 You should have [git](http://git-scm.com/) installed
 
-	$ git clone git://github.com/kwart/totp-me.git
+```bash
+git clone git://github.com/kwart/totp-me.git
+```
 
 or you can download [current sources as a zip file](https://github.com/kwart/totp-me/archive/master.zip)
 
 ### How to build it
 
-Download `lcrypto-j2me-xxx.zip` ("xxx" - current version of lcrypto, for example "lcrypto-j2me-156.zip") 
-from the [Bouncy Castle website](https://www.bouncycastle.org/latest_releases.html) 
-and extract it to new `lcrypto-j2me` folder.
-
-Copy folder `totp-me/for-lcrypto-j2me/` contents to `lcrypto-j2me` folder.
-
-Correct the lcrypto-j2me version number in `pom.xml` files
-* `lcrypto-j2me/pom.xml`: find `<version>1.56</version>`
-* `totp-me/pom.xml`: find `<artifactId>lcrypto-j2me</artifactId>` .. `<version>1.56</version>`
-
 Install [Maven](https://maven.apache.org).
 
-Build and install lcrypto-j2me
+Download `lcrypto-j2me-xxx` archive ("xxx" - current version of lcrypto, for example "lcrypto-j2me-160.tar.gz") 
+from the [Bouncy Castle website](https://www.bouncycastle.org/latest_releases.html), 
+extract it and install the classes as a JAR file to your local repository:
 
-	$ cd lcrypto-j2me
-	$ mvn clean install
+```bash
+wget https://www.bouncycastle.org/download/lcrypto-j2me-160.tar.gz
+tar xf ./lcrypto-j2me-160.tar.gz
+mvn install:install-file -Dfile=lcrypto-j2me-160/zips/cldc_bccore_classes.zip -DgroupId=org.bouncycastle -DartifactId=lcrypto-j2me -Dversion=1.60 -Dpackaging=jar
+```
 
-Build totp-me
+Build the `totp-me` and feed it with `lcrypto` version from the previous step:
 
-	$ cd ../totp-me
-	$ mvn clean package
+```bash
+mvn clean package -Dlcrypto.version=1.60
+```
 
 This default build uses Microemulator API implementation to simplify the build process, but it's only MIDP-2.0
 implementation. To be sure the source code is __MIDP-1.0 compatible__, you should install Oracle WTK and provide
 path to it to Maven as `wtk.home` system property
 
-	$ mvn clean package -Dwtk.home=/opt/WTK2.5.2
+```bash
+mvn clean package -Dwtk.home=/opt/WTK2.5.2
+```
 
 ### How to run it in the Microemulator
 
 Just use `exec:java` goal after you've successfully built the project
+(provide lcrypto version if needed).
 
-	$ mvn exec:java
+```bash
+mvn exec:java -Dlcrypto.version=1.60
+```
