+### dts-check
+
+Validate dts files and improve board & patch development overall
+
+This option validates the dts/dtb file for the selected board against the device tree bindings, and outputs the validation logs to the user. It can be used when adding a new board, developing or improving a dts file.
+
+Usage:
+```bash
+./compile.sh dts-check BOARD=nanopi-r5c BRANCH=edge 
+```
+### inventory-boards
+
+Outputs a one board per-line CSV inventory of boards.
+
+Sets `TARGETS_FILE` to something that doesn't exist, so the `default-targets.yaml` is used (so same list for everyone, save for userpatched-boards)
+
+Usage:
+```bash
+./compile.sh inventory-boards
+```
+Outputs /info/boards-inventory.csv
+
+### kernel-dtb
+
+Builds only DTB, and output full preprocessed dts source
+
+Outputs preprocessed DTS source for board in question to `output/`
+also outputs same preprocessed DTS source, ran through `dtc` with input and output DTS formats for "normalized" comparisions
+
+Usage:
+```bash
+./compile.sh kernel-dtb BOARD=xxxxx BRANCH=edge
+```
+
+### rewrite-uboot-patches
+
+Prepares git, applies patches to git, and re-writes them back from git
+same as kernel, it does git archeology for mbox-less patches, etc.
+
+- uboot-patches-to-git alias is also added, but my guess is rewrite is more useful.
+- refactor a common config function for both kernel and uboot.
+
+Usage:
+```bash
+./compile.sh rewrite-uboot-patches BOARD=xxxx BRANCH=edge 
+```
+
+### targets
+
+Generates output/info/git_sources.json file that will contain url, branch and commit hash combo.
+
+The easiest way to generate file for all devices is to run `./compile.sh targets`. Then at the time of release we will copy the output/info/git_sources.json file to config/sources/git_sources.json. Once the file is copied, the hash information from the file will be used to fetch resources for git repositories where branches are specified instead of tags or commits.
+
+Usage:
+```bash
+./compile.sh targets
+```

 These parameters are meant to be applied to the `./compile.sh` command. They are **all** optional. They can also be added to your [build configuration file](/Developer-Guide_Build-Preparation/#providing-build-configuration) to save time. Default values are marked **bold** if applicable.
