
#### 3. Configure Credential on Flowise
Add a new credential for Zep, and put in the JWT Token in the API Key field:
#### 4. Use the created credential on Zep node
In the Zep node Connect Credential, select the credential you have just created. And that's it!
