+1. In your web browser,  go to:  
+[https://conda-forge.org/download/](https://conda-forge.org/download/)
+2. Click on the tile corresponding to your platform (e.g., Windows, macOS, or Linux) to download the installer. If you are unsure about your macOS or Linux architecture, open a command line terminal and run:
+
+   ```bash
+   uname -m
+   ```
+
+   Alternately, you can also download the installer using the command line on macOS or Linux by running:
+
+   ```bash
+   curl -L -O "https://github.com/conda-forge/miniforge/releases/latest/download/Miniforge3-$(uname)-$(uname -m).sh"
+   ```
+
+3. Once you have downloaded miniforge installer, run it to install conda. Note: you may need 
    admin permissions during the installation process.
-    - **Windows**
-        1. Find the file you downloaded (`Miniforge3-Windows-x86_64.exe`) and
-           double click to execute it. Follow the instructions to complete the
-           installation.  
-           Note: In the Advanced Installation Options there is an installer setting for adding 
-           Miniforge3 to the PATH variable, we recommend that this it is checked.
-        2. Once the installation has completed, you can verify it was correctly
-           installed by searching for the "miniforge prompt" in your Start menu.
-    - **Mac OS**
-        1. Open your Terminal (you can search for it in spotlight - `cmd` +
-           `space`)
-        2. Navigate to the folder you downloaded the installer to. For example,
-           if the file was downloaded to your Downloads folder, you would enter:
-
-            ```bash
-            cd ~/Downloads
-            ```
-
-        3. Execute the installer with the command below. You can use your arrow
-           keys to scroll up and down to read it/agree to it.
-
-            ```bash
-            bash Miniforge3-MacOSX-x86_64.sh -b
-            ```
-            Note: when asked if you wish to initialize, we recommend that you answer `yes`.
-        4. To verify that your installation worked, close your Terminal window
-           and open a new one. You should see `(base)` to the left of your
-           prompt.
-        5. You can also initialize miniforge manually, with the command below. This makes sure
-           that your terminal is set up correctly for your python installation.
-
-            ```bash
-            conda init
-            ```
-
-    - **Linux**
-        1. Open your terminal application
-        2. Navigate to the folder you downloaded the installer to. For example,
-           if the file was downloaded to your Downloads folder, you would enter:
-
-            ```bash
-            cd ~/Downloads
-            ```
-
-        3. Execute the installer with the command below. You can use your arrow
-           keys to scroll up and down to read it/agree to it.
-
-            ```bash
-             bash Miniforge3-Linux-x86_64.sh -b
-            ```
-
-        4. To verify that your installation worked, close your Terminal window
-           and open a new one. You should see `(base)` to the left of your
-           prompt.
-        5. Finally, initialize miniforge with the command below. This makes sure
-           that your terminal is set up correctly for your python installation.
-
-            ```bash
-            conda init
-            ```
+
+   ### Windows
+
+   1. Find the file you downloaded (e.g. in your Downloads directory), it should look like `Miniforge3-Windows-x86_64.exe`. 
+   2. Double-click with the left mouse button to execute it. 
+   3. Follow the instructions to complete the installation. We recommend checking the options to "Create start menu shortcuts" and "Add Miniforge3 to my PATH environment variable".
+   4. Once the installation has completed, you can verify it was correctly installed by searching for the “miniforge prompt” in your Start menu.
+
+   ### macOS & Linux
+
+   1. Find the file you downloaded (e.g. in your Downloads directory), it should look like `Miniforge3-MacOSX-arm64.sh` or `Miniforge3-Linux-x86_64.sh`.
+   2. Using the command line, navigate to the location of the installer. For example, if it's in the Downloads directory, you can run:
+
+   ```bash
+   cd ~/Downloads
+   ```
+
+   3. Run the installer by typing:
+
+   ```bash
+   bash Miniforge3-$(uname)-$(uname -m).sh
+   ```
+
+   4. The installer will walk you through a series of prompts to complete the installation. We recommend that you use the default installation location, but you can change it to a different location in your user directory if you prefer. 
+
+   5. Once the installation finishes, the installer will ask:  
+   `Do you wish to update your shell profile to automatically initialize conda?`  
+   We recommend you answer `yes` to this question. This will add the necessary lines to your shell profile to ensure that `conda` is added to your PATH variable and properly initialized when you open a new shell. Note: For changes to take effect, you will need to close and re-open your current shell.
+
+   6. Once the installation has completed, you can verify it was correctly installed by opening a new command line. You should see `(base)` next to your command line prompt. Additionally, the following command:
+
+   ```
+   echo $CONDA_PREFIX
+   ```
+
+   should return the path to your `miniforge` installation, by default this is `~/miniforge3` (i.e., `miniforge3` in your home directory), so for example:
+
+
+   ```bash
+   /Users/username/miniforge3
+   ```
+
+   or
+
+   ```bash
+   /home/username/miniforge3
+   ```
+
+   #### Manual initialization
+
+   If you did not have the installer initialize your shell, you can manually initialize it. Note: the command depends on installation location of `miniforge`, by default this is `~/miniforge3`. Then, run:
+
+   ```bash
+   ~/miniforge3/condabin/conda init
+   ```
+
+   Again, for changes to take effect, you will need to close and re-open your current shell.
