+Install NGINX server.
+
 Copy [60-ghostream.conf module](doc/nginx/modules-available/60-ghostream.conf) to `/etc/nginx/modules-available/60-ghostream.conf`.
+Then symlink this file to `/etc/nginx/modules-enabled/60-ghostream.conf`.
 
 Copy [ghostream site](doc/nginx/sites-available/ghostream) to `/etc/nginx/sites-available/ghostream`.
+Then symlink this file to `/etc/nginx/sites-enabled/ghostream`.
+
+Restart NGINX.
+
+You may need to generate SSL certificates.
+For the initial generation, you may comment the SSL rules and use Certbot NGINX module.
 
 ### OvenMediaEngine
 
+Install some required libraries,
+
+```bash
+sudo apt update
+sudo apt install --no-install-recommends build-essential ca-certificates nasm autoconf zlib1g-dev tcl cmake curl libssl-dev libsrtp2-dev libopus-dev libjemalloc-dev pkg-config libvpx-dev libswscale-dev libswresample-dev libavfilter-dev libavcodec-dev libx264-dev libfdk-aac-dev
+```
+
+Then compile libsrt,
+
+```
+curl -LOJ https://github.com/Haivision/srt/archive/v1.3.3.tar.gz
+tar xvf srt-1.3.3.tar.gz
+cd srt-1.3.3
+./configure --prefix="/opt/ovenmediaengine" --enable-shared --enable-static=0
+make -j 2
+sudo make install
+cd ..
+```
+
+Then compile OvenMediaEngine FFMpeg,
+
+```
+curl -LOJ https://github.com/AirenSoft/FFmpeg/archive/ome/3.4.tar.gz
+tar xvf FFmpeg-ome-3.4.tar.gz
+cd FFmpeg-ome-3.4
+./configure --prefix="/opt/ovenmediaengine" --enable-gpl --enable-nonfree --extra-cflags="-I/opt/ovenmediaengine/include" --extra-ldflags="-L$/opt/ovenmediaengine/lib -Wl,-rpath,/opt/ovenmediaengine/lib" --extra-libs=-ldl --enable-shared --disable-static --disable-debug --disable-doc --disable-programs --disable-avdevice --disable-dct --disable-dwt --disable-error-resilience --disable-lsp --disable-lzo --disable-rdft --disable-faan --disable-pixelutils --disable-everything --enable-zlib --enable-libopus --enable-libvpx --enable-libfdk_aac --enable-libx264 --enable-encoder=libvpx_vp8,libvpx_vp9,libopus,libfdk_aac,libx264 --enable-decoder=aac,aac_latm,aac_fixed,h264 --enable-parser=aac,aac_latm,aac_fixed,h264 --enable-network --enable-protocol=tcp --enable-protocol=udp --enable-protocol=rtp --enable-demuxer=rtsp --enable-filter=asetnsamples,aresample,aformat,channelmap,channelsplit,scale,transpose,fps,settb,asettb
+make
+sudo make install
+cd ..
+```
+
+Finally compile OvenMediaEngine,
+
+```
+curl -LOJ https://github.com/AirenSoft/OvenMediaEngine/archive/v0.10.7.tar.gz
+tar xvf OvenMediaEngine-0.10.7.tar.gz
+cd OvenMediaEngine-0.10.7/src
+# Ajouter dans projects/base/ovlibrary/AMS.mk et projects/modules/dtls_srtp/AMS.mk et projects/orchestrator/AMS.mk et projects/monitoring/AMS.mk : $(call add_pkg_config,srt)
+make release
+sudo make install
+```
+
 Copy [Server.xml](doc/ovenmediaengine/conf/Server.xml) to `/usr/share/ovenmediaengine/conf/Server.xml`.
 
 Now enable and start OvenMediaEngine, `sudo systemctl enable --now ovenmediaengine`.
