    "It is confusing to create new cells in a single notebook as different branches.  When these need to be merged, it is difficult to find the correct places in the json tree to manually merge.  Opening different .ipynb files for a new branch in a project is a better idea.  The the git can be used to keep a seperate history of each notebook on a differnt branch, and they can be merged into master on occasion to keep them updated for a summary notebook that includes information and links to the individual topic notebooks.    \n",

	"It is confusing to create new cells in a single notebook as different branches. When these need to be merged, it is difficult to find the correct places in the json tree to manually merge. Opening different .ipynb files for a new branch in a project is a better idea. The the git can be used to keep a seperate history of each notebook on a differnt branch, and they can be merged into master on occasion to keep them updated for a summary notebook that includes information and links to the individual topic notebooks. \n",
