Edit:
We have now a temporary git repository at gitorious:
http://gitorious.org/replicant

== Build system ==
 * root your phone
 * Backup your current system!!!
 * Check out the Dream Android repository :
{{{
 mkdir replicant
 cd replicant
 repo init -u git://gitorious.org/replicant/manifest.git
 repo sync
}}}

Build process:
Let's say that our build directory is ~/replicant
 * Add that file:
{{{
TARGET_PRODUCT := htc_dream
}}}
 To ~/replicant/buildspec.mk 
 * Then type
{{{
 cd ~/replicant
 export ANDROID_JAVA_HOME=$JAVA_HOME
 make
}}}
 * The files to flash are in ~/replicant/out/target/product/dream,flash them and then clear the cache
 * boot and push the wifi firmware if you want it




== Status ==
 * web browser crashes
 * ril seem to work(I made some calls and received sms,but can't receive calls) 
 * sound on the application cpu(the baseband cpu has sound too) now works
