 ----------------------
 
 This tutorial will teach you the fundamentals of creating and using Spack environments.
+
 We'll cover:
+
 1. Command line basics -- Creating and managing environments with Spack commands.
+
 2. Configuration files -- Editing ``spack.yaml`` and understanding ``spack.lock``.
+
 3. Environment types -- Understanding Spack-managed vs. independent environments.
+
 4. Reproducible builds -- Sharing and recreating environments across systems.

 If we create environments incrementally, Spack ensures that already installed roots are not re-concretized.
 So, adding specs to an environment at a later point in time will not cause existing packages to rebuild.
 
-Adding and installing specs incrementally leads to greedy concretization, meaning that the environment may concain different package versions compared to an environment created all at once.
