+# Linux builds
+
+Tested on: fedora36, ubuntu22
+vm minimalish specs:
+
+* 4 core cpu
+* 17gb RAM
+* 50gb storage
+
+It's mostly a matter of doing once:
+```
+## pick build type:
+# cd linux
+# cd linux-mar
+
+make fetch
+
+## pick your os:
+# sudo make setup-fedora
+# sudo make setup-debian
+
+make bootstrap
+```
+Then, to build:
+```
+make all
+```
+That should produce the (non-updating) setup.exe and the community portable zip. There is a second directory `linux-mar` where you can build the so-called `.mar` version of LibreWolf. This is te version that will be auto-updating someday. It's main drawback is some nasty theming bug.

 * **If your LibreWolf crashes on startup**, you're probably missing the right [Visual C++ Runtime](https://support.microsoft.com/en-us/topic/the-latest-supported-visual-c-downloads-2647da03-1eea-4433-9aff-95f26a218cc0). You'll want the _Visual Studio 2015, 2017 and 2019_ version for **x64**, which would be **[this file](https://aka.ms/vs/16/release/vc_redist.x64.exe)**.
 * The latest type of **.zip files** allows for a user profile inside the extracted folder. It is _self-contained_ and runs on removable storage.
