 ## Usage
 
-For more examples, please refer to the [**documentation**](https://kandayo.github.io/likee-scraper/Likeer.html).
+For more examples, please refer to the [**documentation**](https://absolab.xyz/likee-scraper).
+
+### Download profile by @username
+
+Looking up a user by username requires an additional API request. It's strongly
+recommended to use User IDs. Usernames must be prefixed with an "@".
 
 ```bash
-# Archive the user feed, but stop when encountering the first already-downloaded post.
-# Note: this is the default behaviour.
-likeer store --fast-update <USER>
+$ likeer -u @username
+```
+
+### Download profile by ID
 
-# Archive the last 5 posts of <USER>.
-likeer store -n 5 <USER>
+If a identifier does not have a prefix, it is assumed to be an User ID.
+
+```bash
+$ likeer -u 11111111
+```
+
+### Batch file
+
+If `--batch-file <file.txt>` (or `-a`) is given, Likee will read *file.txt*
+expecting @usernames and IDs to download, one identifier per line.
+Lines starting with "#" or empty lines are considered as comments and ignored.
+
+Usernames must be prefixed with an "@", e.g. `@username`.
+
+IDs must not be prefixed with an "@", e.g. `1111111`.
+
+```bash
+$ cat batch.txt
+~> # Comment (ignored)
+~> @username
+~> 111111111
+$ likeer -a batch.txt
+```
+
+### Fast update
+
+If `--fast-update` (or `-f`) is given, Likeer stops when arriving at the
+first already downloaded video. This flag is recommended when you use Likeer
+to update your personal Likee archive.
+
+```bash
+$ likeer -u @username -f
+# => Example Username - 000003.mp4 [========================] 12.1 MB / 12.1 MB
+# => Example Username - 000002.mp4; skipping
+# => User @username in sync!
 ```
