+## Pre-Workshop Checklist
+
+Before attending the workshop, please ensure that you have the required prerequisites installed and configured properly. Follow the steps below to verify your setup.
+
+### Repository Update
+
+Make sure that you have cloned the repo. You can see instructions on how to do so on the [Getting Started](../README.md#getting-started) section of main page of this repository.
+
+If you have already done that, ensure you have the latest content from the repository.
+
+1. Open your terminal and navigate to the directory where you have cloned the repository.
+2. Run the following command to update your remote references:
+    ```bash
+    git remote update
+    ```
+3. Check the status of your branch with this command:
+    ```bash
+    git status -uno
+    ```
+    - If your branch is up to date, you will see:  ```Your branch is up to date with 'origin/main'.```
+    - If your branch is not up to date, you will see a message like: ```Your branch is behind 'origin/main' by X commits...```
+4. If your branch is behind, update it with:
+    ```bash
+    git pull
+    ```
+
+### Conda Installation
+
+Verify that Conda is installed and you can activate environments.
+
+1. Check the Conda version:
+    ```bash
+    conda --version
+    ```
+    - You should see an output similar to:
+        ```
+        conda X.Y.Z
+        ```
+    - Example:
+
+        <img src="../assets/conda-version.jpg" alt="Conda version" width="300">
+
+2. Test environment activation:
+    - Activate the base Conda environment:
+        ```bash
+        conda activate
+        ```
+        - You should see `(base)` appended before your username in the terminal.
+        - Example:
+        
+            <img src="../assets/conda-activate.jpg" alt="Base Environment Activation" width="300">
+    - Deactivate the base Conda environment:
+        ```bash
+        conda deactivate
+        ```
+
+This checklist will help ensure that you have the necessary setup for a smooth workshop experience. If you encounter any issues, please reach out for assistance.
