+The Miniforge base is installed at `/opt/GEOSpyD/26.7.2-0/YYYY-MM-DD`, where
+`YYYY-MM-DD` is the date of installation. The date lets installations on
+different days coexist; an environment installed again on the same day must
+use a different prefix or wait until the next day.
+
+On Linux, ffnet requires `gfortran` 8.3 or newer; by default its absence or
+an ffnet build failure stops installation. Use `--ignore-ffnet-errors` to
+continue without ffnet. On macOS, a missing compiler skips ffnet automatically.
 
 ## Usage
 
 ```
 Usage: ./install_miniforge.bash --python_version <python version> --miniforge_version <miniforge> --prefix <prefix>
-                   [--micromamba | --mamba] [--blas <blas>] [--ffnet-hack]
+                   [--micromamba | --mamba] [--blas <blas>] [--ffnet-hack] [--ignore-ffnet-errors]
 
    Required arguments:
       --python_version <python version> (e.g., 3.14)
-      --miniforge_version <miniforge_version version> (e.g., 26.3.2-0)
+      --miniforge_version <miniforge_version version> (e.g., 26.7.2-0)
       --prefix <full path to installation directory> (e.g, /opt/GEOSpyD)
 
    Optional arguments:
       --blas <blas> (default: accelerate, options: mkl, openblas, accelerate, blis)
       --micromamba: Use micromamba installer (default)
       --mamba: Use mamba installer
       --ffnet-hack: Install ffnet from fork (used on Bucy due to odd issue not finding gfortran)
+      --ignore-ffnet-errors: Continue if ffnet fails or gfortran is unavailable/too old on Linux (default: fail installation)
       --help: Print this message
 
    By default we use the micromamba installer on both Linux and macOS
-   For BLAS, we use accelerate on macOS and MKL on Linux
+   For BLAS, we use accelerate on Apple Silicon and MKL elsewhere
 
    NOTE 1: This script installs within /opt/GEOSpyD with a path based on:
 
         1. The Miniforge version
         2. The date of the installation
+   The Python environment is created under envs/py<python version>.
 
-   For example: ./install_miniforge.bash --python_version 3.14 --miniforge_version 26.3.2-0 --prefix /opt/GEOSpyD
+   For example: ./install_miniforge.bash --python_version 3.14 --miniforge_version 26.7.2-0 --prefix /opt/GEOSpyD
 
    will create an install at:
-       /opt/GEOSpyD/26.3.2-0/2026-03-11
+       /opt/GEOSpyD/26.7.2-0/YYYY-MM-DD/envs/py3.14
 
   NOTE 2: This script will create or substitute a .mambarc
   and .condarc file in the user's home directory.  If you
   have an existing .mambarc and/or .condarc file, it will be
   restored after installation.  We do this to ensure that the
   installation uses conda-forge as the default channel.
