 ## Known Issues
 At the moment preferences on Gtk frontend do not take effect, and as such this menu is currently disabled. This issue is inherited from NetSurf and will be amended soon.
 
 ## Building and installation
-In the root of the source tree:
-```sh
-$ mkdir -v build
-$ cd build
-```
-
 To build with both Visurf and Gtk frontends:
 ```sh
-$ cmake .. -DCMAKE_INSTALL_PREFIX=/usr
+$ cmake -B build -DCMAKE_INSTALL_PREFIX=/usr
 ```
 To build with Visurf only:
 ```sh
-$ cmake .. -DCMAKE_INSTALL_PREFIX=/usr -DNEOSURF_BUILD_GTK_FRONTEND=OFF
+$ cmake -B build -DCMAKE_INSTALL_PREFIX=/usr -DNEOSURF_BUILD_GTK_FRONTEND=OFF
 ```
 To build with Gtk only:
 ```sh
-$ cmake .. -DCMAKE_INSTALL_PREFIX=/usr -DNEOSURF_BUILD_VI_FRONTEND=OFF
+$ cmake -B build -DCMAKE_INSTALL_PREFIX=/usr -DNEOSURF_BUILD_VI_FRONTEND=OFF
 ```
 To build libneosurf only (no frontend):
 ```sh
-$ cmake .. -DCMAKE_INSTALL_PREFIX=/usr -DNEOSURF_BUILD_GTK_FRONTEND=OFF -DNEOSURF_BUILD_VI_FRONTEND=OFF
+$ cmake -B build -DCMAKE_INSTALL_PREFIX=/usr -DNEOSURF_BUILD_GTK_FRONTEND=OFF -DNEOSURF_BUILD_VI_FRONTEND=OFF
 ```
 
 Then:
 ```sh
-$ make
-$ sudo make install
+$ make -C build
+```
+
+And as root:
+```sh
+# make -C build install
 ```

 At build-time, NeoSurf requires the following programs:
 * python3
 * cmake
 * any CMake-compatible build utility (typically GNU make)
-* a POSIX-compliant shell
+* Z Shell
 * gperf
 * flex
 * bison or byacc
 * pkg-config or pkgconf
-* Z Shell
 
 At runtime and build-time, the following libraries and their development headers are required:
 * libcurl
