+# iodéOS build instructions
+
+For the most part, building iodéOS is not much different than building [LineageOS](https://lineageos.org/). You can refer for example to LineageOS build instructions for [Pixel 5](https://wiki.lineageos.org/devices/redfin/build). Please note that these instructions concern devices officially supported by LineageOS: in order to build iodéOS for unsupported devices, you will have to create/modify a device tree for your phone.
+
+## Obtaining a basic build: differences with LineageOS instructions
+
+We list here the differences w.r.t. LineageOS build instructions, which are sufficient to obtain a running iodéOS build.
+
+### Part "Install the build packages"
+
+We use [Git LFS](https://git-lfs.github.com/) to maintain the `vendor/extra` repository where prebuilt applications are stored. You must install Git LFS on your system, for example the `git-lfs` package on Debian or Ubuntu.
+
+
+### Part "Initialize the LineageOS source repository"
+
+To initialize the iodéOS source repository, you must replace the Android manifest repository in the `repo init ...` command:
+```
+repo init -u https://gitlab.iode.tech/os/public/manifests/android.git -b v6-staging
+```
+The branch `v6-staging` corresponds to the latest active development branch of iodéOS v6, and may be subject to deep changes. iodéOS official stable release branches will be added when available.
+
+### Part "Download the source code"
+
+After having sucessfully downloaded the sources with the `repo sync` command, you must download the Git LFS stored objects:
+```
+cd vendor/extra
+git lfs pull iode v6-staging
+```
+
+### That's all folks
+
+You can now start building iodéOS, after carefully following LineageOS build instructions.
+
+## Fine-tune your iodéOS build
+
+Some iodéOS features need some more work.
+
+### Make SafetyNet pass
+
+Due to recent changes in the way iodéOS pass safetynet, no more additionnal config is required: it should work out-of-the-box.
+
+### Sign your builds
+
+You can sign your builds with developer keys by creating a directory called `certs` at the root of your source tree, and generating signing keys in it (modify the `subject` variable in the code below). There is no need to modify iodéOS sources, in particular the `PRODUCT_DEFAULT_DEV_CERTIFICATE` variable will be modified accordingly.
+```
+subject='/C=US/ST=France/L=Toulouse/O=iodeOS/OU=iodeOS/CN=iodeOS/emailAddress=suport@iode.tech'
+mkdir certs
+for x in releasekey platform shared media networkstack testkey; do \
+ ./development/tools/make_key certs/$x "$subject"; \
+done
+```
+
+### Configure Smart Charging
+
+Smart charging has been removed, as there is now the new Charging Control feature in LineageOS.

-LineageOS
-===========
-
-Getting started
----------------
-
-To get started with Android/LineageOS, you'll need to get familiar with [Source Control Tools](https://source.android.com/setup/develop).
-
-To initialize your local repository using the LineageOS trees, use a command like this:
-```
-repo init -u https://github.com/LineageOS/android.git -b lineage-22.2 --git-lfs
-```
-Then to sync up:
-```
-repo sync
-```
-Please see the [LineageOS Wiki](https://wiki.lineageos.org/) for building instructions, by device.
-
-
-Submitting patches
-------------------
-Patches are always welcome! Please submit your patches via LineageOS Gerrit!
-
-Simply follow our guide on [how to submit patches](https://wiki.lineageos.org/submitting-patch-howto.html).
-
-To view the status of your and others' patches, visit [LineageOS Gerrit Code Review](https://review.lineageos.org/).
-
-
-Buildbot
---------
-
-All supported devices are built weekly and periodically as changes are committed to ensure the source trees remain buildable.
-
-You can view the current build statuses at [LineageOS Buildkite](https://buildkite.com/lineageos).
-
-Builds produced weekly by the buildbot can be downloaded from [LineageOS downloads](https://download.lineageos.org/).
