 ### Bootstrapping instructions
 
 This guide explains the process of building *fpm* on a platform for the first time.
-If your platform and architecture are already supported, download the binary from the [release page](https://github.com/fortran-lang/fpm/releases) instead.
+To build *fpm* without a prior *fpm* version a single source file version is available
+at each release.
 
-#### Download this repository
+To build manually using the single source distribution use
 
-```bash
-$ git clone https://github.com/fortran-lang/fpm
-$ cd fpm/
 ```
-
-#### Build a bootstrap version of fpm
-
-You can use the install script to bootstrap and install *fpm*:
-
-```bash
-$ ./install.sh
+mkdir _tmp
+curl -LJ https://github.com/fortran-lang/fpm/releases/download/v0.2.0/fpm-0.2.0.f90 > _tmp/fpm.f90
+gfortran -J _tmp _tmp/fpm.f90 -o _tmp/fpm
+_tmp/fpm install --flag "-g -fbacktrace -O3"
+rm -r _tmp
 ```
 
-By default, the above command installs `fpm` to `${HOME}/.local/bin/`.
-To specify an alternative destination use the `--prefix=` flag, for example:
+To automatically bootstrap using this appoach run the install script
 
-```bash
-$ ./install.sh --prefix=/usr/local
 ```
-
-which will install *fpm* to `/usr/local/bin`.
-
-To test that everything is working as expected you can now build *fpm*
-with itself and run the tests with:
-
-```bash
-$ cd fpm
-$ fpm test
+./install.sh
 ```
+
+You can set your Fortran compiler and the compiler flags with the ``FC`` and ``FFLAGS``
+environment variables.
