+  ## ls-packs
+

+
+  Lists the emoji packs and metadata specified in the manifest.
+
+  ### Options
+
+  - `-m, --manifest PATH/URL` - path to a custom manifest, it can
+    either be an URL starting with `http`, in that case the
+    manifest will be fetched from that address, or a local path

+
+  Fetches, verifies and installs the specified PACKS from the

+
+  - `-m, --manifest PATH/URL` - same as ls-packs

+  ## gen-pack
+
+      mix pleroma.emoji gen-pack PACK-URL
+
+  Creates a new manifest entry and a file list from the specified
+  remote pack file. Currently, only .zip archives are recognized
+  as remote pack files and packs are therefore assumed to be zip
+  archives. This command is intended to run interactively and will
+  first ask you some basic questions about the pack, then download
+  the remote file and generate an SHA256 checksum for it, then
+  generate an emoji file list for you.
+
+  The manifest entry will either be written to a newly created
+  `index.json` file or appended to the existing one, *replacing*
+  the old pack with the same name if it was in the file previously.
+
+  The file list will be written to the file specified previously,
+  *replacing* that file. You _should_ check that the file list doesn't
+  contain anything you don't need in the pack, that is, anything that is
+  not an emoji (the whole pack is downloaded, but only emoji files
+  are extracted).
