+If you aren't interested in getting the complete commit history, you can speed up this process:
+
+```bash
+git clone https://github.com/RagnarokResearchLab/CommunityProjects.git --recursive --shallow-submodules
+```
+
+To further reduce the time needed to clone, you may want to skip nested dependencies as well:
+
+```bash
+git clone https://github.com/RagnarokResearchLab/CommunityProjects.git --shallow-submodules
+```
+
+Finally, you could override the parallelism factor, which defaults to an overly conservative value:
+
+```bash
+git clone https://github.com/RagnarokResearchLab/CommunityProjects.git --shallow-submodules --jobs=8
+```
+
+The difference will be quite signitifcant, as shown by the following comparison table:
