You can checkout a tag with `git checkout tags/TAGNAME`, where `TAGNAME` is the tag, for example `v1.20`.

 #### Windows
 
+There are **no runtime libraries** needed for Windows.

 Please use the prepackaged binaries in [Releases](https://github.com/BeamMP/BeamMP-Server/releases/).
 
 Dependencies for **Windows** can be installed with `vcpkg`.
 These are:
 ```
-lua

-rapidjson
-openssl
-websocketpp
-curl
+lua zlib rapidjson openssl websocketpp curl

-- libz
-- rapidjson
-- lua5.3
-- ssl / openssl
-- websocketpp
-- curl (with ssl support)
+We recommend Ubuntu 22.04 or Arch Linux. Any Linux distribution will work, but you have to figure out the package names yourself (please feel free to PR in a change to this README with that info).

+7. Run `make -j` . This step will take some time and will use a lot of CPU and RAM. Remove the `-j` if you run out of memory. *If you change something in the source code, you only have to re-run this step.*
