 Synchronet uses [[dev:Git]] for its Source Repository (as of August, 2020).
+===== Updating an Install from CVS =====
+So you previously installed Synchronet for *nix using the ''install/GNUmakefile'' method, which resulted in "checking-out" the source files from  [[dev:CVS]] before building them and now you want to get the [[http://cvs.synchro.net/gitpushlog.ssjs|latest updates]] since the switch to [[dev:Git]].
+  - Follow the **[[#Clone]]** instructions below, cloning into a sub-directory off of your Synchronet install directory (e.g. ''/sbbs/repo'').
+  - If you previously had any ''localdefs.mk'' files (e.g. ''src/build/localdefs.mk'' or ''src/sbbs3/localdefs.mk'') you will want to copy or move those files into the corresponding location in the new ''repo/src/'' sub-directory.
+  - Now go through your normal build steps (e.g. running ''make symlinks'') in the ''repo/src/sbbs3'' sub-directory, adding ''RELEASE=1'' or whatever build options you're used to using. Once the build is complete, due to the ''symlinks'' target, your executable binary files in ''/sbbs/exec/'' should now be updated with the "latest and greatest" Synchronet development version.
+  - If you want the latest ''[[dir:ctrl]]/[[custom:text.dat]]'' changes (you probably do) or the latest files from ''[[dir:text]]'', ''docs'', ''[[dir:xtrn]]'', ''[[dir:web]]'', or ''webv4'', you will need to either copy those files or symlink them to their equivalent in the ''repo'' sub-directories at this time. **DO NOT** copy or symlink over your other ''[[dir:ctrl]]/*'' files or you will lose important configuration settings. If you have any locally modified files in your ''[[dir:exec]]'' directory, you'll want to move those to your ''[[dir:mods]]'' directory before overwriting them with upstream files.
 ===== Clone =====
@@ Line 12: / Line 21: @@
 To clone the repository to your local system (into a directory named ''/sbbs/repo'') using unauthenticated HTTPS:
-  $ git clone https://gitlab.synchro.net/sbbs/sbbs.git /sbbs/repo
+  $ git clone https://gitlab.synchro.net/main/sbbs /sbbs/repo
 To clone the repository to your local system using SSH (your public key must be configured for your user account at ''gitlab.synchro.net''):
-  $ git clone git@gitlab.synchro.net:sbbs/sbbs.git /sbbs/repo
+  $ git clone git@gitlab.synchro.net:main/sbbs /sbbs/repo

+==== Branches ====
+The ''master'' branch may occasionally not successfully build for your specific platform. If this happens, checking out the latest successful-nightly-build for your platform should resolve this issue. e.g. for Linux-x64:
+  $ git checkout dailybuild_linux-x64
+If you wish to switch back to the ''master'' branch a later point:
+  $ git checkout master
 ==== Read-only Directories ====
@@ Line 31: / Line 49: @@
 This approach is feasible even for sysops that make changes to files in ''exec'' and ''text'' by using a local branch (i.e. merging in upstream changes from the ''master'' branch), but that setup should be pursued only by experienced Git users.
+**Note:**\\
+If you do decide to change your configured ''exec'' directory, be sure to update your ''[[config:env#SBBSEXEC]]'' environment variable to point to the correct location too.
 ===== Create and Checkout a Branch =====

   $ git pull
-  $ git merge master

 ===== Push Without Merge Commit =====
@@ Line 57: / Line 78: @@
   hint: See the 'Note about fast-forwards' in 'git push --help' for details.
-To avoid a 'merge commit', do this (assuming you only made one commit before attempting the push):
+To avoid a 'merge commit'
-  $ git reset --soft HEAD~1
+  $ git pull --rebase --autostash
-  $ git pull
+Then push your changes.
-Then re-add/commit, and push your changes.
+==== 'up' alias ====
+To create a convenient alias for the ''git pull --rebase'' usage  above:
+  $ git config --global alias.up "pull --rebase --autostash"
+Now you can just run ''git up'' instead of ''git pull''.
 ===== Push Without Password =====
@@ Line 75: / Line 100: @@
 With that change, if your SSH public key is registered with your ''gitlab.synchro.net'' user account, ''git'' should automatically authenticate for ''push'' requests.
+===== Stash =====
+A ''git pull'' fails with the message:
+  error: Your local changes to the following files would be overwritten by merge:
+Whether you knowingly or intentionally modified any files, or [[dev:Git]] just did it automatically (e.g. changing line-endings of text files), the suggested solution is to "Stash Local Changes":
+  - Run ''git diff -w'' in the repo (show changes, ignoring white-space) and confirm that no file differences are shown. If file differences **are** shown, you can still proceed with these instructions.
+  - Run ''git stash'' in the repo to push any changed (or presumed changed) files into your local git stash. If you wish, you can use ''git stash show'' to display what changes are currently stashed.
+  - Run ''git pull'' in the repo to merge any upstream changes into your local repo.
+  - Run ''git stash pop'' in the repo to re-apply the changes previously pushed to your local git stash. If there were in fact no local changes, this will actually do nothing but empty the local git stash. If there are "merge conflicts" when the stashed changes are reapplied, there will be ''CONFLICT'' warnings that you will need to address by editing the listed files.
+  - Run ''git diff'' in the repo (show changes, including white-space) to confirm that either //no changes// or only your //expected// changes are shown.
+===== Reset =====
+If you're getting Git errors about local changes to files that you didn't make and you just want to reset every file in the repository to its latest upstream contents, run these commands:
+  $ cd /path/to/sbbs/repo
+  $ git fetch --all
+  $ git reset --hard origin/master
+  $ git checkout master
+After the successful execution of these commands, your ''sbbs'' Git repo should be reset back to the current upstream contents.
+===== Delete the Repo =====
+Under normal circumstances, you should **never** need to delete your Synchronet source repository (the ''sbbs/repo'' directory) and it is strongly advised that you do not:
+  - Most installations use symbolic links from the ''sbbs/[[dir:exec]]'' directory to the build output directories of the ''sbbs/repo''. Deleting the repo would delete your working executable binary files.
+  - The repo is your copy of the working source code. Deleting the repo would delete your copy of your working source code.
+  - Just ''git pull'' to update your ''sbbs/repo'' to the latest and greatest source, if that's what you're trying to do.
