+Build
+=====
+
+Build the sopc2dts tool:  
+
+```
+$ git clone http<git remote>/sopc2dts.git
+$ cd sopc2dts
+$ make
+```
+
+Test the sopc2dts tool: test with `--gui`, in case fix typical errors.  
+
+```
+$ java -jar sopc2dts.jar --gui
+```
+
+
+Usage
+=====
+
+```
+$ java -jar ./sopc2dts.jar --force-altr -i ./<my project name>.sopcinfo -o <my project name>.dts
+```
+
+
+Issues
+======
+
+*  Installation verification fails as follows  
+
+```
+$ java -jar sopc2dts.jar --gui
+    Refusing to load . It does not exist
+```
+
+Fix typical sopc2dts errors: in case configure another java version  
+
+```
+$ sudo update-alternatives --config java
+```
+
+*  `Component sdram_pll of class altera_pll is unknown`
+alt_pll changed name to altera_pll -> in case may fix it in the java, or setup pll section yourself  
+
+*  addresses in DTS are decimal -> may edit the addresses to hex yourself
