+## Compilation on Red Hat-based Linux
+
+
+### Install package dependencies:
+#### RedHat/Fedora
+```bash
+    sudo dnf install mesa-libGL-devel gcc cmake rapidjson-devel \
+    libupnp openssl sqlcipher sqlcipher-devel \
+    botan2 botan2-devel json-c-devel bzip2-devel asio-devel libsecret libXScrnSaver-devel
+```
+
+To compile with Qt5:
+```bash
+   sudo dnf install qt5-qtbase-devel qt5-qtmultimedia qt5-qtx11extras
+```
+
+To compile with Qt6:
+```bash
+   sudo dnf install qt6-qtbase-devel qt6-qtmultimedia-devel qt6-qt5compat-devel
+```
+
+Additional dependencies for Feedreader plugin:
+```bash
+   sudo dnf install libxml2-devel libxslt-devel libcurl-devel
+```
+
+### Checkout the source code
+```bash
+   cd ~ 
+   git clone https://github.com/RetroShare/RetroShare.git retroshare
+```
+
+### Checkout the submodules
+```bash
+   cd retroshare
+   git submodule update --init --remote libbitdht/ libretroshare/ openpgpsdk/ retroshare-webui/
+   git submodule update --init --remote supportlibs/librnp supportlibs/restbed supportlibs/rapidjson
+```
+
+### Compile
+```bash
+   qmake CONFIG+=release CONFIG+=rs_jsonapi CONFIG+=rs_webui
+   make
+```
+
+The executable produced will be:  
+```bash
+ ./retroshare-gui/src/retroshare
+```
+
+### Install
+```bash
+   sudo make install
+```
+
+The executable produced will be:  
+```bash
+ ~/usr/bin/RetroShare  
+```
+
+### For packagers
+
+Packagers can use PREFIX and LIB\_DIR to customize the installation paths:
+```bash
+   qmake PREFIX=/usr LIB_DIR=/usr/lib64 "CONFIG-=debug" "CONFIG+=release"
+   make
+   make INSTALL_ROOT=${PKGDIR} install
+```
+
+### SQLCipher
+If libsqlcipher is not available as a package
+
+You need to place sqlcipher so that the hierarchy is:
+
+        ~Home
+          |
+          +--- retroshare
+          |
+          +--- lib
+                |
+                +---- sqlcipher
+```bash
+	mkdir lib
+	cd lib
+	git clone https://github.com/sqlcipher/sqlcipher.git --depth=1 --branch v3.4.1
+	cd sqlcipher
+	./configure --enable-tempstore=yes CFLAGS="-DSQLITE_HAS_CODEC" LDFLAGS="-lcrypto"
+	make
+	cd ..
+```
+
+### Build infos
+
+For the `FeedReader` it is required to append the config option `CONFIG+=retroshare_plugins`.
+Make sure `plugins/plugins.pro` contains `FeedReader` in the list of plugins to compile. 
+
+Do not mix plugins compiled with Qt5 with those compiled with Qt6. They work only if they are compiled
+with the same Qt version as RetroShare.
+
+Voip is outdated and is not compileable on the latest Debian.
+
+For `Autologin` it is required to append the config option `CONFIG+=rs_autologin`.
+
+
+### Build options
+
+* Mandatory
+  * release or debug:			normally you would like to use the release option
+* Extra features (optional)
+  * rs_autologin:				enable autologin
+  * retroshare_plugins:			build plugins
+  * rs_webui:					enable Web interface
+  * rs_jsonapi:					enable json api interface, required by rs_webui
+  * gxsthewire:					enable Wire service (experimental)
+  * wikipoos:					enable Wiki service (experimental)
+  * rs_use_native_dialogs:		enable native dialogs (may cause crashes with some versions of Gtk)
+  * rs_deep_channels_index:		build with deep channel indexing support
+  * rs_deep_files_index:		build with deep file indexing support
+  * "CONFIG+=..."				enable other extra compile time features, you can find the almost complete list in file *<sourcefolder>\retroshare.pri*
+
+Example:
+
+```batch
+qmake CONFIG-=debug CONFIG+=release CONFIG+=rs_use_native_dialog CONFIG+=rs_gui_cmark
+qmake CONFIG+=rs_jsonapi CONFIG+=rs_webui CONFIG+=rs_autologin
+qmake CONFIG+=rs_deep_channels_index CONFIG += gxsthewire CONFIG += wikipoos
+```
