+Pinned Requirements
+===================
+
+The requirements in this folder are pinned to specific versions to allow recreating
+a specific build. This is useful in cases such as building documentation on readthedocs
+or for debugging since this specific build is known to work on both Windows and Linux
+with python 3.10.
+
+If you only want to install all of the development dependencies for spectroplot, it is
+recommended to instead use:
+
+.. code-block:: console
+
+    pip install spectroplot[dev]
+
+or clone the repository by following the
+`installation guide <https://spectroplot.readthedocs.io/en/latest/contributing.html#setting-up-development-environment>`_
+in the documentation.
