+## How to work with existing project
+
+1. Check that you have git-lfs installed `git lfs status`
+2. Pull existing repo `git pull https://gitlab.com/ProcyonLotor/vrchat-template.git` and optionally pull all LFS objects `git lfs fetch --all`
+(repo will take much more disk space, but will have complete project history)
+3. (Optional) Some VPM packages might come from Community Repositories,
+add them from project's [vpm-repositories.txt](./vpm-repositories.txt) file to CreatorCompanion,
+or run this command in project's folder `FOR /F %L IN (.\vpm-repositories.txt) DO vpm add repo %L`
+(command requires `vpm` tool installed, see [vpm cli](https://vcc.docs.vrchat.com/vpm/cli/))
+
 > **IMPORTANT**: When opening a previously worked on project on a new machine, Unity may warn you about script errors and suggest you enter Safe Mode,
 > this is because VPM has not loaded yet and didn't resolved the required packages, ignore the errors and continue loading.
 > Sometimes you may need to reopen the project couple times for all packages to resolve and scripts to recompile.
