+## Configure Credentials for Authentication
+
+### Method 1: Using hasher_generate
+
+1 - Update the Environment
+
+    Ensure that you have the latest version of the project and reinstall the conda environment if needed.
+
+2 - Generate Hashed Password
+
+    Open a Python terminal and utilize hasher_generate from Streamlit to generate a hashed password. Example code:
+
+    ```
+    import streamlit_authenticator as st_auth
+    hashed_password = st_auth.hasher_generate("YOUR_PLAIN_TEXT_PASSWORD")
+
+    ```
+
+3 - Edit the Credentials YAML File
+
+    Locate the credentials YAML file in the root directory.
+    Edit the file by inserting the generated hashed password from Step 2.
+
+4 - Accessing the Dashboard
+
+    Run the Hummingbot Dashboard project.
+    Use the username and the plain text password (used in Step 2) to log in to the dashboard.
+
+5 - Logging Out
+
+    To log out, navigate to the dashboard and select 'Logout'.
+
+
+### Method 2: Using Pre-Authorized Emails for User Registration
+
+1 - Update the Environment
+
+    As in Method 1, ensure your conda environment and project version are up-to-date.
+
+2 - Whitelist Emails
+
+    In the credentials YAML file, add the emails of users who will be pre-authorized to register and create their credentials.
+
+    ```
+    pre_authorized_emails:
+      - [email protected]
+      - [email protected]
+    ```
+
+3 - User Registration
+
+    Direct users to the Hummingbot Dashboard.
+    Users should select 'Register' and enter one of the pre-authorized email addresses.
+    They will choose their own username and password during registration.
+
+4 - First-Time Login
+
+    Users log in with their chosen username and password.
+    The dashboard will hash and store their credentials automatically.
+
+5 - Logging Out
+
+    Similar to Method 1, users can log out by navigating to the dashboard and selecting 'Logout'.
