+- `realnewslike`: 15 GB
+- `multilingual`: 14 TB
 
 The `en.noblocklist` variant is exactly the same as the `en` variant, except we turned off the so-called "badwords filter", which removes all documents that contain words from the lists at https://github.com/LDNOOBW/List-of-Dirty-Naughty-Obscene-and-Otherwise-Bad-Words.
 
 # How do I download this?
 
-Unfortunately we ran out of time making this into a proper Huggingface dataset, accessible through the `datasets` Python package. Until we get that ready, please use git to do the download. First, make sure you have [Git Large File Storage](https://git-lfs.github.com) installed. Once that is done, downloading the whole dataset, all three variants, is easy:

-git clone https://huggingface.co/datasets/allenai/c4
+git clone --depth 1 --branch mC4_3.1.0 https://huggingface.co/datasets/allenai/c4

-This will download 13TB to your local drive. If you want to be more precise with what you are downloading, follow these commands instead:
+This will download 18 TB to your local drive.
+If you want to be more precise with what you are downloading, download the repo like this:
 
 ```bash
-GIT_LFS_SKIP_SMUDGE=1 git clone https://huggingface.co/datasets/allenai/c4
-cd c4
-git lfs pull --include "en/*"
+GIT_LFS_SKIP_SMUDGE=1 git clone --depth 1 --branch -mC4_3.1.0 https://huggingface.co/datasets/allenai/c4
 ```
 
-The `git clone` command in this variant will download a bunch of stub files that Git LFS uses, so you can see all the filenames that exist that way. You can then convert the stubs into their real files with `git lfs pull --include "..."`. For example, if you wanted all the Dutch documents from the multilingual set, you would run
