+## macOS
+* Add the packages:
+
+ ```
+ brew install ffmpeg nginx postgresql openssl gcc make redis git yarn
+ ```
+* Run the services:
+
+ ```
+ brew services run postgresql
+ brew services run redis
+ ```
+
+## Gentoo
+
+* Add this to ``/etc/portage/sets/peertube``:
+```
+net-libs/nodejs
+sys-apps/yarn
+media-video/ffmpeg[x264] # Optionnally add vorbis,vpx
+dev-db/postgresql
+dev-db/redis
+dev-vcs/git
+app-arch/unzip
+dev-lang/python:2.7
+www-servers/nginx
+
+# Optionnal, client for Let’s Encrypt:
+# app-crypt/certbot
+# app-crypt/certbot-nginx
+```
+
+* If you are on a "stable" Gentoo you need to accept the testing keyword ~amd64 yarn:
+```
+mkdir -p /etc/portage/package.keywords
+cat << EOF >> /etc/portage/package.keywords/peertube
+# required by yarn (argument) for PeerTube
+sys-apps/yarn ~amd64
+EOF
+```
+
+* Compile the peertube set:
+```
+emerge -a @peertube
+```
+
+* Initialize the PostgreSQL database if you just merged it:
+```
+emerge --config postgresql
+```
+
+* (For OpenRC) Enable and then start the services (replace with the correct PostgreSQL slot):
+```
+rc-update add redis
+rc-update add postgresql-11
+rc-service redis start
+rc-service postgresql-11 start
+```
+
