+# AddJsonPackage
+
+In each directory that utilizes `CPMUtil`, there must be a `cpmfile.json` that defines dependencies in a similar manner to the individual calls.
+
+The cpmfile is an object of objects, with each sub-object being named according to the package's identifier, e.g. `openssl`, which can then be fetched with `AddJsonPackage(<identifier>)`. Options are designed to map closely to the argument names, and are always strings unless otherwise specified.
+<!-- TOC -->
+- [Options](#options)
+- [Examples](#examples)
+<!-- /TOC -->
+
+## Options
+
+- `package` -> `NAME` (`PACKAGE` for CI), defaults to the object key
+- `repo` -> `REPO`
+- `version` -> `VERSION`
+- `ci` (bool)
+
+If `ci` is `false`:
+
+- `hash` -> `HASH`
+- `hash_suffix` -> `HASH_SUFFIX`
+- `sha` -> `SHA`
+- `key` -> `KEY`
+- `tag` -> `TAG`
+  * If the tag contains `%VERSION%`, that part will be replaced by the `git_version`, OR `version` if `git_version` is not specified
+- `url` -> `URL`
+- `artifact` -> `ARTIFACT`
+  * If the artifact contains `%VERSION%`, that part will be replaced by the `git_version`, OR `version` if `git_version` is not specified
+  * If the artifact contains `%TAG%`, that part will be replaced by the `tag` (with its replacement already done)
+- `git_version` -> `GIT_VERSION`
+- `git_host` -> `GIT_HOST`
+- `source_subdir` -> `SOURCE_SUBDIR`
+- `bundled` -> `BUNDLED_PACKAGE`
+- `find_args` -> `FIND_PACKAGE_ARGUMENTS`
+- `download_only` -> `DOWNLOAD_ONLY`
+- `patches` -> `PATCHES` (array)
+- `options` -> `OPTIONS` (array)
+- `skip_updates`: Tells `check-updates.sh` to not check for new updates on this package.
+
+Other arguments aren't currently supported. If you wish to add them, see the `AddJsonPackage` function in `CMakeModules/CPMUtil.cmake`.
+
+If `ci` is `true`:
+
+- `name` -> `NAME`, defaults to the object key
+- `extension` -> `EXTENSION`, defaults to `tar.zst`
+- `min_version` -> `MIN_VERSION`
+- `extension` -> `EXTENSION`
+- `disabled_platforms` -> `DISABLED_PLATFORMS` (array)
+
+## Examples
+
+In order: OpenSSL CI, Boost (tag + artifact), Opus (options + find_args), discord-rpc (sha + options + patches).
