 In addition to the above requirements, if you plan on building PSPSDK from
 source, you will need:
 
-* Make. Note: GNU Make may not be required, but if you run into problems
+* **GNU Make** - You can find GNU Make at http://www.gnu.org/software/make/.
-  building from source you may want to install it. You can find GNU Make
-  at http://www.gnu.org/software/make/.
 
-If you plan on building PSPSDK directly from the Git repository you will need:
+* **GNU autotools** - You will need a recent version of autoconf (http://www.gnu.org/software/autoconf/) and automake (http://sourceware.org/automake/).
 
-* A Git client. A popular client for Windows is TortoiseGit

-### Installation from binary
-
-Download the PSPSDK binary package specific to your development system.
-For example, if you are using Windows, you will want to download the file
-pspsdk-1.0-win32.zip.
-
-Extract or unzip the package into the folder where the PSPDEV toolchain is
-installed.  For example, on a Windows system you may have installed the PSPDEV
-toolchain to C:\pspdev. You would then unzip PSPSDK into C:\pspdev.
-
-Update your PATH environment variable to point to the PSPSDK tools directory.
-In the above example, if you installed PSPSDK to C:\pspdev, you would add
-C:\pspdev\bin to your PATH.
 
 ### Installation from source

+This command will configure the system for the PSPSDK installation
+
+```
+./configure

+
+This will build the PSPSDK using all available processor cores
+
+```
+make -j $(getconf _NPROCESSORS_ONLN)
+```
+
+This will build the PSPSDK documentation
+
+```
+make doxygen-doc
+```
+
+> **Note** 
+> If you haven't installed Doxygen or don't want to build the library documentation, you can skip this.
+
+This will install the PSPSDK(Default installation path: `/usr/local/pspdev/`)
+
+```
+make install
+```
+
+> **Note**
+> If you are on Windows, you can use WSL2 and follow this installation as is. 
+
+### Installation from Docker Image
+
+If you want to develop apps and games for PSP without installing from the source
+you can use Docker, see https://docs.docker.com/get-docker/ how to get started 
+according to your OS.
+
+after you install the Docker, just run this command to download the docker image:
+
+```
+docker pull pspdev/pspdev:latest
+```
+
+when it successfully downloaded, run this command to get 
+started(It will use your WSL2 env):
