 After the binary has built successfully it is available in `target/release`.
 
-### Final steps
-
-In order to make the binary globally accessible you will need to add it to `PATH` so it's recommended you move it to a general folder.
-
-
-Examples:
-
-- Linux/MacOS
-  - ```shell
-    mkdir ~/crunchy-cli
-    mv /path/to/repo/target/release/crunchy-cli ~/crunchy-cli/crunchy # OR
-    mv /path/to/downloaded/file/crunchy-cli(rest of filename here) ~/crunchy-cli/crunchy
-    export PATH=$PATH:~/crunchy-cli
-    ```
-    
-    For persistent usage you should add the above export to your `.shellrc`(.bashrc, .zshrc ,etc. file)
-- Windows
-  - Download the `.exe` file or build it yourself. Rename it to the way you will be calling it (ex: `crunchy.exe`) and move it into a folder where it's easily accessible. Afterwards follow a [guide](https://www.wikihow.com/Change-the-PATH-Environment-Variable-on-Windows) for adding that folder to the `PATH` variable. A restart of `CMD` or `powershell` might be required for the changes to take effect.

+### Url Filtering
+
+If you want to download only specific episode of a series, you could either pass every single episode url to the downloader (which is fine for 1 - 3 episodes) or use _filtering_.
+
+It works pretty simple, just put a specific pattern surrounded by square brackets at the end of the url from the anime you want to download.
+A season and / or episode as well as a range from where to where episodes should be downloaded can be specified.
+Use the list below to get a better overview what is possible
+- `...[E5]` - Download the fifth episode.
+- `...[S1]` - Download the full first season.
+- `...[-S2]` - Download all seasons up to and including season 2.
+- `...[S3E4-]` - Download all episodes from and including season 3, episode 4.
+- `...[S1E4-S3]` - Download all episodes from and including season 1, episode 4, until and including season 3.
+- `...[S3,S5]` - Download episode 3 and 5.
+- `...[S1-S3,S4E2-S4E6]` - Download season 1 to 3 and episode 2 to episode 6 of season 4.
+
+In practice, it would look like this: `https://www.crunchyroll.com/series/GY8VEQ95Y/darling-in-the-franxx[E1-E5]`.
+
+The `S`, followed by the number indicates the _season_ number, `E`, followed by the number indicates an _episode_ number.
+It doesn't matter if `S`, `E` or both are missing.
+Note that `S` must always stay before `E` when used.
+
+There is also a regex available at [regex101.com](https://regex101.com/r/SDZyZM) where you can test if your pattern is correct.
+Just put in your pattern without square brackets into the big empty field and if the full pattern is highlighted this means it is valid.
+If none or only some parts are highlighted, it's not valid not.
