+??? info "Miniconda installation and setup"
+    [Miniconda](https://docs.anaconda.com/free/miniconda/index.html) is a free minimal installer for conda. 
+
+    These quick command line instructions will get you set up quickly with the latest Miniconda installer. For graphical installer (`.exe` and `.pkg`) and hash checking instructions, see [Installing Miniconda](https://docs.anaconda.com/free/miniconda/miniconda-install/).
+
+    === "Windows"
+        These three commands quickly and quietly install the latest 64-bit version of the installer and then clean up after themselves. To install a different version or architecture of Miniconda for Windows, change the name of the `.exe` installer in the `curl` command.
+
+        ```bash
+        curl https://repo.anaconda.com/miniconda/Miniconda3-latest-Windows-x86_64.exe -o miniconda.exe
+        start /wait "" miniconda.exe /S
+        del miniconda.exe
+        ```
+        After installing, open the “Anaconda Prompt (miniconda3)” program to use Miniconda3. For the Powershell version, use “Anaconda Powershell Prompt (miniconda3)”.
+    
+    === "macOS"
+        These four commands quickly and quietly install the latest M1 macOS version of the installer and then clean up after themselves. To install a different version or architecture of Miniconda for macOS, change the name of the `.sh` installer in the `curl` command.
+
+        ```bash
+        mkdir -p ~/miniconda3
+        curl https://repo.anaconda.com/miniconda/Miniconda3-latest-MacOSX-arm64.sh -o ~/miniconda3/miniconda.sh
+        bash ~/miniconda3/miniconda.sh -b -u -p ~/miniconda3
+        rm -rf ~/miniconda3/miniconda.sh
+        ```
+
+        After installing, initialize your newly-installed Miniconda. The following commands initialize for bash and zsh shells:
+
+        ```bash
+        ~/miniconda3/bin/conda init bash
+        ~/miniconda3/bin/conda init zsh
+        ```
+
+    === "Linux"
+        These four commands quickly and quietly install the latest 64-bit version of the installer and then clean up after themselves. To install a different version or architecture of Miniconda for Linux, change the name of the `.sh` installer in the `wget` command.
+
+        ```bash
+        mkdir -p ~/miniconda3
+        wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh -O ~/miniconda3/miniconda.sh
+        bash ~/miniconda3/miniconda.sh -b -u -p ~/miniconda3
+        rm -rf ~/miniconda3/miniconda.sh
+        ```
+
+        After installing, initialize your newly-installed Miniconda. The following commands initialize for bash and zsh shells:
+
+        ```bash
+        ~/miniconda3/bin/conda init bash
+        ~/miniconda3/bin/conda init zsh
+        ```
