 ## Installation
-### Build dependencies
 
-PROJ requires C and C++11 compilers.
-It also requires SQLite3 (headers, library and executable).  The minimum 
-version of SQLite3 required is 3.11
+Consult the [Installation](https://proj.org/install.html) page of the official
+documentation.
+For builds on the master branch, [install.rst](https://github.com/OSGeo/PROJ/blob/master/docs/source/install.rst)
+might be more up-to-date.
 
-### Building with CMake
-
-    cd proj
-    mkdir build
-    cd build
-    cmake ..
-    cmake --build .
-
-On Windows, one may need to specify generator:
-
-    cmake -G "Visual Studio 15 2017" ..
-
-If the SQLite3 dependency is installed in a custom location, specify the
-paths to the include directory and the library:
-
-    cmake -DSQLITE3_INCLUDE_DIR=/opt/SQLite/include -DSQLITE3_LIBRARY=/opt/SQLite/lib/libsqlite3.so ..
-
-Tests are run with
-
-    ctest
-
-The test suite requires that the proj-datumgrid package is installed
-in `PROJ_LIB`.
-
-### Building on Unix/Linux
-
-FSF's configuration procedure is used to ease installation of the
-PROJ system.
-
-The default destination path prefix for installed files is `/usr/local`.
-Results from the installation script will be placed into subdirectories
-`bin`, `include`, `lib`, `man/man1` and `man/man3`.
-If this default path prefix is proper, then execute:
-
-    ./configure
-
-See the note below if you are building PROJ directly from the git repository.
-
-If another path prefix is required, then execute:
-
-    ./configure --prefix=/my/path
-
-In either case, the directory of the prefix path must exist and be
-writable by the installer.
-After executing configure, execute:
-
-    make
-    make install
-
-The install target will create, if necessary, all required sub-directories.
-
-Tests are run with
-
-    make check
-
-The test suite requires that the proj-datumgrid package is installed
-in `PROJ_LIB`.
-
-#### Building from the git repository
-
-If you are building from the git repository you have to first run
-
-    ./autogen.sh
-
-which will generate a configure script that can be used as described above.
