How can I enable mods in Cities Skylines?

Solution 1:

Windows OS

To install mods in the Cities Skylines usually, I will do this.

In the browser

1. Log in to Steam and navigate to the mod, e.g. https://steamcommunity.com/sharedfiles/filedetails/?id=1406625743
2. Subscribe to the mod
3. Once that is done, the Steam client automatically download the subscribed mod in the game computer/laptop

On the computer (I am using Windows 10, should work for Windows 8.1 too)

4. Open Cities Skylines - Play
5. On the screen, you will find Content Manager. Select it.
6. In the Content Manager screen you will find the MODS on the left side. Select it.
7. On the right side, you need to enable the mod you want to be available in the game. Refer this image link for the screens.
8. To uninstall a mod, you can unsubscribe it either from the Steam Workshop page (where you previously subscribed) or from the MODS section of the Content Manager screen by clicking x button on the right side.

Note

Due to some reason, if you couldn't find your subscribed mod in the MODS section of the content manager, sign out the Steam client on your machine and sign in again.
