# Editable install with no version control (apache-airflow==2.1.0.dev0)

+# This constraints file is meant to be used only in the "apache-airflow" installation command and not
+# in all subsequent pip commands. By using a constraints.txt file, we ensure that solely the Airflow
+# installation step is reproducible. Subsequent pip commands may install packages that would have
+# been incompatible with the constraints used in Airflow reproducible installation step. Finally, pip
+# commands that might change the installed version of apache-airflow should include "apache-airflow==X.Y.Z"
+# in the list of install targets to prevent Airflow accidental upgrade or downgrade.
+#
+# Typical installation process of airflow for Python 3.8 is (with random selection of extras and custom
+# dependencies added), usually consists of two steps:
+#
+# 1. Reproducible installation of airflow with selected providers (note constraints are used):
+#
+# pip install "apache-airflow[celery,cncf.kubernetes,google,amazon,snowflake]==X.Y.Z" \
+# --constraint "https://raw.githubusercontent.com/apache/airflow/constraints-X.Y.Z/constraints-3.8.txt"
+#
+# 2. Installing own dependencies that are potentially not matching the constraints (note constraints are not
+# used, and apache-airflow==X.Y.Z is used to make sure there is no accidental airflow upgrade/downgrade.
