+
+Just as curl can be built and installed using CMake, it can also be used from
+CMake.
+
+## Using `find_package`
+
+To locate libcurl from CMake, one can use the standard
+[`find_package`](https://cmake.org/cmake/help/latest/command/find_package.html)
+command in the typical fashion:
+
+```cmake
+find_package(CURL 8.12.0 REQUIRED)  # FATAL_ERROR if CURL is not found
+```
+
+This invokes the CMake-provided
+[FindCURL](https://cmake.org/cmake/help/latest/module/FindCURL.html) find module,
+which first performs a search using the `find_package`
+[config mode](https://cmake.org/cmake/help/latest/command/find_package.html#config-mode-search-procedure).
+This is supported by the `CURLConfig.cmake` CMake config script which is
+available if the given CURL was built and installed using CMake.
+
+### Detecting CURL features/protocols
+
+Since version 8.12.0, `CURLConfig.cmake` publishes the supported CURL features
+and protocols (see [release notes](https://curl.se/ch/8.12.0.html)). These can
+be specified using the `find_package` keywords `COMPONENTS` and
+`OPTIONAL_COMPONENTS`, with protocols in all caps, e.g. `HTTPS`, `LDAP`, while
+features should be in their original sentence case, e.g. `AsynchDNS`,
+`UnixSockets`. If any of the `COMPONENTS` are missing, then CURL is considered
+as *not* found.
+
+Here is an example of using `COMPONENTS` and `OPTIONAL_COMPONENTS` in
+`find_package` with CURL:
+
+```cmake
+# CURL_FOUND is FALSE if no HTTPS but brotli and zstd can be missing
+find_package(CURL 8.12.0 COMPONENTS HTTPS OPTIONAL_COMPONENTS brotli zstd)
+```
+
+One can also check the defined `CURL_SUPPORTS_<feature-or-protocol>` variables
+if a particular feature/protocol is supported. For example:
+
+```cmake
+# check HTTPS
+if(CURL_SUPPORTS_HTTPS)
+  message(STATUS "CURL supports HTTPS")
+else()
+  message(STATUS "CURL does NOT support HTTPS")
+endif()
+```
+
+### Linking against libcurl
+
+To link a CMake target against libcurl one can use
+[`target_link_libraries`](https://cmake.org/cmake/help/latest/command/target_link_libraries.html)
+as usual:
+
+```cmake
+target_link_libraries(my_target PRIVATE CURL::libcurl)
+```

 On Windows, `file://` accesses can be converted to network accesses by the

+Starting in curl 8.13.0, curl can be told to download URLs provided in a text
+file, one URL per line. It is done by with `--url @filename`: so instead of a
+URL, you specify a filename prefixed with the `@` symbol. It can be told to
+load the list of URLs from stdin by providing an argument like `@-`.
+
+When downloading URLs given in a file, it implies using --remote-name for each
+provided URL. The URLs are full, there is no globbing applied or done on
+these. Features such as --skip-existing work fine in combination with this.
+
+Lines in the URL file that start with `#` are treated as comments and are
